BRAKE PIPES AND HOSES
The brake pipes and hoses connect the master cylinder
to the wheel brakes via the hydraulic control unit. The
pipes are arranged to provide a front and rear split
braking system. The brakes on the front axle are
operated by the primary system; the brakes on the rear
axle are operated by the secondary system.

Lesson 2 – ChassisParking Brake 

GENERAL
The parking brake is an electrically actuated system that
operates drum brakes integrated into the rear brake discs.
The parking brake system consists of:
•A parking brake switch.
•Left and right drum brakes.
•Left and right brake cables.
•An emergency release cable.
•A clutch pedal position sensor (manual transmission
models only).
•Two parking brake indicators.
•A parking brake module.
The parking brake is operated by the parking brake
module, which adjusts the tension of the brake cables
to...

Lesson 2 – ChassisParking Brake 

Each drum brake consists of a pair of brake shoes
installed on a backplate attached to the rear hub carrier.
The brake shoes operate on the drum integrated into the
rear brake disc. The orientation of the brake shoes differ
by 180° between the LH and RH brakes.
When the parking brake module tensions the brake
cables, the movement is transmitted to an operating
lever on one of the brake shoes. The operating lever
pivots against a cross strut, which forces the brake shoes
apart and into contact with the...

Lesson 2 – ChassisParking Brake 

The brake cables consist of Bowden cables installed
between the parking brake module and the drum brakes.
Nuts, on the ends of the outer cables, secure the brake
cables to the parking brake module and the backplate
of the related drum brake. In each drum brake, the inner
cable is located in the guide spring and connected to the
brake shoe operating lever by a nipple on the end of the
cable. In the parking brake module, the two inner cables
are joined together via the force sensor and the spline
shaft....
