Filling the system
ABS uses 2 brake fluid reservoirs, one on the master cylinder and one on the modulator each must maintain a minimum fluid level necessary for the proper functioning of the system.
Although adding fluid does not require relieving the system of pressure, the reservoir caps and surrounding area should be clean of dirt before the cap is removed. Even minor the amount of dirt or foreign matter in the fluid may impair the functioning of the ABS.
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 air-saturated brake fluid that has been used for bleeding or drained from the system. Fill the fluid only to the MAX or UPPER mark on the reservoir. Overfilling the reservoir may cause overflow when testing the system or during operation. After filling, tightly replace the cap on the reservoir.
Pipelines and Supports
The brake system pipes and calipers are bled in the usual way without the use of any special procedures.
Make sure the master cylinder reservoir is full before bleeding begins and check the level frequently. The system must be bled in the correct sequence; always bleed all 4 calipers. Each bleed screw should be tightened to 9 Nm.
Pumping sequence:
- 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 were removed or loosened during repair or if any component was replaced. Bleeding may ONLY be accomplished using the Honda ABS Tester and a special bleed screw T-wrench or equivalent. Do not use any other method or means to bleed high pressure components.
