For proper inspection, the disc brake cylinder (caliper) and the brake pads themselves must be removed. Refer to the following procedure for details.

If a squealing noise occurs from the front brakes while driving a 1982-85 Celica or Supra, check the pad wear indicator. If there are traces of the indicator contacting the rotor (disc), the brake pads must be replaced.

REMOVAL & INSTALLATION



1971-81 Models
  1. Remove the hub cap, if equipped, and loosen the lug nuts.
  2.  
  3. Raise the front of the vehicle with a jack and support it with stands beneath the chassis pads provided.
  4.  


CAUTION
Be sure that the car is securely supported. Do not support the car by the lower control arm.

  1. Remove the lug nuts and the wheel.
  2.  
  3. Unfasten the four clips which secure the caliper guides and remove the guides.
  4.  
  5. Remove the disc brake cylinder (caliper) assembly.
  6.  

If only the brake pads are to be replaced, do not disconnect the brake line. Just wire the cylinder out of the way.

  1. Remove the brake pads, pad guide plates, anti-rattle springs and the pad support plates.
  2.  
  3. Inspect the pads for wear. If the grooves are worn out of the pads, they will require replacement. Check the pad thickness against the specifications given in the Brake Specifications chart later in this section. Check all guides and springs for any wear or deformation.
  4.  
  5. Installation is in the reverse order of removal. Bleed the brakes if necessary.
