Reassembly
5410 Type:
NOTE: For 2056 type reassembly procedures, see page 19-18.
o Never use an air hose or dry brush to clean brako assemblies.. Use an OSHA approved vacuum cleanerto avoid breathing brake dust.. Contaminated brake discs or pads reduce stopping abilhy.. when reusing the pads, always reinstall the brake pads in their original positions to pr€vent loss of braking €fficiency.
CAUTION:
. Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid do€s contaci the psint, wash it oft imme"diately with water.
. Clean all parts in brake fluid and air dry; blow out all passag€s whh comp.€ssed air.. Betore reassembling, check that all parts are free ol dust and othor toreign particlos.
. Replace parts wilh new ones whenever specified to do so.. Make sure no dirt or other toreign matt€r is allowed to contaminate the brake fluid.. Always use Genuine Honda DOT 3 Brake Fluid. Using a non.Honda brake tluid can cause corrosion and decresse thelife of th€ system.
NOTE:
. Coat the piston, piston seal, and caliper bore with clean brake fluid.. Replace all rubber parts with new ones whenever disassembled.

CAUTION:
. When connecting the brake lines. make sure
that there is no inte erence between the brake
lines and oth6r Parts.
r Be careful not to bend or damage the brake lines
when installing the master cylinder.
NOTE: lf replacing the master cylinder or brake
booster, check and adiust the pushrod clearance
be{ore installing the master cylinder (see page 19-221'
Fill the master cylinder reservoir, and bleed the
brake svstem (see Page 19-7).
After installation. check the brake pedal height and
brake pedal tree play (see page l9-5) and adjust if
necessary.

Master Cylinder/Brake Booster
Pushrod Glearance Adjustment
NOTEr
. The master cylinder pushrod-to-piston clearancemust be checked and adjustments made, if neces_sary, before installing the master cylinder.. ABS type is shown, conventional brake type is similar.
1. Set the special tool on the master cylinde. body; push
in the center shaft until the top of it contacts the endofthe secondary piston by turning the adjusting nut.
Without disturbing the center shaft's Dosition, installthe specialtool upside down on the booster.Install the master cylinder nuts, and tighten to thespecified torque.
Connect the booster in-line with a vacuum gauge O _
101 kPa (0 - 760 mmHg, 30 in.Hg) to the booster,sengine vacuum supply, and maintain an enginespeed that will deliver 66 kpa (500 mmHg, 20 in.Hg)vacuum.
With a feeler gauge. measure the clearance Detweenthe gauge body and the adjusting nut as shown.
Clearance: 0 - 0.4 mm {0 - 0.02 in)

NOTE: lf the clearance between the gauge bodyand adjusting nut is 0.4 mm (0.02 in), the pushrod-to-piston clearance is 0 mm. However, if the clear_ance between the gauge body and adjusting nut is0 mm, the pushrod-to-piston clearance is 0.4 mm(0.02 in) or more. Therefore, it must be adjusted andrechecked.
6. lf clearance is incorrect, loosen the star locknut, andturn the adjuster in or out to adjust.
NOTE;
. Adjust the clearance while the specified vacuumis applied to the booster.. Hold the clevis while adjusting.
Tighten the star locknut securely.

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.
