How do I know I need a Brake Booster Replacement?
When a brake booster fails or begins to fail you will typically notice the following:
- Hard brake pedal
- A hissing or whistling noise, usually when the brake pedal is pressed.
- Increased stopping distance
- Leaking fluid (Hydro-boost)
- Illuminated Warning Light (Electric brake booster)
Types of brake boosters
Vacuum Brake Boosters
Vacuum Brake Boosters are still the most common brake boosted in use. They use engine vacuum to assist you in apply your brakes. The brake booster uses a diaphragm to separate the brake booster chamber. A partial vacuum is created by attaching the brake booster to the engine or vacuum pump, via a one-way check valve. When the driver presses the brake pedal, a valve in the booster opens, allowing atmospheric pressure to enter the booster chamber. At the same time the vacuum source is blocked. The force of air entering at atmospheric pressure, provides a mechanical advantage, allowing for the driver to easily apply the brakes.
Electric Brake Boosters
Electric brake boosts typically come in two varieties. One uses an electric motor to create a vacuum and is effective a more compact version of a brake booster and vacuum pump. The second, uses an electric motor to apply the necessary force to the master cylinder. They uses sensors to determine the drives braking input.
Hydro-boost Brake Booster
Hydro-boost brake boosters use the power steering system to create the additional force to assist the driver with braking. They function similar to the vacuum brake booster, with hydraulic force subsisting the vacuum.
