Brake Booster

WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

The vacuum-type power brake booster:

Is a dual diaphragm, vacuum-assisted power brake booster.
Reduces brake pedal force.
Is located on the LH side of the bulkhead in the engine compartment, between the brake pedal and the brake master cylinder.
Is divided into separate chambers by the diaphragms.
Will not operate if the vacuum is restricted or if any of the vacuum-related power brake components fail.
Is installed as an assembly.

If the power assist fails, the brake system continues to operate with increased brake pedal effort.
