Brake Pads

INSPECTION



See Figure 1

For proper inspection, the disc brake pads themselves must be removed. See following section for details.

If a squealing noise occurs from the front brakes while driving a 1986-88 Pick-Up or 4Runner, check the pad wear indicator. If there are traces of the indicator contacting the rotor (disc), the brake pad must be replaced.

REMOVAL & INSTALLATION



1975-83 2WD Pick-Up (Except C & C), 1975-88 4WD Pick-Up and 4Runner and 1975-88 Land Cruiser

See Figures 2 and 3

The front pads must be removed for wear inspection. It is not necessary to remove the caliper.


CAUTION
Brake shoes 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 any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

  1. Jack up the front of the truck, support it on jackstands, and remove the front wheel.
  2.  
  3. Pull out the two wire clips at the ends of the pad pins.
  4.  
  5. Pull out the pads and anti-rattle spring.
  6.  
  7. Remove the brake pads. On all 2WD Pick-ups and 1988 4WD Pick-ups and 4Runners, lift out the anti-squeal shims .
  8.  
  9. Check the pad thickness and replace the pads if they are less than 1mm thick. New pads measure approximately 9.6mm thick.
  10.  

This minimum thickness measurement may disagree with your state inspection laws.

  1. Check the pins for straightness and wear, and replace if necessary.
  2.  

To install:
  1. Attach a clear vinyl tube onto the bleeder plug on the brake cylinder, and insert the other end into a jar half filled with brake fluid. Bleed off a small amount of brake fluid.
  2.  
  3. Use a C-clamp or hammer handle and press the caliper pistons back into the housing.
  4.  

Never press the pistons into the caliper when the pads are out on both sides of the truck.

  1. On 2WD Pick-ups, install the anti-squeal shims so that the folded part will face the pad, and the arrows will face the direction of forward rotation. Lightly coat both sides of the shims with anti-squeak lubricant before installation.
  2.  
  3. On 1988 4WD Pick-ups and 4Runner, install the 4 anti-squeal shims so that the black shims are between the silver shims and the brake pad.
  4.  
  5. Install the brake pads. On 1988 models with the V6 engine, the pad with the wear indicator goes on the inside! Be very careful not to get grease or oil on the inner surfaces of the pads.
  6.  
  7. Install the anti-rattle spring.
  8.  
  9. Slide the 2 pad retaining pins through the caliper and pads and install the retaining clip.
  10.  
  11. Install the wheel and lower the truck. Bleed the brakes and road test the vehicle.
  12.

1975-83 2WD Pick-Up (C & C Only)
  1. Raise the front of the truck and support with safety stands. Remove the wheel.
  2.  
  3. Remove the cylinder guide plates, cylinder support springs and pad support plates.
  4.  
  5. With the outer brake pad still attached, lift the caliper up and away from the caliper mounting frame.
  6.  
  7. Pull out the anti-rattle spring and remove the outer pad from the caliper. Remove the inner pad from the mounting frame.
  8.  
  9. Check the pad thickness and replace the pads if they are less than 1mm thick. New pads measure approximately 9.6mm thick.
  10.  

This minimum thickness measurement may disagree with your state inspection laws.

To install:
  1. Attach a clear vinyl tube onto the bleeder plug on the brake cylinder, and insert the other end into a jar half filled with brake fluid. Bleed off a small amount of brake fluid.
  2.  
  3. Use a C-clamp or hammer handle and press the caliper piston back into the housing.
  4.  
  5. Install the inner pad. Position the outer pad in the caliper and install the anti-rattle spring.
  6.  
  7. Position the caliper and outer pad into the support frame.
  8.  
  9. Install the pad support plates and cylinder support springs. Install the cylinder guide plates and tighten the bolts to 29-44 ft. lbs.
  10.  
  11. Install the wheel and lower the truck. Bleed the brakes and road test the vehicle.
  12.  

1984-88 2WD Pick-Up w/FS17-Type Brake

See Figures 4 through 31

  1. Remove the hub cap and loosen the lug nuts.
  2.  
  3. Jack up the front of the truck and safely support it with jackstands.
  4.  
  5. Remove the lug nuts and the wheel.
  6.  
  7. Attach a clear vinyl tube onto the bleeder plug on the brake cylinder, and insert the other end into a jar half filled with brake fluid. Bleed off a small amount of brake fluid.
  8.  
  9. Remove the caliper slide pin on the sub-pin (lower) side.
  10.  
  11. Swivel the caliper up and away from the torque plate. Tie the caliper to a suspension member so its out of the way. Do not disconnect the brake line.
  12.  
  13. Lift the 2 brake pads out of the torque plate. Remove the anti-squeal shim.
  14.  
  15. Remove the 4 pad support plates. On 1986-88 trucks, pull the 2 pad wear indicator plates off the pads.
  16.  
  17. Check the pad thickness and replace the pads if they are less than 1mm thick. New pads measure approximately 9.6mm thick.
  18.  

This minimum thickness measurement may disagree with your state inspection laws.

To install:
  1. Install the 4 pad support plates into the torque plate.
  2.  
  3. Install a new pad wear indicator plate to the bottom of each pad.
  4.  
  5. Install the anti-squeal shim to the back of the outer pad and then position both pads into the torque plate.
  6.  


CAUTION
When installing new brake pads, make sure your hands are clean. Do not allow any grease or oil to touch the contact face of the pads or the brakes will not stop the truck properly!

  1. Use a C-clamp or hammer handle and press the caliper piston back into the housing.
  2.  

Never press the piston into the caliper when the pads are out on both sides of the truck.

  1. Untie the caliper and swivel it back into position over the torque plate so that the dust boot is not pinched. Install the slide pin and tighten it to 65 ft. lbs. (88 Nm).
  2.  
  3. Check the condition of the cylinder side bushing boot. Pull on it to relieve any air from the cylinder side pin mounting area. Check that the hole plug on the main pin side is there. Push on the center of the plug to relieve any air from the inner portion of the main pin.
  4.  
  5. Install the wheel and lower the truck. Bleed the brakes and road test the vehicle.
  6.
