Parking Brake - E-150 - E-450

WARNING: This page is about a different car, the 2003 Ford RV Cutaway, 2003 Ford Econoline, 2003 Ford E550 Super Duty, 2003 Ford E450 Super Duty, and 2003 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

On E-150, E-250 and E-350, the parking brake is a drum-in-hat type system mounted in the hub of the disc brake. On the E-450 and E-550, the parking brake is mounted to the transmission extension housing. All systems are controlled by a foot-operated parking brake control mounted on the steering column support bracket.

On E-150, E-250 with multiplier, and E-350, the parking brake cable is self-adjusting. On E-250 with tension limiter, E-450 and E-550, the parking brake cable is adjustable.

The parking brake system is actuated when the parking brake control is depressed. The parking brake control applies tension to the front parking brake cable and conduit, the parking brake intermediate cable, and the parking brake cable equalizer. The parking brake cable equalizer is coupled to the RH parking brake rear cable and conduit, and the LH parking brake rear cable and conduit. The respective rear brake assemblies are then applied.

If the parking brake control is not fully released, the parking brake signal switch will illuminate the brake warning light.

The parking brake signal switch is mounted on the parking brake control.
