The fluid seal (piston seal) [A] is placed around the piston to maintain clearance between the pad and the disc. If the seal is in a poor condition, it could lead the pad to wear excessively or the brake to drag, which may cause the temperature of the discs or the brake fluid to increase.
Brake fluid leakage around the pad.
Brakes overheat.
Considerable difference in inner and outer pad wear.
Seal and piston are stuck together.
If the fluid seal is replaced, replace the dust seal [B] as well. Also, replace all seals every other time the pads are changed.

The FI ECU analyzes the motorcycle conditions based
on the signals from the front/rear wheel rotation sensors
and FI sensors (such as the crankshaft sensor and main
throttle sensor), and controls engine power by reducing the
number of ignition and retarding the ignition timing. The
