16. Pivot the caliper down into position. Install theflange bolt (A), and tighten it to the specified torque
while holding the caliper pin (B), with a wrench
being careful not to damage the pin boot. 17. Clean the mating surfaces between the brake disc
and the inside of the wheel, then install the front
wheels.
18. Press the brake pedal several times to make sure the brakes work.
NOTE: Engagement may require a greater pedal
stroke immediately after the brake pads have been
replaced as a set. Several applications of the brake
pedal will restore the normal pedal stroke.
19. Add brake fluid as needed.
20. After installation, check for leaks at hose and line joints or connections, and retighten if necessary.
Test-drive the vehicle, then recheck for leaks
(see page 19-37).

2. Remove the front wheels.
3. Remove the brake pads: Except Type S model (see page 19-13), Type S model (see page 19-16).
4. Inspect the brake disc to wheel surface for damage and cracks. Clean the brake disc thoroughly, and
remove all rust.
5. Install suitable flat washers (A) and wheel nuts (B), and tighten the wheel nuts to the specified torque
to hold the brake disc securely against the hub.
6. Set up the dial gauge against the brake disc as shown, and measure the runout at 10 mm (0.39 in.)
from the outer edge of the brake disc. 7. If the brake disc is beyond the service limit, refinish
the brake disc with a Honda-approved
commercially available on-car brake lathe.
NOTE: If the brake disc is beyond the service limit for refinishing, replace it (see page 19-21).
 If the brake disc is replaced with a new one, check the new disc for runout. If the new disc is
out of specification, refinish the disc.
8. Install the brake pads: Except Type S model (see page 19-13), Type S model (see page 19-16).
9. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the front

2. Remove the front wheel.
3. Remove the brake hose mounting bolt (A) from the damper.
4. Remove the brake caliper bracket mounting bolts (B), then remove the caliper assembly (C) from the
knuckle. To prevent damage to the caliper
assembly or brake hose, use a short piece of wire
to hang the caliper assembly from the
undercarriage. Do not twist the brake hose
excessively. 5. Remove the brake disc flathead screws (A).
6. Remove the brake disc (B) from the front hub.
NOTE: If the brake disc is stuck to the front hub,
thread two 8 x 1.25 mm bolts (C) into the brake disc
to push it away from the front hub. Turn each bolt
90 degrees at a time to prevent the brake disc from
binding.
7. Install the brake disc in the reverse order of removal.

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.
Remove, disassemble, inspect, reassemble, and install the caliper, and note these items:
NOTE: Make sure that the caliper pins are installed correctly. Upper caliper pin B and lower caliper pin A are different.
If these caliper pins are installed in the wrong location, it will cause vibration, uneven or rapid brake pad wear, and
possibly uneven tire wear.  Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid gets on the paint, wash it off immediately with water.
 To prevent dripping brake fluid, cover disc onnected hose joints with rags or shop towels.
 Clean all parts in brake fluid and air dry; blow out all passages with compressed air.
 Before reassembling, check that all parts are free of dirt and other foreign particles.
 Replace parts with new ones as specified in the illustration.
 Make sure no dirt or other foreign matter gets in the brake fluid.
 Make sure no grease or oil gets on the brake discs or pads.
 When reusing brake pads, always reinstall them in their original positions to prevent loss of braking efficiency.
 Do not reuse drained brake 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.
 Coat the piston, the piston seal groove, and the caliper bore with clean brake fluid.
 Use recommended greases in the front caliper set.
 After installing the caliper, check the brake hose and line for leaks, interference, and twisting.
Install inner brake pad with
its wear indicator upward.

1. Remove the master cylinder (see page 19-24).
2. Inspect and note these items:
 Before reassembling, check that all parts are freeof dirt and other foreign particles.
 Do not try to disassemble the master cylinder assembly. Replace the master cylinder assembly
with a new part if necessary.
 Do not allow dirt or foreign matter to contaminate the brake fluid. 3. If the reservoir tank hose was disconnected, install
the reservoir tank (A) and the reservoir tank hose
(B) to the subreservoir (C).
NOTE: Align the ‘‘ ’’ marks (D) on the reservoir tank and subreservoir with the paint marks (E) on the
hose.
 Position the direction of the clamp (F).
4. Install the master cylinder (see page 19-24).

Functional Test

19-26 Conventional Brake Components
Brake Booster Test
A
1. With the ignition switch in LOCK (0), press the
brake pedal several times to deplete the vacuum
reservoir, then press the brake pedal hard, and hold
it for 15 seconds. If the brake pedal sinks, either the
master cylinder is bypassing internally, or the
brake system is leaking. Inspect the brake hoses
and lines (see page 19-37).
2. Start the engine with the brake pedal pressed. If the brake pedal sinks slightly, the vacuum booster is
operating normally. If the brake pedal height does
not vary, do the brake system test (see page 19-4).
1. Press the brake pedal with the engine running, then stop the engine. The brake pedal height should not
vary while pressed for 30 seconds.
 If the pedal height rises, go to step 6.
 If it does not rise, go to step 2.
2. Start the engine and let it idle for 30 seconds. Turn the ignition switch to LOCK (0), and wait
30 seconds. Press the brake pedal s everal times
using normal pressure. When the pedal is first
pressed, it should be low. On consecutive
applications, the pedal height should gradually rise.
Does the pedal rise on each consecutive
application?
 If it rises the booster is OK.
 If it does not rise, go to step 3. 3. Disconnect the brake booster vacuum hose (A) at
the booster. The check valve is built into the hose.
NOTE: If the check valve is faulty, replace the brake
booster vacuum hose/check valve as an assembly.
4. Start the engine, and let it idle. There should be vacuum available.
 If no vacuum is available, the check valve is not working properly. Replace the brake booster
vacuum hose and check valve, and retest.
 Ifthereisvacuum,gotostep5.
5. With the ignition switch in LOCK (0), reconnect the vacuum hose to the brake booster.
6. Start the engine, and then pinch the brake booster vacuum hose between the check valve and the
booster.
7. Turn the ignition switch to LOCK (0), and wait 30 seconds. Press the brake pedal several times
using normal pressure. When the pedal is first
pressed, it should be low. On consecutive
applications, the pedal height should gradually rise.
 If the pedal position does not vary inspect the seal between the master cylinder and booster. If
the seal is OK, replace the brake booster.
 If the pedal position varies, replace the brake booster vacuum hose/check valve as an
assembly.
