Kawasaki Ninja Service Manual: Rear Caliper Holder Shaft Wear

Kawasaki Ninja Service Manual / Brakes / Calipers / Rear Caliper Holder Shaft Wear

The caliper body must slide smoothly on the caliper holder shafts [A]. If the body does not slide smoothly, one pad will wear more than the other, pad wear will increase, and constant drag on the disc will raise brake and brake fluid temperature.

If the rubber friction boot is damaged, replace the rubber friction boot. To replace the friction boot, remove the pads and the caliper bracket.

If the caliper holder shaft is damage, replace the caliper bracket.
