The air gap between the tip of the sensor and the pulser is critical to the proper operation of the system. The gap is established by the correct installation of the wheel speed sensor; the gap may be measured for reference but is not adjustable.
Use a non-metallic feeler gauge to measure the gap. Rotate the hub or axle slowly by hand, taking measurements at several locations. Specifications are as follows:
FILLING THE SYSTEM
The ABS 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 ABS function.
Use only DOT 3 or DOT 4 brake fluid from an unopened can. 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 (master cylinder) or UPPER (modulator) on the reservoir. Overfilling the reservoir may cause overflowing during testing or system operation. After filling, install the reservoir cap tightly.
BLEEDING THE SYSTEM
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.Bleeding High-Pressure Components
The modulator, accumulator and power unit must be bled if any of the lines are removed or loosened during repairs or if any component is replaced. Bleeding can only be accomplished with the ABS checker (07HAJ-SG00100) and the special bleeder T-wrench (07HAA-SG00100) or their equivalents. Do not attempt to use any other procedures or tools to bleed the high pressure components.
- Park the vehicle on level ground. Block the wheels. Place the shift selector in P (automatic) or neutral (manual). Make certain the ignition is OFF .
- Disconnect the 6-pin inspection connector and connect to the checker. The pink connector is located under the drivers seat on the Integra, and under the passengers seat on the Legend and Vigor. Connect the ABS checker.
- Make certain the brake fluid reservoir on the modulator is filled to the upper mark. Do not reuse any fluid previously bled from the system.
- Using the bleeder tool, bleed high pressure fluid from the port on the power unit. Close the bleeder port.
- Start the engine and release the parking brake.
- Select Modes 2, 3, 4 and 5 on the ABS checker, depress and hold the brake pedal firmly and press the START TEST button on the checker. There should be at least two strong kickbacks through the brake pedal.
- If there is poor or no kickback in the pedal, turn the ignition switch OFF . Repeat the bleeding at the power unit and repeat the mode tests. (Steps 5 and 6, above)
- Once proper strong pedal kickback is achieved, turn the ignition OFF . Check and adjust the fluid level in the modulator reservoir as necessary. Secure the cap on the reservoir.
- Use the ABS checker to test the system in all modes.
