• Before installation, all internal brake com-
ponents should be cleaned and lubricated
with clean or new brake fluid.
• Never use solvents on internal brake com-
ponents as they will cause the brake caliper
piston dust seals and brake caliper piston
seals to swell and distort.
• Whenever a brake caliper is disassembled,
replace the brake caliper piston dust seals
and brake caliper piston seals.
