A maximum of 0.0625 inch (1.587 mm) material can be cut from the pad to repair the radius.

Remove any sharp edges from the pad.
c.
Clean and inspect the pistons.
CAUTION
To avoid damage to the pistons, make sure the cleaning solvent
is approved for aluminum. Refer to Federal Specification PD-
680.
(1)
Allow the piston to soak for a minimum of 30 minutes in a tank containing an approved cleaning
solvent for aluminum.
(2)
Use a hot, soapy solution and a nonmetallic brush to remove carbon deposits.
CAUTION
Do not use a metal brush. A metal brush will damage the piston ring
grooves. Do not use glass beads to clean the grooves. Walnut shell
blasting may be used on grooves with a ni-resist insert and on the
dome of the piston.
Use the minimum effective pressure and do not concentrate
the spray in one area for an extended period of time.
Do not use walnut shell blasting on the pin bores or aluminum
grooves. This can damage pin bore surface finish or prevent the
rings from seating correctly in the grooves.
