Brake Pads

Print


CAUTION
Brake pads and shoes may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from brake surfaces! When cleaning brakes, use commercially available brake cleaning fluids

INSPECTION



The rear brake pads may be inspected without removal. With the rear end elevated and supported, remove the wheel(s).

View the inner and outer pads through the cut-out in the center of the caliper. Remember to look at the thickness of the pad friction material (the part that actually presses on the disc) rather than the thickness of the backing plate which does not change with wear.

Remember that you are looking at the profile of the pad, not the whole thing. Brake pads can wear on a taper which may not be visible through the window. It is also not possible to check the contact surface for cracking or scoring from this position. This quick check can be helpful only as a reference; detailed inspection requires pad removal.

REMOVAL & INSTALLATION



See Figures 1 through 5

We recommend replacement of the disc brake pads in axle sets for added safety and reliability

  1. Raise and safely support the rear of the vehicle.
  2.  
  3. Remove the wheel and temporarily fasten the rotor in position with the lug nuts.
  4.  
  5. Check the pad thickness by looking through the center hole provided at the top of the caliper. Minimum thickness should be 0.039 inch (1mm).
  6.  
  7. Open the bleeder screw on the caliper and bleed off a small amount of brake fluid.
  8.  
  9. Disconnect the clip that attaches the parking brake cable. Pull the cable from the brake cable bracket at the caliper.

  1. Remove the lower (closer to the ground) caliper mounting bolt. Pivot the caliper upward on the upper mounting bolt. Loosen the upper bolt slightly if required.
  2.  
  3. Take note of the position of the brake pads and mounting hardware while removing them. Remove the two brake pads, the two anti-squeal shims, two anti-rattle springs. pad support plate and two pad guide plates. Disassemble and assemble one side at a time so that the other side can be use for reference.
  4.  

To install:
  1. Check the rotor thickness and runout. Service as required. Assemble the brake pads in the support bracket in the reverse order of removal.
  2.  


WARNING
The caliper piston must be turned clockwise to retract it back into the caliper bore. Special Toyota tool SST 09719-14020 (09719-00020) or the equivalent is required

Do not attempt to push the caliper into the caliper bore otherwise damage to the parking brake adjuster will occur

  1. Turn the caliper piston clockwise, back into the caliper bore.
  2.  
  3. Lower the caliper and fit the brake pad protrusion (rear of inner pad) into the stopper groove in the caliper piston. Align as required.
  4.

  1. Finish lowering the caliper, taking care not to wedge the boot between the metal of the support bracket and caliper. Install the lower mounting bolt, then tighten the mounting bolts to 14 ft. lbs. (19 Nm).
  2.  
  3. Connect the parking brake cable. Adjust the parking brake by pulling and releasing the apply lever.
  4.  
  5. Install the rear wheel. Lower the vehicle. Fill the master cylinder and bleed the brake system.
