Q: How to replace brake pads on a Chevrolet C1500 and K1500?
A: Loosen the front wheel lug nuts, raise the front of the vehicle and support it securely on jackstands. Apply the parking brake. Remove the wheels. Remove about two-thirds of the fluid from the master cylinder reservoir because, as the pistons are pushed in for clearance to allow the pads to be removed, the fluid will be forced back into the reservoir. Work on one brake assembly at a time. Push the piston back into the bore to provide room for the new brake pads. A C-clamp can be used to accomplish this. Remove the C-clamp. Remove the two caliper mounting bolts. Lift the caliper off the disc and remove the outer pad. Pull the inner pad out of the caliper and remove it. Fasten the caliper out of the way with a piece of wire to prevent damage to the brake hose. Remove the mounting bolt seals, then use a scribe or similar tool to extract the rubber bushings from inside the caliper ears. Clean the caliper and mounting bolts and check them for corrosion and damage. Replace the bolts with new ones if they're significantly corroded or damaged. Inspect the Brake Disc carefully. If machining is necessary, follow the information to remove the disc. Begin reassembly by installing the new rubber bushings and seals in the caliper. Fill the space between the bushings with silicone grease. Position the inner pad, with the clip, in the caliper so the wear indicator is facing the rear of the caliper. Position the outer pad in the caliper so the tab at the bottom of the pad is engaged in the cutout in the caliper. Hold the caliper in position over the disc, push the mounting bolts through the bushings and thread them into the bracket. Tighten them to the torque listed in the specifications. Install the brake pads on the opposite wheel, then install the wheels and lower the vehicle. Add brake fluid to the reservoir until it's full. Pump the brakes several times to seat the pads against the disc, then check the fluid level again. Check the operation of the brakes before driving the vehicle in traffic. Try to avoid heavy brake applications until the brakes have been applied lightly several times to seat the pads.
