Save yourself some money by changing the rear brake disks on your Mini Cooper S yourself. Brake disks, or rotors as they are also commonly called, may need changing if they have worn out or been damaged by worn, loose or missing brake pads. If your Mini Cooper's brakes are squeaking or grinding then it's worth taking a look at the rotors to make sure they're still in good shape, and then changing them if they're not.

Skill level:

Things you need

  • Jack
  • Jack stands
  • Socket set
  • Zip tie or string
  • Hex socket
  • New rotor

  1. 1

    Loosen the bolts on both rear wheels.

  2. 2

    Jack the car up and place on the jack stands.

  3. 3

    Remove the lug bolts and then remove both rear wheels.

  4. 4

    Remove the two bolts holding the brake caliper in place and swing it back. Secure it to a piece of the chassis using the coat hanger.

  5. 5

    Unscrew the hex bolt at the centre of the brake rotor. Remove the bolt and pull off the rotor.

  6. 6

    Replace the old rotor with the new one. Secure the new rotor in place with the hex screw.

  7. 7

    Remove the coat hanger and drop the caliper back into place. Secure it in place with the two bolts.

  8. 8

    Put the wheel back on and secure it with the lug bolts.

  9. 9

    Take the Mini down from the jack stands and then tighten the lug bolts to the correct specification.

Tips and warnings

  • A long wrench will help you get enough leverage to undo the lug bolts for the first time.
  • Double check all your work - the brakes are an essential safety system.
  • Never work under a car on a jack. Only work underneath a car when it is securely on jack stands.
