Patrick:



Any photos of cool mods would be appreciated.  



Speaking of wheel pants.  My friend who has a RV 10 here in Paris was 

out at a grass strip this weekend.  He had a loose right wheel pant from 

the bolt holding the hexagonal support breaking.  Fortunately,  No major 

damage done and we took the wheel pants off before anything was 

seriously damaged.  He's now getting one of the upgraded axle supports 

made.   Only 56 hrs on the hobbs. He's probably had the airplane for 20 

hrs.  Lives on a grass strip also.

For the newbies in the group, here's what part Fred is talking

Oh, by the way, we put the calipers on yesterday and it occurred to me that normally the bleed screw would be on the top to get the air out.  Is it done this way to keep the brake line from being damaged on grass strips if it were on the bottom?



And where did I see the exact height of the installed canopy with wheels on?  We'll soon be wondering about clearing the garage door!

Lew,



The bleeders go on the bottom of the caliper, you need to relocate one of them...check the plans...it's in there.

Well, it does work on your car!!!

Not really.  Aircraft brake systems are usually bled from the bottom up 
	


and the bleed fitting is where the fluid goes in.  This doesn't mean 

that bleeding from the top down isn't effective ..... it's just easier 

to bleed up.

Thanks for the replies, Guys.  I tried to reply through email so as not to clutter up the forum, but the email wouldn't go through.



We already put the bleeders on the bottom as instructed, just seemed backwards to me.



Linn,  you fill the system from the bottom up?  ... really?  Sounds messy and impractical.  I've bled cars from the top down for the past 40 yrs. -- first plane, so clue me in!

 

Use a hand pump, put a hose on the nipple and force fluid all the way up through the pedal cylinders to the reservoir?  But then the nipple has to be loose to allow fluid in?  One side then the other?  And I must admit I haven't read ahead to see if it's covered in a later section -- just got the calipers on and had to call it a night.

 

Puzzled, - Lew

I don't see it in the directions, but yes, fill a pump type oil can up

with brake fluid, and put a hose between it and the bleeder.  Open the

bleeder and pump the fluid UP through the system until it fills the

master cylinder.  you may have to remove some from the master cylinder

to make room for more, so you can pump enough until all the bubbles

are out.  It works, and works well.  Yes, definitely different than

doing cars.

I did the same on cars..... a few years longer.  I don't know why 
	


airplanes have to be different.  It's just the way I was taught.

Yes.  ACS sells a rather pricey coupling to make things easier:   
	


http://www.aircraftspruce.com/catalog/lgpages/brake_bledders.php



I've used one (borrowed) and it sure makes it easier.  Used a plain 

garden sprayer that it was attached to.   Only caveat is that the fluid 

attacked the rubber in the sprayer.



I've also used a large plastic syringe with better success than the hand 

pump (read squeeze type oil can) because your hand gets really tired 

really quickly!

I haven't either.  I kinda doubt it's there, but will be pleasantly 
	


surprised if it is.

Hate to tell ya this Lew, but the puzzlement is just starting.  Don't

Another thought is that you really can replace the nipple with something 

else to make filling easier.  Just be quick swapping the nipple back in.

I'm sure Tim meant to say "aviation hydraulic  fluid" rather than "Brake Fluid".  

  

  

       I don't see it in the directions, but yes,  fill a pump type oil can up

      with brake fluid, and put a hose between it and the  bleeder.

Geez, I thought we were supposed to use red kool-aid, so that's

what I used.  Isn't that it?



Good catch...yep, whatever you do, DO NOT use automotive brake

fluid....use aircraft stuff.  And, rather than start another long

debate about synthetic ATF vs. standard aircraft hydraulic vs. the

newer better stuff.....perhaps just dig around on the net for

that, because there really is no conclusive answer like

"you MUST use this...".   For me, I have the standard aircraft

hydraulic fluid for now.  Time will tell.

"Brake Fluid" seems to be blasphemy.



OK, I can do that.  But you know I'm not that easy ... Why?

Flammability?  Corrosive?  Altitude issues?  Not pretty enough?  



Keep it simple -- I don't need molecular analysis, or a discussion of whether synthetics are really synthetics or not.  Brand names?
