Air Method

1. Be sure master cylinder attaching nuts are tight.
2. Remove master cylinder filler cap.
3. With brake released, force compressed air into the hydraulic outlet of the master cylinder. Regulate air pressure to a value of approximately 5 psi, to prevent spraying brake fluid from master cylinder. Care must be taken not to allow brake fluid to contact painted surfaces of vehicle, skin or eyes, as damage or personal injury will result.
4. If air passes through the compensating port, which is the smaller of the two holes in the bottom of the master cylinder reservoir, the adjustment is satisfactory.
5. If air does not flow through the compensating port, adjust the pushrod as required, either by means of the adjustment screw (if provided) or by adding shims between the master cylinder and power unit shell until the air flows freely.
6. Reconnect brake lines and bleed system.
