Change The Rear Brake Rotors On A Mini Cooper

Improve braking by replacing the rear rotors on your Mini Cooper.

The Mini Cooper is a small, front-wheel drive economy car that is manufactured by BMW. The Mini Cooper comes standard with disc brakes on the front and rear wheels. Disc brake pads are pressed against the brake rotor to slow the vehicle’s momentum when the brake pedal is pushed. This action creates friction which will eventually wear the brake rotors thin, which necessitates their replacement for safe braking action.

Instructions

1. Loosen the lug nuts on each rear wheel with a lug wrench. Jack up the rear of your Mini with a hydraulic floor jack until its wheels are off the ground. Place a jack stand under each frame rail at the rear of the car. Lower the floor jack. Finish removing the lug nuts and remove the rear wheels.

2. Pull the brake sensor connector from the brake caliper and push it aside. Remove the caliper retaining bolts from the back side of the caliper with a socket and ratchet in a counterclockwise direction. Place the bolts aside. Pull the caliper straight off the brake rotor and hang it to the rear suspension strut with a bungee cord so it is out of the way.

3. Remove the bolts from the brake caliper bracket with a socket and ratchet and place them aside. Pull the caliper straight off the rotor and place it to the side.

4. Remove the single bolt that attaches the rotor to the wheel hub with a socket and ratchet. Rap the rotor with a rubber mallet from the back side to loosen it from the wheel hub and remove it from the vehicle. Push a new rotor onto the wheel hub and tighten the retaining bolt in a clockwise direction.

5. Slide the caliper bracket back over the new rotor and tighten the retaining bolts. Remove the bungee cord from the caliper and place it over the bracket. Tighten the caliper retaining bolts. Push the brake sensor connector back into the caliper until it is fully seated.

6. Repeat steps 2 through 5 to replace the other rear rotor. Replace the rear wheels and tighten the lug nuts. Remove the jack stands from under the car and remove the floor jack. Tighten the lug nuts in a criss-cross fashion. Depress the brake pedal a few times before driving the car to re-seat the brake pads against the rotors.
