Brake Booster: Notes

WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

The power brake booster:

is a dual-diaphragm, vacuum-assisted power brake booster.
reduces brake pedal effort and pedal travel distance.
is divided into separate vacuum and atmospheric chambers by the diaphragms.
will not operate if vacuum is restricted or if any of the vacuum-related power brake components fail.
