3.3.1
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.

Instrumentation
Kobelt caliper disc brakes may be equipped
with a release indicating proximity switch (part
number
6001-3711
). The connection to the
switch must be made with a 3 pin
–
M8 cable.
