Pressure Bleeding

Clean master cylinder reservoir cap and surrounding area. Remove cap. With pressure bleeder tank at least 1/2 full of brake fluid and charged with 20-25 psi (1.41-1.76 kg/cm² ) air pressure, connect tank to master cylinder using proper adapter(s).
On vehicles with rear disc brakes, go to next step. On "D" body with rear drum brakes, a manual override is necessary to permit brake fluid flow to front wheels when pressure bleeding. To enable override, attach Combination Valve Pressure Bleeder Adaptor (J-39177) to combination valve.
Raise and support vehicle. Attach bleeder hose to first bleeder valve to be serviced. See BRAKELINE BLEEDING SEQUENCE table. Place other end of hose in clear container partially filled with clean brake fluid. Submerge end of hose in fluid.
Open release valve on pressure bleeder. Open first bleeder valve to be serviced. When fluid flowing into container is clear and free of bubbles, close bleeder valve securely. Open and close each remaining bleeder valve in turn to finish bleeding system. Disconnect pressure tank from master cylinder. Remove adaptor from master cylinder. Check brake fluid level. Fill as necessary.
