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 brake 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) with inner pad from the caliper bracket.

 

2.Remove the outer pad (A) and pad shim (B).

 

3.Remove the inner pad (A) from the caliper.

 

4.Remove the upper pad retainer (A) and the lower pad retainer. Clean the upper and lower retainers; remove any corrosion.

NOTE: The upper pad retainer and the lower pad retainer are different. During installation, make sure the pad retainers are in proper position.

 

5.Clean the caliper throughly; remove any rust, and check for grooves and cracks.

6.Check the brack disc for damage and cracks.

7.Apply Molykote M-77 grease to the pad retainers on their mateing surface against the caliper bracket (C). Wipe excess paste off the retainers. Contaminated brake discs and brake pads reduce stopping ability. Keep paste and grease off the brake discs and brake pads.

8.Install the retainers.

9.Apply Molykote M-77 grease to the pad shim (A), the back of the outer pad (B), and the other areas indicated by arrows. Wipe excess paste off the retainers. Contaminated brake discs and brake pads reduce stopping ability. Keep paste and grease off the brake discs and brake pads.

 

10.Install the outer pad and pad shim.

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

 

12.Apply Molykote M-77 grease to the piston edge on it mating surface against the inner pad (B), and areas in the inner pad indicated by arrows. Wipe excess paste off the retainers. Contaminated brake discs and brake pads reduce stopping ability. Keep paste and grease off the brake discs and brake pads.

13.Push the pad hold spring (C) into the piston, then install the inner pad with the indicator (D) on the lower side.

14.Install the caliper (A) and caliper bolts (B), and torque them to the specified torque while holding the pin (C). Be careful not to damage the pin boots.

 

15.Press the brake pedal several times to make sure the brakes work. Install the front wheel, then test-drive the vehicle.

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.

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