Just did a rear brake job. Did not replace wheel cylinders. Seem to have problems with the rear drivers side I can't seem to get rid of the air when I try and bleed this cylinder. The rear passengers side I can get rid of any excess air no problem. My guess is that the rear drivers side wheel cylinder is shot. If it was the master cylinder my guess is that all 4 brakes would be unbleedable? Yes I started with the rear passenger side wheel cylinder. Please help.

I'd say your on the right track. Usually if its the master you won't be able to get pressure. Sound like the wheel cylinder to me.

Sounds right to me but also check to see if the brake line has a junction along the axle where it splits left and right. There could be a loose or corroded connection, but most likely it is a rt. wheel cyl.

Thanks

I will change it out tomorrow and keep you guys posted. I well check the junction point to make sure it isn't leaking. Thanks.

Update

It was the wheel cylinder. Switched both of them out (rears) and no more air when I bleed all the wheels. Looks like they had got tightened to much at some point (probably me) . It had crushed the inside cone/mating surface where the flare end of the brake line meets the wheel cylinder. This was apparently allowing air to be sucked into the brake fluid (But it wasn't leaking which made it harder to diagnose). Live and learn. Thanks for the help.
