Bleeding

CAUTION:

• Always use Genuine Honda DOT 3 Brake Fluid. Using

a non-Honda brake fluid can cause corrosion and

decrease 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.

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.

2. Have someone slowly pump the brake pedal several

times, then apply steady pressure.

3. Loosen the brake bleed screw to allow air to escape

from the system. Then tighten the bleed screw

securely.

4. Repeat the procedure for each wheel in the sequence

shown below, until air bubbles no longer appear in

the fluid.

5. Refill the reservoir of master cylinder to the MAX

(upper) level line.

BLEEDING SEQUENCE:

NOTE: Bleed the front calipers first in the bleeding

procedure.

Removal/Installation

CAUTION:

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.

Take care not to damage or deform the brake lines during removal and installation.

To prevent the brake fluid from flowing, plug and cover the hose ends and joints with a shop towel or equivalent

material.

NOTE: Tighten the flare nuts to 15 N-m (1.5 kgf-m, 11 Ibf-ft).

Removal

1. Disconnect the modulator unit 10P and pump motor 2P connectors.

2. Remove the proportioning control valve.

3. Disconnect the brake lines, then remove the modulator unit.

Installation

1. Install the modulator unit, then connect the brake lines.

2. Install the proportioning control valve.

3. Connect the modulator unit 10P and pump motor 2P connectors.

4. Bleed the brake system, starting with the front wheels.

5. Start the engine, and check that the ABS indicator light goes off.

6. Test-drive the vehicle, and check that the ABS indicator light does not come on.
