CHAS

• Buffer chamber

The buffer chamber accumulates the brake
fluid that is depressurized while the ABS is
operating.

Buffer chamber (pressurized)

Buffer chamber (depressurized)

Raised piston

• Electronic control unit (ECU)

The ECU (ABS)

controls the ABS and is

installed under the tray bracket. To protect the
ECU (ABS) from water damage, it is protected
by a cover
