Graham, Raimo, et. al.,

In looking at ACS trying to find specs on my old ACS reservoir, I see

that ACS no longer sells this model.  The latest model has a machined 

aluminum body.  I would bet that one could be sealed with a non-vented

1/8 NPT plug so that if filled to capacity, it would take the brake system

pressures.  

But then you would still have the problem of brake wear requiring more 

fluid in the calipers and you would have to add fluid to the reservoir.  And 

when you put on new brake pads, you'd have to remove the extra fluid 

from the reservoir.  Same problem as with only the master cylinder 

except that the reservoir may be easier to access.

One really needs some sort of valving between the reservoir and master

cylinder to allow the fluid to move back and forth when that is necessary

or seal the system for brake operation.

Raimo,

you would need to use a resevoir that can take full brake pressure. You 

would probably burst it if you try hard braking.

For those people who are content with the existing master cylinder set up 

and do not want to modify it, you may find my method worth trying. I use a 

plastic nozzle usually supplied with mastic cartridges as a funnel. Cut the 

end back until it can be screwed into the filler hole, stuff some rag around 

the base of it, pour a drop of fluid in, pump the brake leaver a few times, 

remove the nozzle, screw the filler cap back on and remove the rag, job 

done! Takes about 5 mins.

Pumping the leaver blows any air out that enters when you remove the plug 

and if there is a small amount left in the funnel after doing so, on 

removing the funnel it is soaked up by the rag and also ensures the cylinder 

is full to the brim prior to refitting the plug.

Only pour a very small amount into the funnel, which leaves plenty of room 

for fluid to be pumped out of the cylinder along with any air when operating 

the leaver. With each stroke of the leaver give the air time to rise up 

through the fluid in the funnel before releasing it and sucking the fluid 

back into the cylinder.

 Fellow Europaphiles,



 I have started a new album on my site: "Brake Reservoir Study."  So  far, 

 there are 4 pics of the ACS brake reservoir with some descriptive  text.



 Next step will be to identify the following elements:



 1. Fitting to screw into the bottom of the reservoir to attach a hose.

 2. Hose

 3. Fitting to screw into the fill-hole of the master cylinder to which 

 the other end of the hose will attach.

 4. Some sort of check valve to go in the system somewhere to enable  the 

 brake master to generate the pressure necessary to function rather  than 

 just squirt brake fluid back into the reservoir.



 Any ideas or suggestions are welcome!



 Check six,

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Wow,

 Not to throw rain on the parade, but the brake system is simple.   Graham and Jim Naylor are nicely saying it but I'll be the bad guy.

  

 I hate my original Europa Master Cylinders but they are simple and  light.  

 Europa supplies a threaded aluminum filler that works like Jim  Naylor's.  Open the plug, screw it in and fill the cylinder.  If you  have a bubble still in the brake due to it's angle, take out the holding screws  and lean the cylinder to allow that bubble to escape (normally not necessary for  floor mount).  This works great for the typical fill when the pads are  wearing thin maintenance operations.

  

 As for bleeding.

 I bleed from the bottom up using a syringe filled with the appropriate  fluid and push it up to the top.  I get real lazy and put a 1/4 inch  silicone rubber tube in the threaded hole (it seals around the threads well  enough) and run the silicone tube to a cup under the wheel well to allow  overflow to come out of the master fill cap and travel down to the cup  via the inside of the wheel well.  This way I can monitor how I'm  doing.  When you pull the tube out, the fluid level in the cylinder is  topped off automatically.   For the floor mounted brakes, I pull the  carpet (just in case) and put the silicone tube in and run it vertical out a  small hole in the pilots footwell. 

  

 Another thing.  Europa supplies a buna brake seal that works great,  just in case you forgot to install it originally or it has worn.  You must  have them if using mil spec fluids.

  

 Brake bleed kit funnel is about $15

 Buna Seals:  O-ring BS113 and the brake cup N7193  (trigear) are  about the same price.  

 These seals are great, and with the filler makes for a no drip system (OK,  some, because I have never bled brakes without a mess of some sort on the  floor).

 Just email Roger at Europa and save some engineering time.  

  

 As Jim eludes to the fact, it's pretty simple as is, and Graham notes there  are many other concerns when trying to mod these particular cylinders for a  reservoir.  If you must have a reservoir, go to a regular Matco or  similar master cylinder and save the engineering time as it is already done for  you.

  

 Just my thoughts.

