With the caliper off the disk assembly -- you can use a big C-clamp to compress the piston in. also if a C-clamp is not around, you can simply loosen the 'zerk' fitting ( the bleeder ) and push the piston hard by hand. ( note: oil will shoot out of bleeder, so put a rag over it to protect your eyes and brake parts ) -- also make sure when you put it all back together that you bleed the brake lines of all air.

I have 2003 gallant, Islammed on the brakes really hard, tried to drive the car from that spot, go in gear but wouldn't move, front wheels roll, rear wheels are locked up.


If rear brakes are drum-type it is possible the shoes are jammed on the drums. They are normally retracted from there by springs, but if there is breakage or corrosion they can jam in place. One place corrosion occurs is in the wheel brake cylinders, so then the pistons do not return properly,

The same can happen with disc brakes as the pads are normally pulled back after application, just a little, by the springiness of the rubber parts on the pistons. So if there is corrosion in the calipers the pistons can stick.

Then, if disc brake pads are worn right down, I have heard of cases where the piston popped right out of the caliper on heavy braking, or else turned a bit sideways and jammed on. It should never happen, but apparently did.

If disc brakes you should be able to see this when the wheel is off. The calipers can then be removed. If drum brakes try hammering on the outside rim of the drums, this way and that, to get enough de-jamming to get the drums off.

Where r the bleeders on rear brakes for 1994 pontiac bonneville


If they are disc brakes, the bleeder valve will be on the brake caliper. If they are drum brakes, look on the back side of the brake backing plate. The bleed valve will be on the brake wheel cylinder. The valves probably have a little protective rubber boot on them.

How do I change the rear brake pads on a 2005 Pontiac Bonneville?


remove the caliper bolt, swivel the caliper up and slide off the rod. To push the caliper piston in to accommodate the new pads, you must get the tool to TWIST the piston in while slightly pressing the piston. Check with your local Murrays, Auto Zone for the tool loaner program. Gm W-Body rear caliper tool. Good luck
