Buick 19152705 Brake Pad

To replace the brake pads, start by removing the brake fluid reservoir cover and siphoning off about two-thirds of the fluid into a container for disposal. Loosen the wheel lug nuts, raise the front of the vehicle, and secure it on jackstands. Apply the parking brake and block the rear wheels. Remove the front wheel and reinstall two lug nuts to hold the rotor in place. Work on one brake assembly at a time. Inspect the rotor carefully and machine if necessary. Push the piston back into the bore using a pry bar or C-clamp while ensuring the fluid in the master cylinder doesn't overflow. For pad replacement, follow these steps: Use a no.50 Torx bit to remove the two caliper mounting bolts. Remove the inner pad by snapping it out of the piston, and the outer pad by bending the tabs straight and dislodging it from the caliper with a hammer. Inspect caliper bolts, bushings, and piston boot. Snap the inner pad retainer spring into the new pad and lubricate contact surfaces with white lithium-base grease. Place the pads in position, snap the inner pad into the piston, and secure the outer pad by bending the tabs over. When reinstalling the caliper, tighten the mounting bolts to specified torque. After completion, depress the brake pedal firmly a few times to bring the pads into contact with the rotor.
