- Brake Boosters
-
- The power in power
- brakes usually
- comes by way of the
- vacuum that an
- engine creates
- during normal
- operation. When
- the brake pedal is
- activated, a valve
- allows atmospheric
- pressure to build
- in the rear chamber
- of the brake unit.
- The brake piston
- moves against the
- brake master
- cylinder providing
- assistance to the
- driver during a
- stop.
-
- Most cars allow for
- sufficient braking
- power by storing
- needed vacuum, and
- heavier autos use a
- dual brake piston
- assembly for
- greater help in
- braking.
