AUTOMATIC BRAKE-LOCK ADJUSTER SYSTEM
The automatic brake-lock adjuster system is equipped on the brake-lock. If the brake pad worn, the adjust-
bolt/nut adjust the position of caliper piston so as to keep the certain clearance between brake pad and
brake disk.
OPERATION (Normal condition➔
➔➔
➔Braking)
The hydraulic pressure by brake lever operation acts on the adjust-nut/caliper piston. The adjust-bolt
threads and adjust-nut threads have a clearance. The piston stroke when braking is shorter than clearance,
thus, the braking operation will finish without automatic brake-lock adjuster system operation.
