Manual Bleeding
- Using Tech 1, re-home ABS motors. See ABS MOTOR RE-HOMING PROCEDURE under BLEEDING PRECAUTIONS. Clean master cylinder cap and surrounding area, then remove cap. Fill master cylinder and install cap.
- Bleed hydraulic modulator. Attach clear vinyl bleeder hose to rear bleeder valve on hydraulic modulator. Place other end of hose in clean, transparent container. Partially fill container with clean brake fluid until end of hose is submerged in fluid.
- Open bleeder valve about one half turn. Depress brake pedal and hold. Close bleeder valve and release brake pedal. Wait 5 seconds before repeating procedure. Repeat step 2) to bleed hydraulic modulator front bleeder valve. When fluid flows from both hydraulic modulator bleeder valves, bleed wheels.
- Ensure master cylinder is full. Install clear vinyl bleeder hose onto first wheel bleeder screw to be serviced. See BRAKE LINE BLEEDING SEQUENCE table. Place other end of hose in clean, transparent container. Partially fill container with clean brake fluid so end of hose is submerged in fluid. Open bleeder screw and slowly depress brake pedal and hold.
- Close bleeder screw, and release pedal. Gently pump pedal several times to push air toward wheel cylinders. Repeat procedure until flow of brake fluid is clear and bubble free. Proceed to next bleeder screw. See BRAKE LINE BLEEDING SEQUENCE table. Add brake fluid to master cylinder after bleeding all wheels. Because air may still be trapped in hydraulic modulator, repeat steps 1) to 3) without bleeding wheels.
