ALIPER BRAKES
2.3.1 Mechanical
Perform the following steps to properly install a caliper brake:
1. Lower the brake onto the brake pedestal and center over the mounting holes.
2. Using feeler gauges to ensure that the brake air gap is equal on both sides of the disc.
Ensure the caliper is centered. The balancing link will be subjected to
excessive stresses that will damage it.
3. Position the brake so that the outer radius of the brake shoe is in full contact with the
Disc. Do not move the brake too close as enough radial distance must be provided to
allow for disc expansion without causing interference between the outer circumference
of the disc and the inner caliper frame.
4. Manually apply the brake onto the disc. The brake shoes will naturally align with the disc.
5. Probe under the brake base with feeler gauges to determine the shimming requirement.
6. Manually release the brake again and lift the brake up approximately two inches.
7. Insert the shims determined from step 6. Use ANSI shims that straddle the mounting
bolts.
8. Insert the mounting bolts from underneath the pedestal using appropriate flat washers.
The nut must be on top of the brake foot. The mounting bolts must be of SAE grade 5 or
better. It is recommended to use a thread locking product such as Loctite® to ensure a
vibration resistant and secure joint.
9. Lower the brake down and tighten the mounting bolts to the recommended preload.
2.3.2 Piping
The piping to the brakes must be adequately sized to ensure rapid response times in all weather
conditions. The piping must be selected to safely withstand the pressures required to operate
the brakes. Secure the piping against vibration with pipe clamps per the schedule in the table
below.

All piping must be cleaned prior to connection to the actuators. Welded carbon steel piping
must be pickled to remove the scale produced by welding.
The connections to the brake actuators must be made by hoses of suitable rating to
accommodate the movement of the brake levers.
