Front Brake Caliper
Reassembly (cont'd)
2056 Type:
. Never use an air hose or dry b.ush to clean brake assemblies.. Uso an OSHA approved vacuum cleansr to avoid breathing brake dust.. Contaminated brake discs or pads reduce stopping ability.t when reusing the pads, always r6instsll the brake pads in their original positioos to prevent loss ol braking efficiency.
CAUTION:
' Do not spill brake tluid or th€ vehicle; it m8y damage the paint; if brake fluid does contact the paint, wash it off imme-diately with water.
. Clean all parts in brake tluid and air dry; blow out all passages with compr63ed air.. Beforo reassembling, check that all parts are fr€e of dust and other foreign particles,. Replace parts with new ones whenevea specified to do so.. Make sure no dirt or other foreign matter is allowad to contaminato the brake fluid,' Always use Genuine Honda DOT 3 Brake Fluid. Using a non-Honda brake fluid can caus€ corrosior and decrease thelife ol the system.
NOTE:
. Coat the piston, piston seal, and caliper bore with clean brake fluid.. Replaceall rubber parts with new ones whenever disassembled.

r Be careful not to bend or damage the brake lines
when installing the master cylinder.
NOTE: lf replacing the master cylinder or brake

Brake Booster InsPection
FunctionalTest
1. With the engine stopped, depress the brake pedal
several times to deplete the vacuum reservoir, then
depress the pedal hard and hold it for 15 seconds lf
the pedal sinks' either the master cYlinder is
bypassing internally, or the brake system (master
cylinder. lines. modulator, proportioning control
valve, or caliPer) is ieaking.
2. Start the engine with the pedal depressed lf the
pedal sinks slightly, the vacuum booster is operating
normally. lf the pedal height does not vary, the
booster or check valve is faultY.
3. With the engine running. depress the brake pedal
lightly. Apply just enough pressure to hold back
automatic transmission creep. lf the brake pedal
sinks more than 25 mm (1.0 in.) in three minutes,
the master cvlinder is faulty. A slight change in
pedal height when the A'lC compressor cycles on
and off if normal. (The A/C compressor load
changes the vacuum available to the booster')
Leak Test
1. Depress the brake pedal with the engine running.
then stop the engine. lf the pedal height does not
vary while depressed for 30 seconds, the vacuum
booster is OK. lf the pedal rises. the booster is
faulty.
2, With the engine stopped, depress the brake pedal
several times using normal pressure When the
Dedal is first depressed, it should be low On con-
secutive applications, the pedal height should grad-
uallv rise. lf the pedal position does not vary, checK
the booster check valve.

Booster Check Valve Test
1. Disconnect the brake booster vacuum hose at the
booster.
2. Stan the engine and let it idle. There should be vac-
uum. lf no vacuum is available, the check valve is
not working properly. Replace the brake booster
vacuum hose and check valve, and retest.

Release the parking brake, and remove the calioersh ield.
CALIPER SHIELD
Remove the brake hose clamp bolt from the trailingarm first, then remove the two caliper mountingbolts and the caliper from the bracket.
CAUTION:
. Thoroughly clean the outside of the caliDer toprevent dust and dirt trom entering inside.. Support the calipor with a pieco of wire so thatit does not hang fuom the brake hose.

Using vernier calipers, measure the thickness ofeach brake pad lining. The measurement does notanclude the pad backing plate thickness.
Brake Pad Thickness:
Standard: 7.0 - 8.0 mm {0.28 - 0.31 in}Service Limit: 1.5 mm {0.06 in}
lf the pad thickness is less than the service limit,replace the pads and shims together as a set.

Clean the caliper thoroughly; remove any rust, and
check for grooves and cracks.
Check the brake disc for damage and cracks.
lvlake sure that the pad retainers are installed in
their correct positions.
PAD RETAINERS
Apply grease to the points indicated by the arrow in
the following drawing:
NOTE: Use the pad grease included in the pad set
or lMolykote M77 grease, and apply a thin coat of
grease evenly to the designated points.
. Piston end and inner pad contact surface
. Pad and caliper bracket contact surface
. Outer pad shim and outer pad contact surface
. Outer pad shim and caliper body contact surface
lnstall the brake pads and outer pad shim on the
caliper bracket. Install the inner pad with its wear
indicator facing downward.
@iwhen reusing the pads, always reinstall the
brake pads in iheil original posiiions lo prevont
loss ol braking efficiency
. Contaminaled brake discs or pads reduce stop-
ping ability. Keep grease off the discs and pads.

the inner pad by turning the piston back
CAUTION: Lubricate ths boot with rubber grease
to avoid twisting the piston boot. lf the piston boot
is twisted, back it out so it sits properly.

After installation. check for leaks at hose and line
joints and connections, and retighten if necessary.
Depress the brake pedal several times to make sure
the brakes work, then test-drive
NOTE: Engagement of the brake may requrre greater
pedal travel immediately after the brake pads have
been replaced as a set. Several light applications of
the brake pedal will restore the normal pedal travel.
Greater than normal pedal travel may damage the
