Front Brake Pad 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.


NOTE: The illustrations show NISSIN type.

Inspection


1.Raise the front of the vehicle, and support it with safety stands in the proper locations.

2.Remove the front wheels.

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

Brake pad thickness: 
 Standard: 9.6-10.2 mm (0.38-0.40 in.) 
 Service limit: 1.6 mm (0.06 in.) 

Inner pad 

Outer pad 

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

Replacement


1.Raise the front of the vehicle, and support it with safety stands in the proper locations.

2.Remove the front wheels.

3.Remove the flange bolt (A) while holding the caliper pin (B) with a wrench. Be careful not to damage the pin boot, and pivot the caliper (C) up out of the way. Check the hose and pin boots for damage and deterioration.

NOTE: For AKEBONO type, do not need to hold the caliper pin with a wrench.

 

4.Remove the pad shims (A) and brake pads (B).

 

5.Remove the pad retainers (A).

 

6.Clean the caliper bracket (B) thoroughly; remove any rust, and check for grooves and cracks.

7.Check the brake disc for damage and cracks.

8.Apply a thin coat of Molykote M77 grease to the retainers on their mating surfaces (indicated by the arrows) against the caliper bracket.

9.Install the pad retainers. Wipe excess grease off the retainers. Keep grease off the brake discs and brake pads.

10.Apply a thin coat of Molykote M77 grease to the pad side of the shims (A), the back of the brake pads (B) and the other areas indicated by the arrows. Wipe excess grease off the pad shims and brake pads. Contaminated brake discs or brake pads reduce stopping ability. Keep grease and grease off the brake discs and brake pads.

 

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

12.Mount the brake caliper commercially available piston compressor (A) on the caliper body (B).

 

13.Press in the piston with the brake caliper piston compressor so the caliper will fit over the brake pads. Make sure the piston boot is in position to prevent damaging it when pivoting the caliper down.

NOTE: Be careful when in pressing in the piston brake fluid might overflow from the master cylinder's reservoir.

14.Remove the brake caliper piston compressor.

15.Pivot the caliper down into position. Install the flange bolt (A), and tighten it to the specified torque while holding the caliper pin (B), with a wrench. Be careful not to damage the pin boot.

NOTE: For AKEBONO type, do not need to hold the caliper pin with a wrench.

 

16.Press the brake pedal several times to make sure the brakes work.

NOTE: Engagement 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.

17.After installation, check for leaks at hose and line joints or connections, and retighten if necessary.
Test-drive the vehicle, then check for leaks.
