INSPECTION
3.1
Preparation.
Upon receipt of your WPT product, inspect for and report any evidence of damage.
WARNING:
To avoid damage or personal injury, insure that adequate lifting devices and hand tools are available.
3.2
Check Brake Rotor Disc face run out.
It is strongly recommended that dial indicator checks be made
prior to installation of the caliper brake. Mount the indicator base on the caliper mounting pad and position
the dial indicator tip so that its movement is perpendicular to the face of the brake rotor disc. Position the
indicator tip near the outside diameter of the brake rotor disc, see sketch below. Rotate the disc 360
degrees.
The indicator reading should not exceed 0.015 inches (0.38 mm) T.I.R.
3.3
Check Brake Rotor Disc Concentricity.
Mount the indicator base on the caliper mounting pad and
position the dial indicator tip so that its movement is perpendicular to the brake rotor disc outside diameter.
Rotate the disc 360 degrees.
The indicator reading should not exceed 0.030 inches (0.76 mm) T.I.R.
3.4
Check bearing shaft endplay.
Measure and document the shaft
’s endplay before installing the brake caliper. Using dial indicator as
shown in 3.2 move the shaft back and forth axially against bearings. Endplay must be kept at a minimum.
Record the total movement as shown by the dial indicator and keep for future reference.