  

 Bud

Hi Bob"One really needs some sort of valving between the reservoir and master cylinder to allow the fluid to move back and forth when that is necessary or seal the system for brake operation."I never operated master cylinder for my Mono with fluid in it. I never saw a master cylinder with a fill on the pressure side of the cylinder. Are you absolute sure the fill cap is on the pressure side? Most master cylinders have reservoir on the "when piston is in the home position" will allow flow in or out of  a passage to charge piston with no valve necessary,. When piston is actuated and it seals off the charge passage.If the factory supplied mono master cylinder in fact has the fill on the pressure side of the piston, an easy resolve would be a screw down arrangement. I forget the exact term, perhaps it is "fake piston" or something like that, but i am refering to a model aeroplane diesel. You see you can't start one with full compression, so you unscrew an arrangement on top and it lowers compression, once engine is running you screw it in to increase compression. You don't want any leaks, they figured it out so they don't leak. PAW is one mfg going down to I  think as samll as .030 cubic inches. Anyway idea could be to either use actual  model cylinder, or make a piston that you can screw down and decrease volume, or make an arrangement that does so. In other words it would be another mini master cylinder. Worn brakes tighten, new brakes loosen. You can install on filler of factory master cylinder or "T" it off anywhere brake line.I remember seeing a hang glider tow arrangement, it used an automotive brake disk, and an average run of the mill automotive master cylinder. The disc was attached to the rope spool. The operator could increase or decrease tension (there was a pressure gauge) by screwing a "T" handled screw in or out that actuated the master cylinder instead of ones foot pushing on the lever.Anyway think of the easiest way to squeeze, or unsqueeze the tube of toothpaste so you don't need complex valving. Perhaps a few components from a very simple bicycle master cylinder?Ron Parigoris   [quote][b]

Fellow Mono builders/operators,



Why would you stuff around trying to put a reservoir on the Europa supplied 

Master Cylinder (355 gms WITHOUT reservoir or hand brake feature) when you 

can spend a fortune and have the attached.  (270 gms WITH reservoir and hand 

brake feature).  Not only that, it fits on the stick and lets you do 

something else with your third hand that is needed with the standard Master 

Cylinder as supplied.



Cheers

Kingsley

Hi  Bud,

  

 I agree with that. I am using a seringe to fill the  cylinder and this works for me. I also found that lifting the tail so that the  aircraft is nose down helps complete the filling. An additional suggestion is to  put a rag under the cylinder to prevent possible brake fluid overflow dripping  on the tyre.

G'day Rowland,

  

 http://mcylulm.free.fr/doc/pdf/maitre_cyl_a_main.pdf

  

 Mike Parkin advised us about this little  gem on the list back in June this year so I'm not claiming credit for the  discovery.

  

 Please note that the email address on the  website is incorrect (has a missing "t").  It should be MDOaircraft(at)aol.com (MDOaircraft(at)aol.com)

  

 Also, the cost of the Master Cylinder  only is 232 Euro, not what it says on the website.  Fittings and S.S.  braided hose are extras.

  

 Just got mine this last week and it  certainly is a nicely made unit.

  

 A prospective purchaser will need to  advise:-

    the Stick  Diameter 25mm or 25.4mm    i.e. 1 inch.  If 1 inch, the fitting is reamed out to suit       
if you wish to use red Aeroshell 5606    fluid or plain automobile DOT4 fluid.  Needed to install the proper    seals. Hope this helps

G'day Kingsley,



I have just sent an e-mail to M. Bastein to begin the purchase process of one of his 

MAITRE CYLINDRE DE FREIN « AU MANCHE »along with the necessary fittings and hose to equip a Europa Monowheel.



This is a much tidier solution to the whole Europa Monowheel brake than any cludged up

reservoir attachment to the existing master cylinder.

I can't wait to see what this jewel is going to co$t me but I'm sure it will be worth every centi-Euro

when installed and functioning.

Needless to say, further developments will be posted for the bemusement ( and amusement ) of all.

But I still have the original sticks

and feel the need to jujst get things done!

So setting it aside, at least for now.

Bob,



I am going to the permanently installed refilling bottle. That will be semiplastic, semitransparent and equipped with an easily openable cap. The bottle will be aesthetical and the crown of RT`s cockpit, do not worry. I have also checked it will not prevent the normal use of the brake lever.



The breathing hole is NOT necessary because because it is not an ordinary reservoir.



The tube between the bottle and the cylinder will/must have an OFF-ON valve.

Normally the valve will be always OFF.

I will open it only when the system must be filled or refilled.

That means no changes to the POH.



How to fill (worn pads or very cold):



1) open the cap of the bottle.

2) open the valve.

3) gently make some peaceful strokes by lever

4) close the valve

5) close the cap.



How to refill (when new pads or very hot):



1) as fore

2) as fore

3) gently push some amount the lever and keep it there (there must be space for extra fluid in the bottle!)

4) as fore

5) as fore

6) relax the lever



All this will be one minute task and no mesh and always ideal brakes.



Changing the whole cylinder is not a realistic option for me!



I definetely do not want to spoil and make a new leather upholstery when removing an old cylinder an installing new one. If I were still in the building phase I would absolutely go for it. 



I would love to have also a parking pressure valve! Now I have only a mechanical one (a triangle shape alu sheet with a lanyard connected by a miniatyre pip-pin) but I am happy with it and it makes passenger(s) relaxing because it is so...funny.

Raimo,



That's exactly the scenario I was investigating.  I even have the little transparent reservoir and was ready to plumb it into the cylinder with some sort of valve.  It should work well enough. 



