1. Uneven pad wear caused
by caliper not sliding
due to improper
clearance or dirt.
2. Uneven Rotor wear
causing a thickness
variation between the
two braking surfaces.
1. Remove caliper and correct
as necessary.
2. Machine Rotor as follows:
a. Machine rotors to obtain
a thickness variation no
greater than .0005" and a
lateral runout no greater
than .004".
b. Check caliper freeness.
With rotor removed, install
caliper and mounting bolts
(pins). Check for ,005"-.012"
clearance at both top and
bottom of caliper. See Figure
5-1. If less than .005" is
found, file with a flat file
until at least .005" is
obtained. DO NOT EXCEED A
MAXIMUM of .012" per end or
.024" total clearance.
Caliper clearance to inboard
reaction pads must be equal
within .004" both at the
top and bottom of the
caliper. This is to ensure
correct alignment of caliper
to knuckle during a brake
application.
c. Remove caliper after
freeness check. Clean pins and
sleeves, replace " 0 " rings,
and apply a light coating of
silicone grease or equivalent
to all contact points and
" 0 " rings.
