Saturn 21990460 Brake Pad

Remove the cap from the brake fluid reservoir, then loosen the wheel lug nuts, raise the end of the vehicle you're working on, and support it securely on jack stands while blocking the wheels at the opposite end. Remove the wheels and work on one brake assembly at a time, using the assembled brake for reference if necessary. Inspect the brake disc carefully; if machining is necessary, remove the disc to also take out the pads. Push the piston back into its bore to create space for the new brake pads, using a large C-clamp between the outer brake pad and the back of the caliper to compress the piston slowly. As the piston is depressed, ensure the fluid in the master cylinder does not overflow, siphoning off some if necessary. Wash the brake assembly with brake cleaner before disassembling, then remove the lower caliper bolt; to detach the caliper completely, remove both caliper bolts but do not let the caliper hang by the brake hose. Secure the caliper with a piece of wire, remove the inner and outer brake pads, and check the support plates for wear, replacing them if necessary. Lubricate the sliding pins with high-temperature grease after cleaning and replace any damaged rubber boots. Install the cleaned support plates, the new outer and inner pads, and the sliding pins, then swing the caliper into place, replacing and tightening both bolts to the specified torque. If there is difficulty sliding the caliper assembly over the disc, push the piston farther into the bore using the C-clamp. After completing the job, firmly depress the brake pedal a few times to bring the pads into contact with the disc, check the brake fluid level and add some if necessary, and carefully check the operation of the brakes before placing the vehicle into normal service.
