Hi I have my chevy lumina 98 and I was trying to change the back disk brakes the other day, I jacked up my car put my e-brake on, removed a tire and started to take the caliper off. There is only one bolt for the caliper and a pivot bolt. Your suppose to slip the brake up change the pads then slip it back down but after removing the first bold I couldn't get it to move period. Maybe because the e-Brake was on?

Also when im driving hear a clunking sort of noise when I hit bumps but when im on the breaks the noise is gone? loose caliper? (the noise is coming from the front.)

 

Hi Mike,

The E-brake is probably slowing you down. Jack it down,carefully chock the front wheels, then release the parking brake.

Jack slowly,using multiple jack stands.The calipers are self-adjusting, and therefore tight. Remove some brake fluid from the master cylinder, or if you're going to bleed the brakes anyway, release the bleeder screw, and attach a hose to the bleeder screw going into a pan or catch-basin of some kind.

Do NOT spill brake fluid. It eats paint very fast. If you do, wipe it off quickly, then wash it repeatedly with soapy water.

Be sure to loosen the pivot bolt a turn.Then push the caliper piston back into the caliper to release pressure on the pads. A vise grips or c-clamp should work. Once the pads aren't frozen, the caliper should slide up.

As to the clunking noise, a visual inspection of your front end is in order. Loose calipers should be obvious, but you could be dealing with bearings, bad shocks or struts, or a cracked driveaxle. How's the steering?f

 

I actually have just had the wheel bearings and ball joints done, the car need an alignment but besides that she steers pretty well. I will take a look at the caliper in the front hopefully thats the noise. As for the back brakes im going to bring it to a mechanic and get him to do the rotars aswell plus a safety check.
