Warning
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.
Note:
Only the top two pistons (near the brake
•
hose) are Nymfron coated;
• The Nymfron coated pistons appear to have
a matt finish compared to the Nickel plated
pistons;
• Note the position of the Nymfron coated
pistons.
1. Cover the caliper opening with a clean heavy cloth
and using either compressed air or by reconnecting
the master cylinder and pumping the brake lever,
remove the pistons one at a time.

Ensure the seal grooves in the caliper bores 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.

scoring and damage. Renew as necessary.
A Wa
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.
