What is a hydro booster?
Technically known as a hydraulically boosted brake system, instead of vacuum, a Hydroboost uses hydraulic fluid supplied by the same power-steering pump that supplies fluid to the steering-gear or steering-rack to boost brake pedal force.
How does Hydro boost braking work?
Hydro-boost systems use hydraulic pressure from the power steering pump to amplify brake pedal effort. Pressurized fluid also flows through the hydro-boost to the steering gear to provide power steering. Expect to see about 450 to 600 psi during normal brake application or when the wheels are turned.
How do you test a booster?
Check vacuum at idle with a vacuum gauge. To test booster function once the reserve is depleted, hold moderate pressure on the brake pedal and start the engine. If the booster is working properly, the pedal will drop slightly.
What fluid Do Hydro boosters use?
power steering fluid
The hydro-boost requires a constant source of pressurized power steering fluid for proper operation.
