C ONNECTING TO THE S HOP A IR
1 Connect shop air to the fitting on the brake air can pressure regulator. See
Figure 22 on page 21 if you are installing the brake on a four-wheel drive dyno.
2 Adjust the air pressure by pulling up on the regulator knob and turning
counterclockwise to decrease the pressure to 30 psi (clockwise to increase).
Note: The Spring Applied Brake should be operated at 100 psi, but you will start
with the pressure lower while connecting the air can to aid in lining up the parts.
