Inspection and Adiustment
Brake System Rubber Parts and Brake Booster
@ Brake Boost€r
Check brake operation by applying the brakes.
lf the brakes do not work properly, check the brake
booster. Replace the brake booster as an assembly if it
does not work properly or if there are signs of leakage
@ Piston cup and Pre3sure cup Inspection
. Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leakage,
Replace the master cylinder as an assembly if the
pedal does not work properly or if there is damage
or signs of fluid leakage.
. Check for a difference in brake pedal stroke betlveen
quick and slow brake applications, Replace the mas-
ter cylinder if there is a difference in pedal stroke.
O Brake Hoses
Visually check for damage or signs of fluid leakage.
Replace the brake hose with a new one if it is darnaged
or leaking.
@ Caliper PBton Seal and Pkton Boots
Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leakage.
lf the pedal does not operate properly, the brakes drag.
or there is damage or signs of fluid leakage, disassem-
ble and inspect the brake caliper. Replace the boots
and seals with new ones whenever the brake caliper is
disassembled.

Bleeding
CAUTION:
. Oo not reuse the drsined fluid,
. Always use Genuine Honda DOT 3 Brake Fluid. Using
a non-Honda brake fluid can cause corrosion and
decrease the lile of the system,
a Make sure no dirt or other foreign matt€t is allowed
to contaminate the brske fluid.
. Do not spill brake fluid on tho car, it may damage the
pain; if brake fluid does contact the paint, wash it off
immediately with water.
NOTE: The reservoir on the master cylinder must be at
the MAX (upper) level mark at the start of bleeding pro-
cedure, and checked after bleeding each brake caliper.
Add fluid as required.
1. Make sure the brake fluid level in the reservoir is at
the MAX (upper) level line.
MAX (UPPER) I.IVELLINE
CYIINDER
Have someone slowly pump the brake pedal sever-al times, then apply steady pressure.
Loosen the brake bleed screw to allow air to escapefrom the system. Then tighten the bleed screw se-curely.
Repeat the procedure for each wheel in the sequenceshown below, until atr bubbles no longer appear inthe fluid.
Refill the master cylinder reservoir to the MAX(upperl level line,

. Never use an air hoss or dry brush to claan b.ake assemblies.. Use an OsHA-approvod vacuum cleane. to avoid breathing braks dust,. Contaminated brake discs or pads roduce stopping ability.. When rausing tha pads. always rein3tall the brake p8d3 in thoir original positions to prevont loss of braking etticlency.
GAUTION: Do not spill brake fluid on the vehicle; it may damags the paint; it brake fluid do6s contast the paint, wash hoff imm€diately with wator.
NOTE:
. Coat the piston, piston seal, and caliper bore with clean brake fluid.. Replace all rubber pans with new ones whenever disassembled,. Clean all pans in brake fluid and air dry; blow out all passages with compressed air,. Before reassembling, check that all parts are free of dust and other foreign particles.
. Replace parts with new ones whenever specified to do so.. Make sure no din or other foreign matter is 8llowed to contaminate the br8ke fluid.. Always use Genuine Honda DOT3 Brake Fluid. Using non-Honda brake fluid can caus6 corrosion and d€crease the liftof the system.
