Front Brake Pads Inspection and Replacement



Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.
  • Avoid breathing dust particles.
  • Never use an air hose or brush to clean brake assemblies. Use an appropriate vacuum cleaner.


Inspection


1.Raise the front of the vehicle, and make sure it is securely supported. Remove the front wheels.

2.Check the thickness of the inner pad (A) and outer pad (B). Do not include the thickness of the backing plate.

Brake pad thickness: 
 Standard: 8.5-9.5 mm (0.33-0.37 in.) 
 Service limit: 1.6 mm (0.06 in.) 

 

3.If the brake pad thickness is less than the service limit, replace all the pads as a set.

Replacement


1.Remove the bolt (A), and pivot the caliper (B) up out of the way. Check the hose and pin boots for damage and deterioration.

 

2.Remove the pad shims (A) and pads (B).

 

3.Remove the pad retainers (A).

 

4.Clean the caliper thoroughly; remove any rust, and check for grooves and cracks.

5.Check the brake disc for damage and cracks.

6.Apply Dow Corning Molykote M77 grease to the retainers on their mating surfaces against the caliper bracket.

7.Install the pad retainers. Wipe excess grease off the retainers. Contaminated brake discs and pads reduce stopping ability. Keep grease off the discs and pads.

8.Apply Dow Corning Molykote M77 or Daikalub 528D grease to both sides of the pad shim (A), the back of the pads (B), and the other areas indicated by the arrows.
Wipe excess grease off the shim. Contaminated brake discs and pads reduce stopping ability. Keep grease off the discs and pads.

 

9.Install the brake pads and pad shim correctly. Install the pads with the wear indicators (C) on the inside.
If you are reusing the pads, always reinstall the brake pads in their original positions to prevent a momentary loss of braking efficiency.

10.Push in the piston (A) so the caliper will fit over the pads. Make sure the piston boot is in position to prevent damaging it when pivoting the caliper down.

 

11.Pivot the caliper down into position. Being careful not to damage the pin boots, install the bolt (B), and tighten it to the specified torque.

12.Press the brake pedal several times to make sure the brake works, then test-drive.

NOTE: Engagement of the brake may require a greater pedal stroke immediately after the brake pads have been replaced as a set. Several applications of the brake pedal will restore the normal pedal stroke.

13.After installation, check for leaks at hose and line joints or connections, and retighten if necessary.
