Brake Disc (Rotor)

Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Raise and safely support the vehicle.
  4.  
  5. Remove the tire and wheel assembly.
  6.  
  7. Install a C-clamp over the body of the brake caliper, with the C-clamp ends against the rear of the caliper body and the outboard disc brake pad.
  8.  
  9. Tighten the C-clamp until the caliper piston is compressed into the caliper bore enough to allow the caliper to slide past the brake rotor.
  10.  
  11. Remove the C-clamp.
    WARNING
    Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn cause a brake fluid leak.


    NOTE
    Do NOT disconnect the hydraulic brake flexible hose from the caliper.

  12.  
  13. Remove the brake caliper and the caliper mounting bracket as an assembly from the knuckle and support the assembly with heavy mechanic's wire, or equivalent. Ensure that there is no tension on the hydraulic brake flexible hose.
  14.  
  15. Matchmark the position of the brake rotor to the wheel studs.
  16.  
  17. Remove the brake rotor.
  18.  

To install:


WARNING
Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should be cleaned from the hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled Lateral Runout (LRO) of the brake rotor, which could lead to brake pulsation.

  1. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining.
  2.  
  3. Install the brake rotor to the hub/axle flange. Use the matchmark made prior to removal for proper orientation to the flange.
  4.  
  5. If the brake rotor was removed and installed as part of a brake system repair, measure the assembled LRO of the brake rotor to ensure optimum performance of the disc brakes.
    NOTE
    Brake rotor assembled LRO exceeding the maximum allowable specification can cause thickness variation to develop in the brake rotor over time, usually between 3,000-7,000 miles (4,800-11,300 km).


    NOTE
    Brake rotor thickness variation MUST be checked BEFORE checking for assembled LRO. Thickness variation exceeding the maximum acceptable level can cause brake pulsation.

  6.  
  7. Install the rotor secure and tighten the lug nuts star-pattern to specification, in order to properly secure the rotor.
  8.  
  9. If the brake rotor has been REFINISHED or REPLACED with a new rotor, mount a dial indicator, to the knuckle and position the indicator button so it contacts the brake rotor friction surface at a 90° angle, approximately 1 / 2  in. (13mm) from the outer edge of the rotor.
  10.  
  11. Measure and record the assembled LRO of the brake rotor.
  12.  
  13. Rotate the rotor until the lowest reading is displayed on the indicator dial, then set the dial to zero.
  14.  
  15. Rotate the rotor until the highest reading is displayed on the dial.
  16.  
  17. Mark the location of the high spot relative to the nearest wheel stud, or studs.
  18.  
  19. Measure and record the amount of LRO.
  20.  
  21. Compare the brake rotor assembled LRO to the specifications.
  22.  
  23. If the brake rotor assembled LRO is within specifications, install the brake caliper and depress the brake pedal several times to secure the rotor in place before removing the dial indicator and the lug nuts.
  24.  
  25. If the brake rotor assembled LRO exceeds the specification, refinish the rotor to ensure true parallelism.
  26.  
  27. After refinishing the rotor, measure and record the assembled LRO of the brake rotor.
  28.  
  29. If the brake rotor assembled LRO measurement is within specification, install the brake caliper and depress the brake pedal several times to secure the rotor in place before removing the dial indicator and the lug nuts.
  30.  
  31. Install the tire and wheel assembly. Tighten the wheel lug nuts to 100 ft. lbs. (136 Nm).
  32.  
  33. Lower the vehicle.
  34.  
  35. If the brake rotor was refinished or replaced, or if new brake pads were installed, burnish the pads and rotors as follows:
    1. Select a smooth road with little or no traffic.
    2.  
    3. Accelerate the vehicle to 30 mph (48 km/h).
      WARNING
      Use care to avoid overheating the brakes while performing this step.

    4.  
    5. Using moderate to firm pressure, apply the brakes to bring the vehicle to a stop. Do not allow the brakes to lock.
    6.  
    7. Repeat steps 2 and 3 until approximately 20 stops have been completed. Allow sufficient cooling periods between stops in order to properly burnish the brake pads and rotors.
    8.
