Pressure plates should not be used if warped in excess of 0.010 inch (0.254
mm) flatness. Excessive warping can result in brake drag especially when
new disk and linings are installed.
Using arbor press, secure lining to pressure plate.
Using arbor press, secure lining to back plates.
Verify linings are tight and movement free with no distortion of parts.
Dry film lubricants such as silicone spray should be applied to anchor bolts
and torque plate bushings to assist sliding motion. Exercise care to verify
that linings do not become contaminated with fluid or lubricant. For best ser-
vice life, cylinders must slide freely in torque plate.
