  Q: How to replace the front disc brake pads on GMC Envoy?

  A:

  Start the Brake Pad replacement by checking your brake master cylinder reservoir fluid level. If it stands higher than the middle mark between the acceptable range, use a brake fluid extractor to lower it until it reaches the middle position. Lift the vehicle and take off the tire and wheel unit. Press down the brake caliper pistons by pushing a large c-clamp over the brake caliper case onto the back of the outer Brake Pad until the pistons create room to move the caliper away from the rotor. Take out the caliper by removing first the c-clamp then loosening the bolt that secures the guide pin and moving the caliper upward until it stops. Clean the brake caliper with denatured alcohol before you remove its inboard and outboard brake pads. Keep the Brake Pad retaining clips from the brake caliper mounting bracket for later use. New brake pads must go with fresh retaining clips during replacement. Place Brake Pad retaining clips on the brake caliper mounting bracket first before positioning the new brake pads properly. Keep the spreader springs from getting highly warped during this process. Place the brake caliper back where it belongs. After that, tighten the lower brake caliper guide pin bolt to 64 n.m (47 lb ft). Reposition the wheel and tire parts before letting the car down and topping up the brake fluid tank. Press the brake pedal gently but firmly to allow the brake pads to rest in place before using Brake Pad burnishing.

  Q: How to replace the rear disc brake pads on GMC Envoy?

  A:

  Assess the brake fluid level before starting the replacement. If the brake fluid in the brake master cylinder reservoir stands at mid-point between high and low marks no fluid needs removal. If it exceeds that level draw the fluid down to mid-point using a brake fluid extractor. Lift up your vehicle before taking off the tire and wheel unit. Obtain the Brake Caliper Piston into the proper position by tightening a c-clamp on the brake caliper housing to push the piston through the Brake Pad and off the rotor surface. Push the brake caliper down by removing its upper mounting bolt. Then lower the brake caliper to a stopping point and take out the brake pads alongside their retaining clips both at the mounting bracket and within the brake caliper. Wipe down and let the brake caliper mounting bracket air dry using filtered non-lubricated compressed air along with denatured alcohol. To install new brake pads choose fresh Brake Pad retaining clips and attach them to the brake caliper mounting bracket. Afterward place the brake pads accordingly while making sure the Brake Pad retaining clip fits inside the brake caliper housing. Assemble the clip onto the brake caliper first and lift the rear brake caliper towards position. Finally torque the upper brake caliper bolt to 31 n.m (23 lb ft). Reposition the wheel and tire then bring down the vehicle before refilling the brake master cylinder. Slowly push the Brake Pedal down with force to make the brake pads properly fit and let them wear out their new surface.
