Hi All

I need some help. where would i find the parts book and /or manual for a brake cylinder on a DHB-3 drum brake assy. the wheel cylinder has decided to no longer keep the hydraluic fluid inside and puke all over the wheel..... mumble mumble

does anyone know the part numbers of the associated seals- been searching on the web- having no luck

thanks folks

They can get munched if the shoes wear so much that the oring peeks out past the edge of the brake cylinder.
Buy at least a dozen from any reputable oring supply. You will possibly need several as you learn the installation technique.
So be sure to look for the bit that was sheared off from the oring, it may be swimming around in the cylinder.
Do a search of "bleeding brakes" for ideas on how to best bleed system after replacing the hardware.
Red Hydraulic Fluid only!

Looks like I'm in the same boat. Ordered the rubber O-rings from Univair, but they can keep their wheel cylinder/sleeve and piston parts for the price they're asking. HOLY COW! Do any of you know where to get them for a reasonable price? I wonder if I were to have a dozen wheel cylinder/piston complete assemblies made, if I could sell them for a reasonable price to shortwing owners. So again, do you all know of any sources for these parts out there?
 
Subsonic,
There are usually some wheel cylinders & phone elated parts available from planes upgraded to disc brakes, like I just did on 14P.
Send me a private message with your contact info &phone and I think I can set you up with my old ones removed from my plane.
They are kinda grundgy but should be serviceable

Shane, did you get your situation sorted out?

Yep all good now
the shoes where also badly adjusted- the plunger was coming out one side- got that straightened out

I also am in need of some repair parts or kits to fix my brake cylinders on my colt abut I see these pilots who had the same problem last posted in early 2000. REN
 
Drum brakes. I have a 1961 Colt. Univair doesn't seem to list the brake cylinder or any repair kit for it. I'd appreciate any lead on where to find these repair parts.
 
Here are some photos of the brakes on my 61 Colt. The brake cylinder that pushes the shoes out is leaking. I need to find replacement cylinders or a repair kit. REN

Hi REN,

Did you not look at the links I put just above your post?

Item #13, O rings, is the "rebuild kit" for the cylinders. Two per wheel.

Sorry, didn't mean to send those photos again. Thanks for the info. I feel a little better about braking into them....forgive the pun.
 
Hi again,

There are also tow more O rings involving the brakes. They are on the fitting the goes through the backing plate. #14, and #24.

Sorry for not even noticing your second set of pictures were just a copy of the earlier post. I'm especially aware **** happens to us all.

Jim, thanks for your help. Hopefully I can get these brakes working and get airborne soon.
 
Ren, the link Jim and I posted is the parts manual from the Univair website. Using your serial number you can find the proper parts for your PA22-108.
