  • Bleed screw.
Seized or sticking caliper pins.
VSA Modulator-control Unit Look for damage or signs of fluid leakage at:
  • Line joints.
  • Modulator-control unit.
 

Brake System Test

Brake pedal sinks/fades when braking

  1. Set the parking brake, and start the engine, then turn off the A/C switch. 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 M/T in the neutral position, A/T in the P or N position, 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 (3/8 in.) or less, the master cylinder is OK.
    • If the measurement increases more than 10 mm (3/8 in.), replace the master cylinder.

Symptom Troubleshooting

Rapid brake pad wear, vehicle vibration (after a long drive), or high, hard brake pedal

NOTE: Make sure that the caliper pins are installed correctly.

The 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 brake pad wear, and possibly uneven tire wear. For proper caliper pin location (see FRONT BRAKE CALIPER OVERHAUL ).

  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.

    Is there brake drag at any of the wheels?

    YES - Go to step 3.

    NO - Look for other causes of the pad wear, high pedal, or vehicle vibration.

  3. Turn the engine off, 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.

    Is there brake drag at any of the wheels?

    YES - Go to step 4.

    NO - Replace the brake booster (see BRAKE BOOSTER REPLACEMENT ).

  4. Without removing the brake lines, unbolt and separate the master cylinder from the booster, then spin the wheels to check for brake drag.

    Is there brake drag at any of the wheels?

    YES - Go to step 5.

    NO - Check the brake pedal position switch adjustment and pedal free play (see PEDAL FREE PLAY ).

  5. Loosen the hydraulic lines at the master cylinder, then spin the wheels to check for brake drag.

    Is there brake drag at any of the wheels?

    YES - Go to step 6.

    NO - 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 the master cylinder (see MASTER CYLINDER REPLACEMENT ).

  6. Loosen the bleed screws at each caliper, then spin the wheels to check for brake drag.

    Is there brake drag at any of the wheels?

    YES - 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.

    NO - Look for and replace any damaged brake lines. If all brake lines are OK, replace the VSA modulator-control unit (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION ).

Brake Pedal and Brake Pedal Position Switch Adjustment

Pedal Height

  1. Turn the brake pedal position switch (A) counterclockwise, and pull it back until it is no longer touching the brake pedal.

    Fig. 2: Identifying Pedal Height
    Courtesy of AMERICAN HONDA MOTOR CO., INC.

  2. Pull back the carpet and find the cutout in the insulator. Lift up the insulator cutout and measure the pedal height (B) at the center of the pedal pad (C) to the floor.

    Standard pedal height (with carpet removed):

    M/T model: 144 mm (5 11/16 in.)

    A/T model: 148 mm (5 13/16 in.)

  3. Loosen the pushrod locknut (A), and screw the pushrod (B) in or out with pliers until the standard pedal height from the floor is reached. After adjustment, tighten the locknut firmly. Do not adjust the pedal height with the pushrod pressed.

    Fig. 3: Loosening Pushrod Locknut w/Torque Specification
    Courtesy of AMERICAN HONDA MOTOR CO., INC.

  4. Lift up on the brake pedal by hand. Push in the brake pedal position switch until its plunger is fully pressed (threaded end (A) touching the pad (B) on the pedal arm). Then, turn the switch 45° clockwise to lock it. The gap between the brake pedal position switch and the pad is automatically adjusted to 0.7 mm (0.028 in.) by locking the switch. Make sure the brake lights go off when the pedal is released.

    Courtesy of AMERICAN HONDA MOTOR CO., INC.

  5. Check the brake pedal free play.

Pedal Free Play

  1. With the engine off, inspect the play (A) on the brake pedal pad (B) by pushing the brake pedal by hand. If the brake pedal free play is out of specification, adjust the brake pedal position switch (C). If the brake pedal free play is insufficient, it may result in brake drag.

    Free play: 1-5 mm (1/16-3/16 in.)

Parking Brake Inspection and Adjustment

Check

  1. Pull the parking brake lever (A) with 196 N (20 kgf, 44 lbf) of force to fully apply the parking brake. The parking brake lever should be locked within the specified number of clicks (B).

    Lever locked clicks: 6 to 9

    Pulled up with 196 N.m (20 kgf.m, 44 lbf.ft)

  8. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the rear wheels.
  9. Tighten the 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 brakes are fully applied when the parking brake lever is pulled all the way.
  12. Install the center console (see CENTER CONSOLE REMOVAL/INSTALLATION ).

Brake System Bleeding

NOTE:
  • Do not reuse the drained fluid. Use only clean Acura DOT 3 Brake Fluid from an unopened container. Using a non-Acura brake fluid can cause corrosion and shorten the life of the system.
  • Do not mix different brands of brake fluid; they may not be compatible.
  • 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 to the master cylinder must be at the MAX (upper) level mark at the start of the bleeding procedure and checked after bleeding each wheel. Add fluid as required.

  1. Make sure the brake fluid level in the reservoir is at the MAX (upper) level line (A).

    Fig. 10: Identifying Brake Fluid Level In Reservoir

  2. Attach a length of clear drain tube to the bleed screw.
  3. Have someone slowly pump the brake pedal several times, then apply steady pressure.
  4. Starting at the left-front, loosen the brake bleed screw to allow air to escape from the system. Then tighten the bleed screw securely.
  5. Repeat the procedure for each wheel in the sequence shown following until air bubbles no longer appear in the fluid.
