Pressure Bleeding
- Clean master cylinder reservoir cover and surrounding area. Remove reservoir cap. Ensure reservoir is full. Attach Bleeder Adapter (J-35589) to reservoir. Attach bleeding equipment, and pressurize system to 10 psi (.7 kg/cm2 ) for 30 seconds to ensure there are no leaks.
- Slowly increase pressure to 35 psi (2.5 kg/cm2
). Attach a clear hose to hydraulic modulator rearward bleeder valve, and submerge other end of hose in clean container. See Figure. Slowly open rearward bleeder. Allow fluid to flow until no air bubbles are seen from hose. Close valve and repeat procedure for forward bleeder valve.CAUTION: DO NOT allow brake fluid to contact motor pack or electrical connectors. Premature failure of motor pack may result.
- Position shop towel below 4 hydraulic modulator brake pipes. Using flare wrench, slightly open front upper brake pipe fitting at hydraulic modulator. DO NOT allow brake fluid to run down side of motor pack or onto electrical connector. Allow air to escape and tighten fitting. Repeat procedure for remaining 3 brake lines, working from front to rear.
- Ensure master cylinder reservoir is full. Raise and support vehicle. Bleed all 4 wheel calipers. Attach a clear hose to right rear caliper bleeder valve and submerge other end of hose in container of brake fluid.
- Open bleeder valve. Allow fluid to flow until no air bubbles are seen in hose. Tap lightly on cylinder/caliper housing to free trapped air. Close bleeder valve. Repeat process until no air bubbles are seen from hose. Repeat procedure on left rear, right front and left front bleeder valves. Ensure reservoir is full.
