ok as the subject says my rear brakes a locking, i changed the wheel cylinders and the drums recently and it still does it. It mostly locks up when i am going slow like in a parking lot and i want to stop, and usually only one wheel locks, not always the same one but one if the back wheels lock. Therefore i get absolutly no "nosedive" when i slam on the brakes i get the complete opposite, the back end sinks down. This is extremely annoying and also very unsafe as my braking ability is greatly reduced. How the hell do i fix this???

Did you replace all of the drum brake hardware when you changed the wheel cylinder out??

Are the rear brakes adjusted properly. Put the rear of the car up on jackstands. With the wheels on, rotate them as if the car was moving forward. They should spin freely with no resistance. Now spin the wheel in the opposite direction, they should spin about 2 revolutions and then stop.

what about cables and stuff like that? could they be causeing the problem?

ok i think the rear might be adjusted a little tight but that is because my brake pedal has to move in a lot before it actually does anything. I have to push it in half way before anythign happens and then when i get half way the pedal is VERY sencitive, could it be the front that is too loose???

My rear wheels were just doing this. It was fixed by replacing the brakes with new ones. They were worn down real bad and the drum was worn so smooth it looked like a mirror (not a good thing). After all the new stuff was put on they stopped grabbing, brake better, and my ebrake no longer need to be pulled almost to it's limit before it catches.

If the pedal goes halfway with no brakes your problem is probably somewhere in the lines or the master cylinder. Are you sure that all of the air is out of the brake lines?? Is the master cylinder full?

yes i am positive all the air is out i bled the lines with my shop class techer at the begining of the summer when i replaced the rear brake lines

 

[Brad91Z]

Ok then I would just take apart the rear brakes and see if anything needs to be replaced.

Take your shoes out, and chamfer the ends of the shoe. Whats happening is only the end of the shoe is catching the drum, versus the shoe "resting" inside of the whole drum. So its putting too much pressure on one spot of the drum. If youve ever looked at one of your old shoes, you'd notice how the edges were already worn down from it breaking in on its own.

Hope this made sense
