How Long Do Car Brakes Last?

When you step on your car’s brake pedal, you expect a quick, smooth stop.

But how long can you trust your brake system to work like that?

If you’re thinking about becoming an auto technician, knowing the basics of brake pad wear is a great place to start.

Keep reading to learn more. In this blog post, we’ll break down what affects brake pad lifespan, when to replace them and what signs to watch for. We’ll also explain how training at Universal Technical Institute (UTI) can help you prepare to turn your curiosity into a career!1

How Do Car Brakes Work?

Car brakes use a simple but powerful system that slows your vehicle by creating friction. Most modern cars have disc brakes on the front wheels and sometimes the rear. Here’s how they work:

  • When you press the brake pedal, brake fluid travels through the brake lines.
  • This pressure pushes a caliper that squeezes the brake pads against a spinning disc (also called a rotor).
  • The friction between the pads and the rotor slows the car down.

Brake pads are designed to wear down over time. That’s why understanding their lifespan matters—especially for those working in automotive service.

How Long Do a Car’s Brake Pads Last?

On average, brake pads last 30,000 to 70,000 miles. But that’s just a rough range.

How you drive, what kind of pads you use and where you drive all make a difference. Some brake pads may need replacing sooner, while others can last longer.

Let’s take a closer look at what affects how long car brakes last.

Type of Brake Pad

Brake pads come in different materials. Each has its own specific pros and cons, as well as a different expected lifespan.

Ceramic brake pads

  • Known for being quiet and clean.
  • Last longer than other types.
  • Ideal for everyday driving but unideal for heavy loads.

Semi-metallic brake pads

  • Made with metals like copper, steel or iron.
  • Offer strong performance and heat resistance.
  • Wear out faster than ceramic pads and can be noisy.

Organic brake pads

  • Made from natural materials like rubber and glass.
  • Softer and quieter.
  • Wear out quicker and aren’t ideal for high-performance vehicles.

Brake Pad Position

Front brake pads usually wear out faster than rear ones. That’s because a vehicle’s front end carries more weight during braking.

Driving Conditions

If you drive in the city with lots of stops and starts, your brakes will wear out faster. But for highway driving? Pads tend to last longer because there’s less stopping and starting.

Style of Driving

Aggressive braking wears pads out faster. Smooth drivers who coast to a stop can make their pads last longer.

4 Common Signs You Need a Brake Pad Replacement

Brake pads won’t last forever. Watch out for these signs that they might need replacing:

Screeching Noise Consistency

Most brake pads have a small metal tab called a wear indicator. When the pad gets too thin, the tab touches the rotor and makes a high-pitched squeal.

Grinding Noise When Applying Brakes

Grinding usually means the brake pad is completely worn down and the metal backing is rubbing against the rotor. This needs fixing right away.

Vibration When Brakes Applied

If your steering wheel shakes or the brake pedal vibrates, your rotors might be uneven. That could be a result of worn pads or warped brake rotors. 

Brake Pad Thickness

If you can see your brake pads, check the wear indicator to see how much pad remains. If it's worn down, it's time to replace them.
