1. Joint seals
To prevent injury, never place fingers or hands inside
the caliper opening when removing the pistons. Always
wear eye, hand and face protection when using
compressed air. Eye, face and skin damage will result
from direct contact with compressed air or brake fluid.
Ensure that the caliper bores do not become scratched
during piston removal and assembly. Ensure that the
pistons remain square to their bores during fitment
otherwise damage to the caliper could result.
A dangerous riding condition leading to an accident
could result if this warning is ignored.
Brakes
3. Cover the caliper half with a clean, heavy cloth and,
using compressed air, remove the pistons, one at a
time.
Ensure the seal grooves in the caliper are not damaged
during the removal of the seals. Damage to the seal
grooves may allow brake fluid to leak past the seals
resulting in a dangerous riding condition leading to loss
of motorcycle control and an accident.
4. Remove the old piston seals and the dust seals then
thoroughly clean and dry the caliper bores. Discard
the old seals.
Inspection
1. Check the pistons and caliper bores for corrosion,
scoring and damage. Renew as necessary.
Always renew caliper seals and pistons after removal
from the caliper. An effective hydraulic seal can only be
made if new components are used. A dangerous riding
condition leading to an accident could result if this
warning is ignored.
2. Inspect the brake pads for damage and wear beyond
the service limit. Renew as necessary.
Assembly
Never use mineral based grease in any part of the
braking system or in any area where contact with the
braking system is possible. Mineral based grease will
damage the hydraulic seals in the calipers and master
cylinders. A dangerous riding condition leading to loss
of motorcycle control and an accident could result from
use of mineral grease.
Note:
• The piston seals are slightly thicker than the
dust seals.