Please post pics of your system once you have it working.  I'm sure there are others out there who would like to implement some similar solution to the lack of master cylinder reservoir.



I'm still awaiting the new master cylinder to be shipped from France.  My plan is to install the new master cylinder on the pilot stick.  Perhaps install another on the co-pilot side at some point in the future if I see a need (allowing my buddy Gary to check others out on the monowheel prior to flying their own?).  Once the new master cylinder is installed and all works well, I will make a new aluminum cover plate to replace the cover with the brake slot.  It will also be slightly larger to extend back and cover the fill hole for the old brake master cylinder.  That will allow a neat solution to the holes in the leather without having to replace the leather cover.

Installing on the stick? That would be absolutely erconomical (HOTAS braking) but could there be some risks lurking??? I know there are some ultras or so with brake lever on the stick.

Raimo,



I can see where there could be issues with a stick mounted brake if one were careless as to how one gripped the stick and brake.  There could be an inadvertent application of the brake if one were not careful.  It will require proper positioning of the brake/lever on the stick so that it is easily accessible when needed but not in the way when not needed.  We'll see how it goes.  Other folks who have it seem to like it.

 ultras or so with brake lever on the stick.


	


Hello Raimo



There is no need to worry about lurking risks with a hand brake on the 

stick.  I have considerable experience using them in gliders and I can 

assure you that with mono wheel aircraft, it is an ideal solution for the 

braking problem.



I cannot even begin to imagine how someone would land with their fist 

clasped around the brake handle on landing because it is such an unnatural 

way to hold the stick but I guess anything is possible.  One thing I have 

noticed however, is the number of power pilots flying with differential foot 

braking that land with their feet high on the pedals with resultant partial 

braking. . . . especially in Cessnas.  This is a terrible habit but it is 

surprising how many do it.



Also, consider the number of push bikes and motor bikes in the world with 

hand operated braking.  If there were any risks lurking, I'm sure the method 

would have been changed by now.



Best regards

Kingsley

Dear Kingsley,



As I wrote that position is "absolutely erconomical " and gives a good possibility to Hands On Throttle And Stick.



My point was only technical not physisical as follows: I see always extremely potential and sometimes even invisible risks when modifying or installing something to the moving parts especially to the plane`s steering components. Good and welknown example: autopilotÂ´s servo could kill many ways like jamming the controls if installed with wrong geometry. 



I only tried to say: please be very careful when installing something extra (not from Manual) to the moving parts!

Could you please accept that point Kingsley?



Of course that (doing mods) is not a problem to pros and other experienced and talented builders.



Anyway Europas are marketing also for the first time builders and other non-technical human educated people like librarians or even to me! Kingsley - can you believe - all of us are not Honeywell or RAF engineers or NASA pilots!



I give you one real example of the lurking devil which was just behind MY stick - please be patient:



During my building phase I installed a fighter style (because I am too so childish) stick grip. I said myself it is necessary because those buttons and switches add safety (by HOTAS!). That was a mod - it was not in my Europa bibble.



I had to run the connection cable (thick, about 20 wires) from the stick (which is moving!) to the seat bottom locker (which is not moving!). I made a little hole in the seat bottom fore glass surface and run the cable through it. After that I tested very carefully all the stick movements. Full fore, aft and sideways. Again and again and again. I did understand there could be something wrong but I did not realize it until...



..suddenly when full fore the stick jammed totally! I could not level the plane anymore in my workshop! In a real life and airborne there were only seconds and the plane would have gone to the bad side of the VNE towards mother ground.



Why: when the stick goes fore, the bottom of it goes aft. So went my stick grip cable also, through the little hole to the seat bottom locker. When I this time tried to pull the stick back, the cable has badly jammed to the sides of the hole. Yes - it was rubber insulated.



Correction: I fixed the cable permanently to the lead-through hole. And hope it will be fixed for ever.



Doing mods - even little ones - it is fascinating, but could be also dangerous.



The brake lever on the stick in itself  is an ideal place for it. That is clear!



Wishes from Finland, 

Raimo OH-XRT

Hello again Raimo,



My comments were in no way meant to offend you so if I did I humbly

apologise.  When you said about 'risks lurking', I thought you meant from

the operational point of view, like what different pilots might do!



Believe me, there is nothing  I disagree with in your reply and now that you

mention it, I will check my autopilot servo yet again.



Please don't think I consider myself in the realm of any Honeywell, RAF

Engineer or NASA pilot.  If you knew of only some of the silly things I have

done Raimo, you would soon realise how ridiculous it would be if I thought

that.  I think it would be more appropriate if I put YOU on a pedestal

because YOU ARE FLYING which is more than I can say.



I always enjoy reading your posts on the forum and I do so with much

respect.  Every post you make is also not in your native tongue and there

has been more than one occasion when I have considered you expressed

yourself better than I could have and English is the only language I have

ever known!



Keep up the good work Raimo.



With the very best of wishes from Oz.



Kingsley



PS  Sorry Raimo, but I was also ignorant of the meaning of HOTAS . . . . 

now I know . . .  looked it up on Google!
