Rear 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.


Inspection


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

2.Remove the rear 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: 8.3-9.4 mm (0.33-0.37 in.) 
 Service limit: 1.6 mm (0.06 in.) 

 

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

Replacement


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

2.Remove the rear wheels.

3.Remove the brake hose mounting bolt (A).

 

4.Remove the flange bolts (B) while holding respective caliper pin (C) with a wrench. Be careful not to damage the pin boot, and remove the caliper (D). Check the hose and pin boots for damage and deterioration.

NOTE: Do not twist the brake hose and the parking brake cable to prevent damage.

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

 

6.Remove the pad retainers (A).

 

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

8.Check the brake disc for damage and cracks.

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

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

11.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 off the brake discs and pads.

 

12.Install the brake pads and pad shims correctly. Install the brake pad with the wear indicator (C) on the bottom 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.

13.Rotate the caliper piston (A) clockwise into the cylinder, then align the cutout (B) in the piston with the tab (C) on the inner pad by turning the piston back. Lubricate the boot with rubber grease to avoid twisting the piston boot. If the piston boot is twisted, back it out so it is positioned properly.

NOTE: Be careful when moving the piston back in the caliper, brake fluid might overflow from the master cylinder's reservoir.

 

14.Install the caliper. Install the flange bolts (D), and tighten it to the specified torque while holding respective caliper pin with a wrench. Be careful not to damage the pin boots.

15.Install the brake hose mounting bolt (E).

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.
