Honda Civic. Manual — part 333

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 (B), and tighten the wheel 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, 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:

Except Si model: 19.0 mm (0.75 in.)
Si model: 23.0 mm (0.91 in.)

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: Except Si model (see REPLACEMENT - EXCEPT

SI MODEL ), Si model (see REPLACEMENT - SI MODEL ).

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:

Except Si model: 20.9-21.1 mm (0.82-0.83 in.)
Si model: 24.9-25.1 mm (0.98-0.99 in.)

Max. refinishing limit:

Except Si model: 19.0 mm (0.75 in.)
Si model: 23.0 mm (0.91 in.)

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

NOTE:

If the brake disc is beyond the service limit for
refinishing, replace it (see KNUCKLE/HUB
REPLACEMENT ).

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

NOTE:

This is the maximum allowable difference between the
thickness measurements.

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.

FRONT BRAKE CALIPER OVERHAUL

EXCEPT SI MODEL

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

NOTE:

If the brake disc is beyond the service limit for
refinishing, replace it (see KNUCKLE/HUB
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 OSHA-approved vacuum
cleaner.

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.

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.

NOTE:

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