Introduction
The brake booster is a vital component of your vehicle’s braking system. It amplifies the force you apply to the brake pedal, making it easier to stop the vehicle. If your brake pedal feels unusually stiff or your stopping distance increases, the brake booster might be failing. If you’re considering replacing it, you’re likely wondering: how much is a brake booster at AutoZone? This guide covers pricing, types of brake boosters, installation costs, and buying tips.
What Is a Brake Booster?
The brake booster is typically located between the brake pedal and the master cylinder. It uses vacuum or hydraulic pressure to multiply the force applied when you press the brake pedal. This allows for smoother, more efficient braking with less effort.
Types of Brake Boosters:
- Vacuum Brake Booster: Most common, uses engine vacuum.
- Hydro-Boost Brake Booster: Uses power steering fluid pressure, found in some trucks and diesels.
