The brake rotors on the 2005 Pontiac GXP are the component that the brakes grab onto to bring the vehicle to a stop. The brake rotors sit on the hub assembly with the brake caliper slid over the top of the brake rotor. Every time the brakes are applied, the brake pads are compressed inward onto the brake rotor. Once the brake pads are applied to the brake rotor, the vehicle begins to slow down until it stops.
Instructions
- 1
Park the 2005 Pontiac GXP on a level even surface and set the emergency brake.
2Jack the front of the car up and place the jack stands behind each front tire under the frame rail of the car. Lower the car onto the jack stands. Make sure that the jack stands are securely underneath the cars frame rail.
3Move to the side of the car where you want to install the new rotor. Remove the tire with a lug wrench. Turn the lug nuts counter-clockwise to loosen and remove the lug nuts. Pull the tire off and set it to the side.
4Remove the two allen head bolts that hold the brake caliper in place over the brake rotor. Then slide a flat head screwdriver in between the brake caliper piston and the brake pad. Pry the brake pad forward to make room for the brake caliper to slide off of the brake rotor.
5Slide the brake caliper straight off of the top of the brake rotor. Do not let the brake caliper hang from the brake line. Position the brake caliper so that it is sitting on the front strut or axle.
6Slide the brake rotor off of the hub assembly. The brake rotor on the 2005 Pontiac GXP is not attached to anything and will slide straight off.
7Line the holes up on the new brake rotor and slide the new rotor onto the lugs until it stops. Slide the brake caliper back over the brake rotor and insert the brake caliper bolts back in place and tighten down.
8Put the tire back on and tighten the lug nuts down very tight. Jack the car up and remove the jack stands. Lower the car to the ground.
9Crank the engine and pump the brakes a couple of times to set the brakes to the new brake rotor.
