support with two bolts. When
applying brake, the fluid pressure
in rear caliper piston will
increase. The pressure acts on the
bottom of piston and cylinder and
transfers to lining in order to
push the surface of brake disc.
Caliper will slide on mounting
bolts to the center of vehicle.
with setting up pipe pressure, the
pressure on disc surface is higher
and higher to stop vehicle. When
loosing brake pedal, pipe
pressure will release. The
piston will be back slightly. The
movement of piston will
compensate the wear of lining.
