96 Cavalier passenger rear brake lock up when wet or cold
When the brakes are wet or cold the passenger rear brake locks up. I have replaced the following : shoes, hardware, adjusters, wheel cylinders, and drums. Bled all brake lines, took great pains to evenly adjust the "adjusters", even backed off on the driver' side adjustment (driver side brake has never locked up), I had even measured the drums after they were machined to try to insure eveness, and the passenger side still locks up. Any other ideas?

Bad PROPORTION VALVE ... the back brakes should only be doing 30% of the stopping with a bad proportion valve it will send more pressure to the back during braking and cause it to lock up. Good Luck and thanks for using FIX YA

Timbo, Sounds like the right back brake hardware may be damaged or seizing. Take in for free inspection at some larger repair places. To show your appreciation press the helpful button and follow me on fixya for more tips and info.
i would have the rear brake limiter mechanism checked first as this device regulates brake pressure so it is equal to both back wheels, if this is ok i'd check that the wheel cylinders aren't sticking and that the brake shoe assembly has been replaced properly
I think it is time to find an accredited brake specialist . At the best with a hub it may be bad wheel bearings but I consider it a problem with the mechanics and their lack of commitment to fixing your problem
It sounds like the brake shoes are reversed or the wrong ones. Also may be faulty, or incorrectly installed brake hardwre. I'm assuming this problem did not happen until after the brake job? If it did, then you might have a different problem.
If no oil on the driver side, you have a locked up parking brake pivot. Follow the park brake cable to the inside plate of the rear wheels. on the outside, where the cable connects, look to see the position of the visible mechanism connected to the cable. It probably will not match the side that is not locked up. This is a very common problem; you need to replace the park brake pivot. Additionally, you are going to need to remove the other side axle shaft and get the leaking oil seal replaced. Replace the brake shoes if they have oil on them.
the drivers side rear brake shoes may be adjusted to tightly, so that immedatly when you step on the pedal, it locks up. try adjusting them in a bit first. Also, make sure that the wheel cyliner is the correct one, and it is not to big. i have not ever seen a proportioning valve problem on a cavalier.
