19-4 Conventional Brake Components
Brake System Inspection and Test
Inspect the brake system components listed. Repair or replace any parts that are leaking or damaged.










Master Cylinder Look for damage or signs of fluid leakage at:
Reservoir tank, subreservoir or master
cylinder body.
Lines, reservoir tank hose and grommets,
and their joints.
Between master cylinder and booster. Bulging seal at reservoir cap. This is a
sign of fluid contamination.
Brake Hoses Look for damage or signs of fluid leakage at: Line joints and banjo bolt connections.
Hoses and lines, also inspect for twisting or
damage. Bulging, twisted, or bent lines.
Caliper Look for damage or signs of fluid leakage at: Piston seal.
Banjo bolt connections.
Bleed screw. Seized or sticking caliper pins.
ABS or VSA
Modulator-control
Unit Look for damage or signs of fluid leakage at:
Line joints.
Modulator-control unit.
1. Set the parking brake, and start the engine, then turn off the A/C. Allow the engine to warm up to normal operating temperature (radiator fan comes on twice).
2. Attach a 50 mm (2 in.) piece of masking tape along the bottom of the steering wheel, and draw a horizontal reference mark across it.
3. With the transmission in neutral (M/T) or P or N (A/T), press and hold the brake pedal lightly (about the same pressure needed to keep an A/T-equipped vehicle from creeping), then release the parking brake.
4. While still holding the brake pedal, hook the end of the tape measure behind the brake pedal, then pull the tape up to the steering wheel. Note the measurement between the brake pedal and the reference mark on the steering
wheel.
5. Apply steady pressure to the brake pedal for 3 minutes.
6. Watch the tape measure.  If the measurement increases 10 mm (0.39 in.) or less, the master cylinder is OK.
 If the measurement increases more than 10 mm (0.39 in.), replace the master cylinder.

Symptom Troubleshooting
NOTE: Make sure that the caliper pins are installed
correctly.
Upper caliper pin B and lower caliper pin A are different.
If the pins are installed in the wrong location, it will
cause vibration, uneven or rapid pad wear, and
possibly uneven tire wear. For proper caliper pin
location: Except Type S model (see page 19-22), Type S
model (see page 19-23).
1. Drive the vehicle until the brakes drag or until the pedal is high and hard. This can take 20 or more
brake pedal applications during an extended test-
drive.
2. With the engine running, raise the vehicle on a lift, and spin all four wheels by hand.
Go to step 3.
Look for other causes of pad wear, high pedal,
or vehicle vibration.
3. Turn the ignition switch to LOCK (0), press the brake pedal several times to deplete the vacuum in
the brake booster, and then spin the wheels again
to check for brake drag.
Go to step 4.
Replace the brake booster (see page 19-27).
4. Without removing the brake lines, unbolt and separate the master cylinder from the brake
booster, then spin the wheels to check for brake
drag.
Go to step 5.
Check the brake pedal position switch
adjustment, and pedal free play (see page 19-6). 5. Loosen the hydraulic lines at the master cylinder,
then spin the wheels to check for brake drag.
Go to step 6.
Check the master cylinder reservoir for
contamination in the brake fluid. If you find
contamination, flush the entire brake system of all
contaminated fluid. If the brake fluid is OK, replace
themastercylinder(seepage19-24).
6. Loosen the bleed screws at each caliper, then spin the wheels to check for brake drag.
Check the master cylinder reservoir for
contamination in the brake fluid. If you find
contamination, flush the entire brake system of all
contaminated fluid. If the brake fluid is OK,
disassemble and repair the caliper, on the wheel(s)
with brake drag.
Look for and replace any damaged brake lines.
If all brake lines are OK, replace the ABS or VSA
modulator-control unit: ABS (see page 19-90), VSA
(see page 19-171).

1. Remove the center console panel (see page 20-92).
2. Release the parking brake lever fully.
3. Loosen the parking brake adjusting nut (A).
4. Raise the rear of the vehicle, and support it with safety stands in the proper locations (see page
1-11).
5. Remove the rear wheels. 6. Make sure the lever (A) on the rear brake caliper
contacts the stop pin (B).
NOTE: The lever will only contact the stop pin when
the parking brake adjusting nut is loosened.
7. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the rear
wheels.
8. Pull the parking brake lever 1 click.
9. Tighten the parking brake adjusting nut until the parking brakes drag slightly when the rear wheels
are turned.
10. Release the parking brake lever fully, and check that the parking brakes do not drag when the rear
wheels are turned. Readjust if necessary.
11. Make sure the parking brake lever is within the specified number of clicks (8 to 10 clicks).
12. Install the center console panel (see page 20-92).

NOTE:
 Do not reuse the drained 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.
 Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.
 Do not spill brake fluid on the vehicle, it may damage the paint; if brake fluid does contact the paint, wash it
off immediately with water.
 The reservoir connected the master cylinder must be at the MAX (upper) l evel mark at the start of the
bleeding procedure, and checked after bleeding each
wheel location. Add fluid as required.
1. Make sure the brake fluid level in the reservoir (A) is at the MAX (upper) l evel line (B).
2. Have someone slowly pump the brake pedal several times, then apply steady pressure.
3. Start the bleeding at the driver’s side of the front brake system.
NOTE: Bleed the calipers in the sequence shown. 4. Attach a length of clear drain tube (A) to the bleed
screw (B), then loosen the bleed screw to allow air
to escape from the system. Then tighten the bleed
screw securely.
5. Refill the master cylinder reservoir to the MAX (upper) l evel line.
6. Repeat the procedure for each brake circuit until there are no air bubbles in the fluid.

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.
1. Raise the front of the vehicle, and support it with safety stands in the proper locations (see page
1-11).
2. Remove the front wheels. 3. Check the thickness (A) of the inner pad (B) and the
outer pad (C). Do not include the thickness of the
backing plate.
4. If any part of the brake pad thickness is less than the service limit, replace the front brake pads as a
set.
5. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the front
wheels.
