Bleeding Brake System
NOTE:
Use only DOT 4 grade brake fluid.
NOTE:
Start at either rear caliper.
- Raise and support vehicle. Connect bleed unit to brake fluid reservoir. Remove wheels.NOTE: This step must be carried out between bleeding each brake caliper concerned.
- Depress brake pedal a few times to remove any air bubbles in master cylinder.
- Remove protective cap from bleed valve and connect hose from collecting bottle. See Fig 1.
- Open bleed valve and close it again when no air bubbles are visible in emerging fluid. Tighten bleed valve, remove hose from valve and install protective cap again.
- Bleed remaining calipers according to sequence. See BRAKELINE BLEEDING SEQUENCE table.
- Remove bleed unit connector from brake fluid reservoir when bleeding is complete.
- Check for air left in brake system by depressing brake pedal as if braking sharply. With engine off and brake pedal depressed 3-4 times, pedal travel should not exceed 1.57" (40 mm). If pedal travel exceeds 1.57" (40 mm), bleed again and check pedal travel. Repeat until pedal travel is within limit.
- Ensure fluid level is not over MAX mark.
- Install wheels and lower vehicle. Tighten lugs to specification. See TORQUE SPECIFICATIONS .
