HYDRAULIC LEAK CHECK

1. Make sure the brake master cylinder reservoir (2K478) is full.

2. Apply the brakes several times and make sure the brake pedal (2455) feel is not spongy. If necessary,

bleed the system. For additional information, refer to BLEEDING - SYSTEM.

3. If the reservoir level is dropping, inspect the brake components, fittings and lines to locate the source of

the leak.

NOTE:

Brake fluid is water soluble and it is possible that all evidence of fluid
leakage has been washed off if the vehicle has been operated in the rain or
snow.

DESCRIPTION & OPERATION

BRAKE SYSTEM

The Blackwood, F150 Pickup and F150 Heritage Pickup are equipped with a vacuum-assisted power braking
system. The braking system is a front-to-rear split hydraulic system. The standard dual brake system is split
front and rear, with the front brakes comprising one circuit and the rear brakes, the other circuit. The front brake
disc is a vented, full-cast type. The caliper is a double-piston type. The rear disc brakes utilize a single piston
brake caliper and brake disc system (if equipped).

The rear drum brakes use a self-adjusting system (F150 Pickup and F150 Heritage Pickup). The optional rear
disc parking brake system is a drum-in-hat parking brake system and is not self-adjusting. The rear brake disc is
a vented, full-cast, drum-in-hat type. The caliper is a single-piston type. Each brake pad is equipped with a
riveted spring clip that secures it to either the brake caliper piston or the brake caliper housing. The Rear Anti-
Lock Brake System (RABS) is standard equipment. A 4-Wheel Anti-Lock Brake System (4WABS) is optional.
On Blackwood, a mechanical parking brake system with a motorized releasing mechanism that activates a shoe-
and-drum system within the rear brake disc. See Fig. 1 and Fig. 2 .
