How does one change the front brake pads on a 1993 Chevy C-2500?

Answer 1

Jack up the front end, put stands or blocks under the vehicle. Remove the wheels. Remove the two bolts that hold the caliper to the mounting plate. Not that GM vehicles use an Allen wrench to turn the bolts. The bolts may be difficult to remove once they're turned completely out.

Remember how the brake pads were installed so that you can put the new ones back the same way. Check the rotors for wear and/or warping. Many of the rotors for that vintage vehicle just pull off especially for 4WD, some are bolted on and you'll have to figure out how to remove the rotor. The rotor should be surfaced if possible or replaced if it's too far gone to surface.

Clean the slide surfaces of the caliper if appropriate, push the caliper piston back in, either using the specialty tool or a C-clamp if you can do that without causing damage. Clean any packing or other oil from the rotor. Put the rotor and caliper with brakes back into place and re-attach the Allen bolts. Make certain that they are tight, since that's your brakes we're talking about here.

Good luck. It's a very satisfying job to complete yourself.

As always with brakes, test them at low speed before trusting them.
