Honda Civic. Manual — part 339

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 ).

2. Remove the rear wheels.
3. Remove the brake pads (see REAR BRAKE PAD INSPECTION AND

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: 8.9-9.1 mm (0.35-0.36 in.)
Max. refinishing limit: 8.0 mm (0.31 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 HUB BEARING UNIT
REPLACEMENT-DISC BRAKE TYPE ).

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.

REAR 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

NOTE:

If the brake disc is beyond the service limit for
refinishing, replace it (see HUB BEARING UNIT
REPLACEMENT-DISC BRAKE TYPE ).

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.

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 into 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 piston, piston seal groove, and caliper bore 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.
