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.

NOTE: If both the ABS indicator and the brake system
indicator come on at the same time, check the ABS or
VSA system for DTC’s first: ABS (see page 19-49), VSA
(see page 19-97).
1. Remove the center console (see page 20-92).
2. Disconnect the parking brake switch connector (A) from the parking brake switch (B).
3. Check for continuity between the switch terminal (C) and body ground.
 With the parking brake lever pulled, there s hould
be continuity.
 With the parking brake lever released, there should be no continuity.
NOTE: If the parking brake switch and fluid level
switch are OK, but the brake system indicator does
not function, do the gauge control module self-
diagnostic function (see page 22- 241).
4. Reconnect the parking brake switch connector.
5. Reinstall the center console (see page 20-92). 1. Disconnect the brake fluid level switch connector.
2. Check for continuity between the terminals (1) and
(2) with the float in the down position and in the up
position.
NOTE: Remove the brake fluid completely from the reservoir. With the float down, there should be
continuity.
 Fill the reservoir with brake fluid to the MAX (upper) level (A). With the float up, there should
be no continuity.
 If both the ABS indicator and the brake system indicator come on at the same time, check the
ABS or VSA system for DTC’s first: ABS
(see page 19-49), VSA (see page 19-97).
 If the parking brake switch and fluid level switch are OK, but brake system indicator does not
function, do the gauge control module self-
diagnostic function (see page 22-241).
3. Reconnect the brake fluid l evel switch connector.

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.

3. Remove the front wheels.
4. Remove the flange bolt (A) while holding the caliper pin (B) with a wrench. Be careful not to
damage the pin boot, and pivot the caliper (C) up
out of the way. Check the hose and pin boots for
damage and deterioration.
5. Remove the pad shims (A) and the brake pads (B). 6. Remove the pad retainers (A).
7. Clean the caliper bracket (B) thoroughly; remove
any rust, and check for grooves and cracks. Verify
that the caliper pins (C) move in and out smoothly.
Clean and lube if needed.
8. Inspect the brake disc for runout, thickness, parallelism (see page 19-19) and check for damage
and cracks.
9. Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the retainer mating surface of the
caliper bracket (indicated by the arrows).

11. Install the brake caliper piston compressor tool (A)
on the caliper body (B).
12. Press in the piston with the brake caliper piston compressor tool so the caliper will fit over the
brake pads. Make sure the piston boot is in position
to prevent damaging it when pivoting the caliper
down.
NOTE: Be careful when pressing in the piston;
brake fluid might overflow from the master
cylinder’s reservoir. If brake fluid gets on any
painted surface, wash it off immediately with water.
13. Remove the brake caliper piston compressor tool. 14. Apply a thin coat of M-77 assembly paste (P/N
08798-9010) to the pad side of the shims (A), the
back of the brake pads (B), and the other areas
indicated by the arrows. Wipe excess assembly
paste off the pad shims and the brake pads friction
material. Keep grease and assembly paste off the
brake disc and the brake pads. Contaminated brake
disc or brake pads reduce stopping ability.
15. Install the brake pads and the pad shims correctly. Install the brake pad with the wear indicator (C) on
the upper inside. If you are reusing the brake pads,
always reinstall the brake pads in their original
positions to prevent a momentary loss of braking
efficiency.
