3. 4 WHEEL DRUM IT MAKES A DIFFERANCE ALSO IF IT'S 4 WHEEL DRIVE. LET ME KNOW, THEN I CAN ANSWER THAT QUESTION VERY EASILY !! BEN
Will require more specifics, what part you want to fix in the rear brakes?
If it is a Toyota, they do not know how to fix the squeaking brakes either. Even after replacing all the pads and machining the rotors and rear drums
what type of rear brakes does a chevy malibu require
Check the LPV (Load proportioning valve), if fitted. It controls the amount of rear vs front braking under "heavy" loads, if faulty it will cause rear lock up. Another thing to check is that front brakes have been bled, and the front brake circuit is working at all.
Estimate Front one side $380.00 Estimate Rear one side disc brakes $285.00
If your brakes are ineffective, you have a problem, part of that problem is that your truck is 23 years old. Why don't you change the fluid, replace the front pads and rear shoes. Replace the front rotors and rear drums. Inspect the rubber brake lines as they may be collapsing. Replace the master cylinder. Do all this if it is all necessary and I bet you have good brakes again. Fix the problem or problems and you will not have ineffective brakes.
The rear brakes on a 1989 jeep should be self adjusting. Tear the drums off and fix the seized or broken hardware.
www.parktool.com has a nice walk-through, as well as www.sheldonbrown.com
the brakes were not fixed properly some part is installed wrong
If the rear wheel brakes are locking up on a vehicle they should be thoroughly checked. The master cylinder may need to be replaced on the car.
that depends greatly on what is wrong with them.
More information: I went in because I was having electrical issues which they could not fix but insisted my front brakes are at 20% and rear brakes are at 0%.
