Introduction
Your vehicle’s brake booster is a vital component of the braking system, helping to amplify the force you apply to the brake pedal so that you can stop your car with ease. If your brake pedal feels hard or you notice reduced braking power, a failing brake booster might be the culprit. If you’re wondering how much is a brake booster at AutoZone, this guide covers everything you need to know—including cost ranges, types of brake boosters, symptoms of failure, and what to consider when buying a replacement.
What Is a Brake Booster?
A brake booster is a diaphragm-like device located between the brake pedal and the master cylinder. It uses engine vacuum (or hydraulic pressure in hydro-boost systems) to multiply the force you apply with your foot, making braking easier and more effective.
Types of Brake Boosters:
- Vacuum Brake Boosters: Most common; use engine vacuum.
- Hydro-Boost Systems: Found in heavy-duty trucks and diesel vehicles; use power steering pressure.
Symptoms of a Bad Brake Booster
- Hard brake pedal
- Increased stopping distance
- Hissing noise when pressing the brake
- Engine stalling when brakes are applied
- Illuminated brake warning light
If you notice any of these symptoms, it may be time to replace the brake booster.
