My last post was a question about my brakes on the -6 as they only had a bit

over 100 hours on them.  I have received my new brake pads and the tool and

replaced the brakes on the left side.  Now I am on to the right side and

find the brakes on that side are not worn out.  Is it OK to leave them as is

and only replace the one side?  Also, what might cause one side to wear more

than the other like that?  Maybe I turn that way more often I don't know.

Tim,

 It is perfectly OK to do only one side. Most pilots use more right brake, just as they use right rudder on take off.

Yes

Chances are that the brake cylinder isn't easily riding on the pins.  If 
	


they're dirty or rusty, clean them up really good .... and put them back 

together dry.  No lube.

I doubt that's the case ..... of course the left side could be dragging 
	


and wearing out the pads ..... yopu might want to clean up those pins too.

Listers,

 Pardon my poor choice of words below. I should have stated that you can often wear one the brakes out on one side due to a prevailing cross wind or a number of other factors.

Thanks Linn and Charlie!



I will check how free the parts are all moving on the left side and then go

fly.  Even if it wears a bit more on one side it hasn't caused me any grief

and the pads for one side are only $15.

Yeah, but it's a PITA to change the pads.  I would find out what's going 
	


on and fix it.  You'd hate to have a brake go out when you really need 

it.  And the cost may be more than $15 then!

'Bout thirty minutes at most on an RV. Pads can removed from the wheel 

assembly in less time than it takes to remove the wheel pant.

Agreed...I just removed both break calipers, replaced the o rings, cleaned them thoroughly, riveted new pads, installed, safety wire, etc...all in about an hour and a half..not a big job by any standards...



BTW, harbor freight sells a really cool one man vacuum bleed kit that you hook air up to, and it has a nice large reservoir for collecting the brake fluid...plus a fluid supply bottle with a ball valve...nifty...$29.

Paul,

 You are forgetting one thing about that Harbor Freight brake bleeder tool. It's designed for automotive gylcol based fluids, which means that it's O-rings and seals are made from EDPM, not Nitrile or Viton. You'll need to flush out the aircraft mineral oil based brake fluid immediately after use, if you expect to use the thing more than a few times.

Paul,

 If you plan to use that tool exclusively for aircraft, you could simply replace all the seals and O-rings with items made of Nitrile (also called Buna N).

Actually, you should use "viton" for the o-rings on the calipers.  They

will stand the heat and chemical compatability.  The regular o-rings in

the master cyl's are fine.  Change'm as necessary.
