Brake Calipers

Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Drain 2 / 3 of the brake fluid from the front reservoir. Use the bleeder screw at the front outlet port to drain the fluid. If equipped with anti-lock brakes, relieve the system pressure.
  4.  
  5. Raise and safely support the vehicle.
  6.  
  7. Remove the wheels.
  8.  
  9. Place a C-clamp on the caliper so the solid end contacts the back of the caliper and screw end contacts the metal part of the outboard brake pad.
  10.  
  11. Tighten the clamp until the caliper moves far enough to force the piston to the bottom of the piston bore. This will back the brake pads off of the rotor surface to facilitate the removal and installation of the caliper assembly.
  12.  
  13. Remove the C-clamp.
  14.  
  15. Remove both of the mounting bolts and lift the caliper off the rotor.
  16.  
  17. If the caliper is being removed, it is necessary to disconnect the brake fluid hose. Clean the brake fluid hose-to-caliper connection thoroughly. Remove the hose-to-caliper bolt. Cap or tape the open ends to keep dirt out. Discard the copper gaskets.

WARNING
If new caliper bolts are being installed, or if the original reason for repair was a drag/pull condition, check caliper bolt length before proceeding. Bolts must not have a shank length greater than 2.66 inches (67.6 mm).

  1. Connect the brake line to the caliper with new sealing washers and fitting bolt. Hand-tighten the fitting bolt.
  2.  
  3. Position the caliper into place over the rotor.
  4.  
  5. Coat the caliper mounting bolt with silicone grease and torque them to 11 ft. lbs. (15 Nm).
  6.  
  7. Position the brake line clear of all chassis components, untwisted and free of kinks. Torque the fitting bolt to 23 ft. lbs. (31 Nm).
  8.  
  9. Install the wheels.
  10.  
  11. Fill the master cylinder with fluid and bleed the brake system.
  12.  
  13. Before driving the vehicle, pump the brakes several times to seat the pads.
