Having problems with aftermarket wheel cylinder for rear for 70 challenger had two sets put in, go to bleed brakes they start leaking out of the rubber seals. All new parts from front to back any idea

crappy parts are a part of life...id go for a set of wagners...id steer clear from autozone pep boys crap

First set was from autozone and sec. set came from napa can you tell me who sells wagner :

we have a local big a store that does...you do have the brakes all installed before you try to bleed them yes?

Yes from front to back

I just bought some rears from RockAuto, but haven't installed them yet. They're Raybestos brand, and stamped "Made in USA". I haven't had any problems with Raybestos stuff in the past. Good luck.

I just bought some "Dorman" ones and the cellophane wrapping says in big bold letters "made in china. Not installed yet/fingers crossed. I thought Dorman was good ole made in USA like w their freeze plugs etc

Went thru the same thing. NAPA cylinders can be hit or miss, USA made or China junk. I just bought 1/2 dozen USA made from Carquest. Gonna stock up...

If you can get the kits why not just rebuild them?I have done these many times and have had more problem with new ones then the ones I rebuilt.

Just bought two-one from USA and one from China,guess what the crap form overseas dosen`t fit the cutout in the backing plate!!!Any sources for the USA made ones?I`m stopping by NAPA tommorow.

Since the company that provides Napa United and Raybestos shut down all their US and Canadian plants within the last few years and started putting Chinese trash in their boxes, if you find any made in USA ones, grab them and stash them away if you don't need them just now.

My old cylinders were stamped "Lockheed".Probably should have kept them...
