Specifications)

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, refinish the brake disc with an on-

car brake lathe. The Kwik-Lathe produced by Kwik-Way Manufacturing Co.
and the "Front Brake Disc Lathe" offered by Snap-on Tools Co. are approved
for this operation.

Max. refinishing limit: 21.0 mm (0.83 in.)

THICKNESS AND PARALLELISM

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

locations, refer to the VEHICLE LIFT .

NOTE:

If the brake disc is beyond the service limit for
refinishing, replace it, refer to the
KNUCKLE/HUB/WHEEL BEARING REPLACEMENT .

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

2. Remove the front wheels.
3. Remove the brake pads (see REPLACEMENT ).
4. Using a micrometer, measure the brake disc thickness at eight points, about 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: 22.9-23.1 mm (0.90-0.91 in.)

Max. refinishing limit: 21.0 mm (0.83 in.)

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

5. If the brake disc is beyond the service limit for parallelism, refinish the brake

disc with an on-car brake lathe. The Kwik-Lathe produced by Kwik-Way
Manufacturing Co. and the "Front Brake Disc Lathe" offered by Snap-on Tools
Co. are approved for this operation.

NOTE:

This is the maximum allowable difference between the
thickness measurements.

NOTE:

If the brake disc is beyond the service limit for
refinishing, replace it, refer to the

FRONT BRAKE CALIPER OVERHAUL

Remove, disassemble, inspect, reassemble, and install the caliper, and note these
items:

Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid
gets on the paint, wash it off immediately with water.

To prevent dripping brake fluid, cover disconnected hose joints with rags or
shop towels.

Clean all parts in brake fluid and air dry; blow out all passages with
compressed air.

Before reassembling, check that all parts are free of dirt and other foreign
particles.

Replace parts with new ones as specified in the illustration.

Make sure no dirt or other foreign matter gets in the brake fluid.

Make sure no grease or oil gets on the brake discs or pads.

When reusing brake pads, always reinstall them in their original positions to
prevent loss of braking efficiency.

KNUCKLE/HUB/WHEEL BEARING REPLACEMENT .

CAUTION: 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.

NOTE:

Make sure that the caliper pins are installed correctly.
Upper caliper pin B and lower caliper pin A are different. If
the caliper pins are installed in the wrong location, it will
cause vibration, uneven or rapid brake pad wear, and
possibly uneven tire wear.

Do not reuse drained brake fluid. Use only clean Honda DOT 3 Brake Fluid
from an unopened container. Using a non-Honda brake fluid can cause
corrosion and shorten the life of the system.

Do not mix different brands of brake fluid as they may not be compatible.

Coat the pistons, piston seal grooves, and caliper bores with clean brake fluid.

Replace all rubber parts with new ones whenever disassembled.

After installing the caliper, check the brake hose and line for leaks,
interference, and twisting.
