Toyota Celica 1986-1993 Repair Guide

Brake Disc (Rotor)



  1. Loosen the front wheel lugs slightly, then raise and safely support the front of the car. Remove the front wheel(s) and temporarily attach the rotor disc with two of the wheel nuts.
  3. Unbolt and remove the torque plate from the steering knuckle.
  5. Remove the two wheel nuts and pull the disc from the axle hub.

To install:

  1. Position the new rotor disc onto the axle hub and reinstall the two wheel nuts temporarily.
  3. Install the torque plate onto the steering knuckle, torquing to specifications.
  5. Remove the wheel nuts and install the front wheels. Secure the wheel lugs. Before moving the vehicle, make sure to pump the brake pedal to seat the brake pads against the rotors.


Examine the disc. If it is worn, warped or scored, it must be replaced. Check the thickness of the disc against the specifications given in the Brake Specifications Chart. If it is not within specifications, replace it. Use a micrometer to measure the thickness.

The disc run-out should be measured before the disc is removed and again, after the disc is installed. Use a dial indicator mounted on a magnet type stand (attached to the shock absorber shaft) to determine runout. Position the dial so the stylus is 10mm from the outer edge of the rotor disc. If runout exceeds the specification, replace the disc.
