Adjustment



  1. Adjust the parking brake pedal stroke to 4-5 clicks fully depressed. Insert a deep socket wrench to rotate the adjusting nut and loosen the cable sufficiently. Then, return pedal.
  2.  
  3. Remove the wheels.
  4.  
  5. Using a lug nut, secure the rotor to hub to prevent it from tilting.
  6.  
  7. Remove the adjusting hole plug. Using a flat-bladed screwdriver, turn the adjuster clockwise until the rotor is locked. After locking, turn the adjuster in the opposite direction by 5 or 6 notches.
  8.  
  9. Rotate the rotor to make sure that there is no drag. Then install the adjusting hole plug.
  10.  

  1. After adjusting the clearance of rear shoes, with no drag on rear brake, adjust the cable as follows:
    1. Operate the pedal 10 or more times with a force of 490 N (110 lbs.).
    2.  
    3. Depress the pedal until a deep socket can be inserted. Insert the deep socket, and rotate the adjusting nut to adjust the pedal stroke.
      NOTE
      Do not reuse the adjusting nut.

    4.  
    5. When the parking brake pedal is operated with a force of 200 N (45 lbs.), make sure the stroke is 4-5 notches. (Check it by listening and counting the ratchet clicks.)
    6.  
    7. With the parking brake pedal completely returned, make sure there is no drag on the rear brake.
    8.  

  2.  
  3. Perform the parking brake break-in operation as follows: Safely, drive forward at approximately 40 km/h (25 mph) with the parking brake set with a force of approx. 200 N (45 lbs.) for about 30 seconds.
  4.  
  5. After the break-in operation, check the pedal stroke of parking brake. Readjust if necessary.
    NOTE
    To prevent lining from getting too hot, allow a cool off period of approximately 5 minutes after every break-in operation.
