Rust/scratches/wear → Replace the brake
caliper pistons.
• Brake caliper cylinders “2”
Scratches/wear → Replace the brake caliper
assembly.
• Brake caliper body “3”
Cracks/damage → Replace the brake caliper
assembly.

CALIPERS
WARNING
EWA3P6D002
• 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.
