Rear Brake Caliper – Assembly
Never use mineral-based grease (such as lithium or copper based grease) in any area
where contact with the braking system hydraulic seals and dust seals is possible.
Mineral-based grease will damage the hydraulic seals and dust seals in the calipers
and master cylinders.
Damage caused by contact with mineral-based grease may reduce braking efficiency
resulting in loss of motorcycle control and an accident.
Before installation, all internal brake components should be cleaned and lubricated
with clean new DOT 4 brake fluid.
Never use solvents, petrol (gasoline), engine oil, or any other petroleum distillate on
internal brake components as this will cause deterioration of the hydraulic seals in the
calipers and master cylinders.
A dangerous riding condition leading to loss of motorcycle control and an accident
could result if this warning is ignored.
If all components are serviceable, obtain a piston seal kit and reassemble the caliper as
follows:
1. Make sure all components are clean, then fit the new seals to their grooves in the
caliper bores.
2. Lubricate the fluid seals, caliper bore and the outside of the pistons with clean DOT 4
brake fluid.
3. Ease the pistons squarely back into the bores, taking care not to displace the seals.
