Rear 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 rear of the vehicle, and make sure it is securely supported. Remove the rear wheels.

2.Check the thickness of the inner (A) and outer pads (B). Do not include the thickness of the brake pad 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.Hold the pins (A) with a wrench, being careful not to damage the pin boots. Remove the caliper bolts (B) and remove the caliper (C) from the caliper bracket.

 


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.Install the pad retainers.

7.Apply Dow Corning Molykote M77 grease to both sides of the pad shims (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.

 

8.Install the brake pads and pad shims 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.

9.Push in the piston (A) so that the caliper will fit over the pads.Check the brake fluid level. The brake fluid may overflow if the reservoir is too full. Make sure that the piston boot is in position to prevent damaging it when installing the caliper.

 

10.Apply Dow Corning Molykote M77 grease to the piston edges (B) on their mating surfaces against the inner pad shim.

11.Install the brake caliper (C) and caliper bolts (D), and torque them to the specified torque while holding the pin (E). Be careful not to damage the pin boots.

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

NOTE: Engagement of the brake may require a greeter 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.
