Simply flushing the hydro-boost system may cure the problem. In terms of functionality, a brake booster does the same for a braking mechanism what power steering does for steering.

It uses a vacuum to balance the high fluid pressure in the braking system of a vehicle, facilitating effective braking. They are separated by a diaphragm. This is one of the most important functions of the vehicle as it is a safety provision that protects the driver and passengers.

The Brake Booster: These systems can be mysterious to the untrained technician because part-swapping will not solve some brake issues.

If the booster is working properly, the pedal will drop toward the floor and then push back upward slightly.

How Power Brakes Work

This ensures that there is no vacuum in the booster. Related " ". The Non-Vacuum Booster Hydro-boost brake boosters use the pressure of the power steering pump to power the brake booster. The major function of brake boosters is to increase the power applied to on the pedal. Start the engine and allow it to idle while observing the vacuum gauge.

Vacuum Booster Diagnostics

Hydro-boost operation and accumulator performance must also be tested. At the end of the hour, repeatedly apply the brake pedal with medium force. With the ignition off, pump the brake pedal to deplete the booster reserve.

Welcome, Login to your account. Brake boosters are available with two different diaphragms — single for smaller vehicles and tandem for bigger cars and trucks.
