both the non-antilock braking systems and antilock
braking systems. That means the left front and right
rear brakes are on one hydraulic circuit and the right
front and left rear are on the other.

For information on the brake lamp switch, (Refer

to 8 - ELECTRICAL/LAMPS/LIGHTING - EXTERI-
OR/BRAKE LAMP SWITCH - DESCRIPTION)

Optional antilock brakes are available with or

described in detail in ANTILOCK BRAKE SYSTEM.

DESCRIPTION - BASE BRAKES (EXPORT)

Four-Wheel Disc Antilock Brakes are standard on

all models.

OPERATION - BASE BRAKES

When a vehicle needs to be stopped, the driver

applies the brake pedal. The brake pedal pushes the
input rod of the power brake booster into the booster.
The booster uses vacuum to ease pedal effort as force
is transferred through the booster to the master cyl-
inder. The booster’s output rod pushes in the master
cylinder’s primary and secondary pistons applying
hydraulic pressure through the chassis brake tubes
to the brakes at each tire and wheel assembly.

The

parking

brakes

are

foot-operated.

When

applied, the parking brake lever pulls on cables that
actuate brake shoes at each rear wheel. These shoes
come in contact with a hub mounted drum (drum for
disc/drum brakes or drum-in-hat for disc/disc brakes)
and hold it in place.
