• These instructions show normal floor-mounted installation. This brake may alternately be wall- or ceiling-mounted if necessary.

 

• The brake mounting holes are not equal distances from the brake center. Mounting holes on the anti-drag side are 5-9/16" from the brake pin center. Mounting holes opposite the anti-drag side are 4-15/16" from the brake pin center. Be sure to position the brake over the correct mounting holes.

 

• The brake must be installed with the actuator and hinge pins parallel with the brake base. If necessary, reposition brake by forcing against anti-drag friction.

 

• The brake was correctly adjusted during factory inspection. Since this brake includes spring set parking, the clamp nut A and adjusting nut B must be backed off to install brake on wheel.

 

• A right angle connector assembly should be installed at the parking cylinder port. The inlet fitting may be rotated to any position and tightened.

 

• The C washer below the parking cylinder port is held tight against the spring barrel end by parking spring force.

1. Install brake wheel.

2. Loosen clamp nut A and adjusting nut B enough to slip brake over wheel.

 

3. Tighten adjusting nut B until shoes make firm contact with wheel. Do not tighten further. Final brake adjustment is made after brake is operational.

 

4. With brake base parallel with actuator (per item C above), and with brake wheel and brake pin center lines perpendicular, add shims between brake base and brake platform. Attach base with 5/8" bolts.

After brake system is completely connected, filled with brake fluid, and thoroughly bled, step down hard on brake pedal. Green signal light should go "ON," indicating that the parking brake is released. Release brake pedal. The C washer just below the parking cylinder port (see item F above) should now be away from the spring barrel end because the parking spring is now compressed.

1. Retighten adjusting nut B to clamp shoes tight against the brake wheel.

 

2. Loosen nut B two and one half turns and tighten clamp nut A.

 

3. Both shoes should now be approximately 1/32" from the brake wheel.

 

4. The brake is now properly adjusted. Check service brake and parking brake operation

5. Using F-17 copper gasket seals, screw short thread end of armored hoses into all three actuator ports. Wrench tighten to provide leak-proof seals.

 

6. Use mounting brackets, lock washers and jam nuts provided to attach free end of hose to rigid support. Allow hose slack to permit movement of actuator.

 

7. The brake is now ready to be piped into the hydraulic system.
