15. First insert the clip ends (A) to the pad pins (B), and then twist the clip into the caliper hole (C) to

stabilize.

16. Clean the mating surface of the brake disc and the inside of the wheel, then install the front wheels.

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

18. Add brake fluid as needed.

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

necessary.

20. Reinstall the front wheels, then test-drive the vehicle.

21. Check for leaks.

FRONT BRAKE DISC INSPECTION

NOTE:

Engagement of the brakes 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.

RUNOUT

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

AND SUPPORT POINTS ).

2. Remove the front wheels.

3. Remove the brake pads (see REPLACEMENT ).

4. Inspect the brake disc surface for damage and cracks. Clean the brake disc thoroughly, and remove all

rust.

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

brake disc securely against the hub.

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

the outer edge of the brake disc.

Brake disc runout:

Service limit: 0.04 mm (0.0016 in.)

7. If the brake disc is beyond the service limit for runout, refinish the brake disc with a commercially

available on-car brake lathe.

THICKNESS AND PARALLELISM

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

AND SUPPORT POINTS ).

2. Remove the front wheels.

3. Remove the brake pads (see REPLACEMENT ).

4. Using a micrometer, measure brake disc thickness at eight points, approximately 45 «apart and 10 mm

(3/8 in.) in from the outer edge of the brake disc. Replace the brake disc if the smallest measurement

is less than the max. refinishing limit.

Brake disc thickness:

Standard: 27.9-28.1 mm (1.10-1.11 in.)

Max. refinishing limit: 26.0 mm (1.02 in.)

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

5. If the smallest measurement is less than the max. refinishing limit, replace the brake disc (see

FRONT BRAKE DISC REPLACEMENT ).

6. If the brake disc is beyond the service limit for parallelism, refinish the brake disc with a

commercially available on-car brake lathe.

REFINISHING

1. Remove the brake caliper assembly (see FRONT BRAKE DISC REPLACEMENT ).

2. Install the brake lathe brackets (A) to the knuckle (B).

NOTE:

This is the maximum allowable difference between the thickness
measurements.

NOTE:

Refinish the brake disc with a commercially available on-car brake lathe.

NOTE:

Place two bolts (C) in the brackets before tightening the bolts (D).

4. Measure the brake disc runout, thickness, and parallelism.

Max. refinishing limit: 26.0 mm (1.02 in.)

FRONT BRAKE DISC REPLACEMENT

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

AND SUPPORT POINTS ).

2. Remove the front wheels.

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

NOTE:

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

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