- Wrap a cloth around brakelines to absorb escaping brake fluid. Slowly push brake pedal down to force out air. With pedal fully depressed, tighten fittings to prevent air from being sucked into master cylinder when pedal is released. Release pedal.
- Repeat procedure until air is completely purged from master cylinder. When all air has escaped, tighten fittings with pedal down. Release pedal, and depress again. If pedal is not firm, repeat bleeding procedure.
- Attach a rubber drain hose to bleeder fitting on front of master cylinder. Submerge hose in small container half-filled with clean brake fluid. Open bleeder fitting. Loosen the bleeder fitting about 3/4 turn. Slowly push down brake pedal completely.
- Close bleeder fitting, and return pedal to fully released position. Repeat procedure until all air is purged from master cylinder. Repeat procedure at bleeder fitting on rear anti-lock brake electrohydraulic RABS Valve, each wheel cylinder and caliper. See Fig 2
