Service Overview

The brake servo, also known as the brake booster, is a crucial component that makes braking easier. It uses vacuum pressure from the engine (or a vacuum pump in diesel vehicles) to amplify the force you apply to the brake pedal. Without it, braking would require significantly more effort.

When you press the brake pedal, the servo multiplies that force before it reaches the master cylinder. This allows you to stop a heavy vehicle with minimal effort. A failing brake servo can make your brakes feel hard and require much more force to stop the vehicle, which can be dangerous in emergency situations.

Frequently Asked Questions

The brake servo uses vacuum pressure to multiply the force you apply to the brake pedal. This makes braking much easier and more effective, allowing you to stop quickly in emergency situations without excessive physical effort.

Hard or stiff brake pedal
Increased stopping distance
Hissing noise when brakes applied
Brake pedal feels higher than normal
Engine stalling when braking

While you can technically drive without a working brake servo, it is not recommended. Your brakes will still function, but they will require significantly more force to operate. In an emergency, you may not be able to stop quickly enough to avoid a collision.

A brake servo can last the lifetime of the vehicle in many cases, typically 100,000 to 150,000 miles. However, the internal diaphragm can degrade over time, especially in older vehicles, leading to vacuum leaks and loss of power assistance.
