Honda Accord/Prelude 1984-1995 Repair Guide

Filling and Bleeding



The ALB brake system uses 2 brake fluid reservoirs, one on the master cylinder and one on the modulator. Each must be maintained at minimum fluid levels for the system to operate properly.

While relieving the system pressure is not required when adding fluid, the caps of the reservoirs and the surrounding area must be wiped clean of dirt before the cap is removed. The slightest amount of dirt or foreign matter in the fluid may impair the ALB function.

Use only DOT 3 or DOT 4 brake fluid from an unopened container. Do not use other grades or types of brake fluid; never reuse aerated brake fluid which has been bled or removed from the system. Bring the fluid level only to the word MAX or UPPER level on the reservoir. Overfilling the reservoir may cause overflowing during testing or system operation. After filling, install the reservoir cap tightly.


Brake Lines and Calipers

The brake lines and calipers are bled in the usual fashion with no special procedures required. Make certain the master cylinder reservoir is filled before the bleeding is begun and check the level frequently. The system should be bled in the correct sequence; always bleed all 4 calipers. Each bleeder should be tightened to 7 ft. lbs. (9 Nm). The bleeding sequence is:

Accord - Left rear, right front, right rear and left front
Prelude - Right rear, left front, left rear and right front.

Bleeding High-Pressure Components

The modulator, accumulator and power unit must be bled if any of their lines are removed or loosened during repairs or if any component is replaced. Bleeding can ONLY be accomplished with Honda's ALB scan tool and the special bleeder T-wrench or their equivalents. DO NOT attempt to use any other procedures or tools to bleed the high pressure components.
