The power brake booster and vacuum brake booster are essentially the same part, utilizing vacuum pressure from the engine to assist braking. However, a hydro-boost power brake assist system works differently, using hydraulic pressure from the power steering pump rather than vacuum. Both vacuum and power brake boosters can fail if they lose vacuum pressure or have broken internal parts, while hydro-boost would fail at the same time as a power steering failure. Owners manuals can specify which type of brake booster a particular vehicle uses.

1. Things to Know About Power Brake
Booster & Vacuum Brake Booster

2. The power brake booster is
widely available in cars that
are manufactured after
1968.

3. The power brake booster &
vacuum brake booster are
the same part with each
utilizing vacuum pressure
for functioning.

4. However, a Hydro-Boost
Power Brake Assist
system is completely
different from the power
brake booster.

5. Here are the details about
the various braking system.

6. Functioning
of the
vacuum
brake
booster

7. The vacuum brake booster
gets power from the
engine’s intake manifold
through the vacuum
system.

8. Vacuum gets circulated
Through the brake booster
which applies pressure to
the hydraulic brake lines
when the brake pedal is
placed.

9. This system is used in a
vacuum booster or power
brake booster.

10. However, vacuum brake
booster can fail due to
three reasons-
No vacuum pressure from
the engine
Brake booster not being
able to absorb or create a
vacuum internally
Broken internal parts like
check valve & vacuum hose

11. Hydro-Boost
Power
Assist
service

12. The hydro-boost power
system functions nearly
identical to the vacuum-
based system.

13. However, instead of relying
on vacuum pressure it
utilizes direct hydraulic
pressure.

14. It is powered by the power
steering pump & will fail at
the same time as power
steering.

15. Notwithstanding, this
system uses a series of
back-ups to keep the power
brakes working.

16. Why is
power brake
booster
referred as
vacuum
brake
booster?

17. A brake booster is designed
to provide power-added
assistance to help apply the
brakes.

18. Due to its style of
functioning a brake booster
is known as vacuum brake
booster.

19. It is common for a
hydraulic-powered brake
booster to be referred as
power brake booster.

20. You can refer to your car’s
owner manual to know the
type of brake booster used
in your car.
