How do you remove the rear brakes on a 2003 Buick LeSabre?

Answer 1

If it's disk brakes, it's about like the front, except that it takes a lot of torque to get the caliper piston to go back in. It really is hard to get back in, once you do then your set. Use a large 8" or greater C-Clamp to compress the piston. Here is how: 1) Remove the back bolts holding the caliper assembly, loosen the top one first, but do not remove it yet. The bottom bolt does not come out--that's why it has a torx head; it's only removed for rotor replacement. 2) Remove the pads. 3) Loosen the bleeder screw so you don't send dirty fluid back through the ABS unit. 4) Use a spanner wrench to turn the piston back in to the bore. The piston can only be moved about 1 mm without damaging the emergency brake mechanism. The rotor screws in. Do not force the piston in using a C-clamp, etc. 5) After seating the piston put on the new pads. 5) When finished bleed each side until clean clear fluid comes out. 6) If possible bleed the front calipers too. Bleeding out older fluid helps length life of the calipers.
