What is Hydro Boost?

What is Hydro Boost?

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 do you fix a leaking Hydroboost step?

I use a flathead screwdriver to to pry it over top of the pin, then slide it off. Once that clip is off, you can simultaneously slide the electrical connector and the hydroboost rod off of the brake pedal.

These systems can be mysterious to the untrained technician because part-swapping will not solve some brake issues. The booster is essentially a power steering unit that supplements the driver’s input.
