DISC BRAKE CALIPER CLEANING AND
INSPECTION
Clean the caliper and piston with Mopar brake
cleaner, clean brake fluid, or denatured alcohol. Do
not use any other cleaning agents.
Inspect condition of the caliper piston bore. A fiber
brush can be used to clean the bore if necessary. The
bore should be free of corrosion, pitting, or scoring.
Discoloration of the bore is a normal condition and
not cause for replacement. The bore can be lightly
polished by hand but only with crocus cloth. Do NOT
use any other type of abrasive material for polishing.
Check condition of the caliper piston carefully. The
piston must be free of corrosion, rust, pitting, or scor­
ing, replace the piston if it exhibits any of these con­
ditions. Do NOT use any kind of abrasive material to
restore surface finish of the piston. Abrasives will
damage, or destroy the coating applied to the piston
during manufacture.
CAUTION; Never hone the caliper piston bore, or
use any kind of abrasive material on the piston sur­
face. Honing will result in an oversize bore and
abrasives will damage the piston coating. Either of
these practices will result in piston bind and even­
tual seizure.
