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

9. Check the brake disc/drum for damage and cracks.

10. Apply M-77 assembly paste (P/N 08798-9010) to the retainers on their mating surfaces against the

caliper bracket indicated by arrows.

11. Install the pad retainers. Wipe excess assembly paste off the retainers. Contaminated brake discs and

pads reduce stopping ability. Keep assembly paste off the discs and pads.

12. Install the pad retainers.

13. Apply M-77 assembly paste (P/N 08798-9010) to the pad side of the shims (A), and back of the brake

pads (B) and the other areas indicated by the arrows. Wipe excess assembly paste off the pad shims
and brake pads. Contaminated brake discs or pads reduce stopping ability. Keep assembly paste off
the discs and pads.

indicator (C) facing on top. If you are reusing the brake pads, always reinstall the brake pads in their
original positions to prevent a momentary loss of braking efficiency.

15. Push in the piston (A) so the caliper will fit over the brake pads. Make sure the piston boot is in

position to prevent damaging it when installing the caliper.

16. Apply M-77 assembly paste (P/N 08798-9010) to the piston edges (B) on their mating surfaces

against the inner pad shim.

17. Install the brake caliper (C).

18. Install the caliper bolts, and torque them to the specified torque while holding the caliper pins (D)

with a wrench being careful not to damage the pin boot.

19. Clean the mating surface of the brake disc/drum and the inside of the wheel, then install the rear

wheels.

20. Press the brake pedal several times to make sure the brakes work, then road-test the vehicle.

21. Add brake fluid as needed.

22. After installation, check for leaks at the hose and line joints and connections, and retighten if

necessary.

REAR BRAKE DISC INSPECTION

RUNOUT

NOTE:

Be careful when pushing in the caliper, brake fluid might overflow from
the master cylinder’s reservoir.

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.

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

SUPPORT POINTS ).

2. Remove the rear wheels.

3. Remove the brake pads (see REAR BRAKE PAD INSPECTION AND REPLACEMENT ).

4. Inspect the brake disc/drum surface for damage and cracks. Clean the brake disc/drum thoroughly,

and remove all rust.

5. Install suitable flat washers (A) and wheel nuts (B), and tighten the wheel nuts to the specified torque

to hold the brake disc/drum securely against the hub.

6. Set the dial gauge up against the brake disc/drum as shown, and measure the runout at 10 mm (3/8 in.)

from the outer edge of the brake disc/drum.

Brake disc/drum runout:

Service limit: 0.04 mm (0.0016 in.)

7. If the disc is beyond the service limit, refinish the brake disc/drum with a commercially available on-

car brake lathe.

Max. refinishing limit: 14.0 mm (0.55 in.)

THICKNESS AND PARALLELISM

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

SUPPORT POINTS ).

NOTE:

If the brake disc/drum is beyond the service limit for refinishing,
replace it (see REAR BRAKE DISC REPLACEMENT ).

A new disc should be refinished if its runout is greater than 0.04
mm (0.0016 in.).

2. Remove the rear wheels.

3. Remove the brake pads (see REAR BRAKE PAD INSPECTION AND REPLACEMENT ).

4. Using a micrometer (A), measure disc/drum thickness at eight points, about 45 «apart and 10 mm (3/8

in.) in from the outer edge of the brake disc/drum. Replace the brake disc if the smallest measurement
is less than the max. refinishing limit.

Brake disc/drum thickness:

Standard: 15.9-16.1 mm (0.625-0.634 in.)

Max. refinishing limit: 14.0 mm (0.55 in.)

Brake disc/drum parallelism: 0.015 mm (0.0006 in.) max.

5. If the disc is beyond the service limit for parallelism, refinish the brake disc/drum with a

commercially available on-car brake lathe.

REAR BRAKE DISC REPLACEMENT

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

SUPPORT POINTS ).

2. Remove the rear wheel.

3. Remove the brake caliper bracket mounting bolts (A), and remove the caliper assembly (B) from the

knuckle. To prevent damage to the caliper assembly or brake hose, use a short piece of wire to hang

NOTE:

This is the maximum allowable difference between the thickness
measurements.

NOTE:

If the brake disc/drum is beyond the service limit for refinishing,
replace it (see REAR BRAKE DISC REPLACEMENT ).
