Fig. Fig. 1: Bleeding the brakes. Be sure the end of the hose is submerged in clean brake fluid

The Acura anti-lock brake system contains brake fluid under extremely high pressure within the pump, accumulator and modulator assembly. Do not disconnect or loosen any lines, hoses, fittings or components without properly relieving the system pressure. Use only a bleeder T-wrench 07HAA-SG00100 or equivalent to relieve pressure.Improper procedures or failure to discharge the system pressure may result in severe personal injury and/or property damage.

The master cylinder must be full at the start of the bleeding procedure and checked after bleeding each caliper. Add fluid as required. Use only DOT 3 or 4 brake fluid. If a pressure bleeder is not available it will be necessary to have the aid of an assistant to perform this brake bleeding operation.

  1. Have an assistant slowly pump the brake pedal several times and then apply a steady pressure to the brake pedal.
  3. Attach a bleed hose to the bleed screw and place it into a clear container. Loosen the brake bleed screw at the brake caliper and allow the fluid to flow. Close the bleeder.
  5. Repeat this procedure for each brake caliper, until no air bubbles appear in the brake fluid. Use the following brake caliper sequence in order to bleed the brake system properly:

    1986-89 Integra: LF, RR, RF, LR
    1990-93 Integra: RR, LF, LR, RF
    1986-90 Legend: LF, RR, RF, LR
    1991-93 Legend: RR, LF, LR, RF
    Vigor: RR, LF, LR, RF


  1. Check the fluid level in the master cylinder and add, if necessary. Road test the vehicle and check the brake performance. Torque the bleeders to 7 ft. lbs. (9 Nm).
