  Q: How to replace the front brake pads on Buick Terraza?

  A:

  Inspect the brake master cylinder reservoir fluid level before starting. Drain fluid from the tank until the mark reaches the midpoint between the highest and lowest operating ranges. Lift the vehicle and take off the wheel after your support. Secure the rotor with wheel nuts before applying a c-clamp on top of the brake caliper and tightening until the piston moves into the bore so the caliper can slide away from the rotor. Support the brake caliper by using mechanic's wire while keeping the hydraulic flexible hose safe. Uninstall the c-clamp along with the brake caliper guide. Rise the brake caliper to see the brake pads. Remove both pads with the retaining screws from the bracket base. Before pressing the piston use wood or the old Brake Pad to block the bore between the c-clamp and Brake Caliper Piston to shield from damage. Then press the piston to bottom using the c-clamp. Check the brake caliper guide pin boots alongside the Brake Caliper Piston boot for tearing, cracking, leakage, or weakening so you can switch out defective parts right away. Look at the brake caliper guide pins for damage then replace them with fresh sections when needed. Wipe off the boot surface with denatured alcohol before adding replacement brake pads and push the piston into position using a c-clamp while shielding it with a block. Fit the two Brake Pad retainers onto the caliper bracket so that the wear sensor stays behind the outer pad during forward wheel motion before placing the brake pads on top of them. Use high temperature brake silicone lube to lubricate the guide pin and boot of the caliper system before placing the caliper pads. Tighten the lower caliper guide pin to 54 nm using a torque wrench after it fits on the brake pads. Replace the two rotor wheel nuts, put on the wheel and tire, make the vehicle sit lower, and supply new brake fluid to reach the right amount. Brake the pedal most of the way until it stays firm enough to work with before finishing the pad and rotor surfaces.

  Q: How to replace the rear brake pads (RPO Codes J65, JL9) on Buick Terraza?

  A:

  Check the brake master cylinder reservoir fluid level before starting rear Brake Pad replacement for rpo codes j65 and jl9. Check the master cylinder fluid level to determine whether fluid removal is needed; simply maintain the same level if it sits at midpoint yet increase removal when the level exceeds midpoint. Levitate the vehicle before removing the tire along with its wheel assembly. Unclamp the Wheel Speed Sensor (WSS) harness from the lower Control Arm and both upper and lower caliper bolts need removal from the caliper. Use heavy mechanic's wire to support the brake caliper before removing it from the bracket while keeping the hydraulic flexible brake hose connected to its bracket without any disconnection. First detach both inboard and outboard pads from the Brake Caliper Bracket before inspecting the guide boot assembly while also cleaning pad hardware surfaces with replacement of clips and piston boot when needed. Insert the spanner-type wrench (Mac® Tools DBC 25 C 2500 MA Disc Brake Caliper Tool Set or equivalent tool) and turn the Brake Caliper Piston clockwise until it reaches the brake caliper bore. Position the indents on the piston face to align with the pin located at the Brake Pad retainer's back then install all pads starting with the Brake Pad retainers into the Brake Caliper Bracket while placing the pad with the metallic wear sensor on the inboard side. Attach the caliper onto the bracket while checking if bracket guide boots remain intact then secure the brake caliper bolts at 34 nm (25 ft. Lbs. Torque). Install the tire and wheel assembly next before lowering the vehicle while re-clamping the wss harness to the lower Control Arm. During engine off position apply the brake pedal to 2/3 of its possible movement distance then slowly release it for multiple times until the brake caliper pistons and pads achieve complete pad-to-rotor contact. Complete the brake master cylinder reservoir while maintaining appropriate fluid level and execute pad and rotor burnishing.
