Default Sticky Brakes

My brakes require me to pull the pedal up by hand so they do not drag. This is especially true after I have just landed.

My question is... Is something going wrong with the brake system or do I simply need to put a stronger spring on the master cylinder?

Default Common Issue

Do a quick search and you will find a couple suggested solutions like springs and/or a continous long bolt instead of the short bolts on each side.

I had a similar problem. Loosened the bolts that attach the pedals and it went away. Remember to put the cotter pin in!!

I have seen people tightened those brake bolts down to 25 inch pounds or so because that's the spec for AN3 bolts. This is obviously an area where the spec is thrown out the window and a little brain power must be applied.

I had the same issue with my brakes slightly dragging (enough to groan a little) so I picked up some springs that I bought at Ace Hardware. The springs are a perfect fit and help bring the brakes pedals all the way back. Sorry, I don't remember the part numbers.

Hope that helps,

My only concern is that it is getting worse. I was worried the seals may be deteriorating or something of the likes. It sounds like I just need to disassemble, clean and maybe put fresh/better springs on.

Thanks guys.

Sid, two fixes usually found here.

One is long bolt, fixes any misalignment issues on the pedal pivots.



Just remember, in this usage, the bolts are actually pivots/axles, and not clamping devices.

The other is booster springs, see this thread go to post 7 for photos and parts list. In fact, read the whole thread for some good info about the long bolts.

I have done both on my 10, simple and easy.

I had my bolts overtightened. Backing them off a bit took care of the problem.

Default Skicky Brakes

How many hours do you have on your plane?
Is this something new that is happening?
What brake fluid are you using?

Default put springs on Matco's

After 300 hours my brakes began to drag. The quick effective fix for me was using springs #181(I believe) from ACE hardware on the Matco shafts, but I am still going to replace the pivot points with the long bolt. Does anyone have the AN # required for the bolt?
