How do I know what kind of brakes I have?
Knowing the type of brakes on your vehicle is important for proper maintenance, repairs, and safety. There are several common brake types, and the specific system can vary depending on the make, model, and year of your car. In this article, we'll explore how to identify the brake system on your vehicle.
Identifying Brake Types
The most common brake types found on modern vehicles are disc brakes and drum brakes. Disc brakes use a rotor (disc) and caliper with brake pads that squeeze the rotor to slow the wheel. Drum brakes use an internal expanding shoe that presses against the inside of a drum to create friction and slow the wheel.
- To check if you have disc brakes, look behind the wheel and you should see a round, flat metal disc (the rotor) and a caliper that straddles the rotor.
- For drum brakes, you won't see a rotor - instead, you'll see a round, enclosed drum that the brake shoes press against.
Some vehicles may also have a combination of disc and drum brakes, with disc brakes on the front wheels and drum brakes on the rear wheels.
Identifying Brake Components
In addition to the brake type, it's also helpful to identify the specific brake components on your vehicle. This can include:
- Brake pads: The friction material that presses against the rotor on disc brakes.
- Brake shoes: The friction material that presses against the drum on drum brakes.
- Brake calipers: The component that houses the brake pads and squeezes the rotor on disc brakes.
- Brake drums: The enclosed component that the brake shoes press against on drum brakes.
- Brake rotors: The flat, circular discs that the brake pads grip on disc brake systems.
Knowing the specific components of your brake system can help you identify any issues and ensure proper maintenance.
Checking Your Owner's Manual
If you're still unsure about the type of brakes on your vehicle, consult your owner's manual. The manual should provide details on the brake system, including the type of brakes and any specific maintenance requirements.
Properly identifying your vehicle's brake system is an important step in maintaining its safety and performance. By understanding the type of brakes and their components, you can better care for your car and ensure it stops reliably when you need it to.
How do I tell what type of brakes I have?
Not sure which type(s) of brakes your car has? Check behind your front and rear wheels. If you're having difficulty seeing the brakes with your wheels in front, safely remove the wheel so that you can get a better look at your braking system. Look out for a caliper assembly, disc or drum.
How do I tell if it's my brakes or rotors?
You may need new brakes and rotors if you hear squealing or grinding noises, feel vibrations in the pedal or steering wheel, or notice your vehicle pulling to one side when braking. Other signs include longer stopping distances, a spongy or pulsating brake pedal, or a visible warning light on your dashboard. If you experience any of these symptoms, have a professional inspect them immediately, as the rotors may be warped, grooved, or have other damage that compromises braking.

- Unusual noises: Squealing, squeaking, or grinding sounds when you brake are classic indicators of worn pads or damaged rotors.
- Vibrations or pulsation: A vibrating or pulsating feeling in the brake pedal or steering wheel while braking is often a sign of warped rotors.
- Pulls to one side: If your car consistently pulls to one side when you brake, it could indicate a problem with one side's brakes or rotors.
- Increased stopping distance: If it takes longer to stop your car than it used to, your braking system may not be as effective as it should be.
- Spongy or low brake pedal: If the brake pedal feels soft, sinks to the floor, or feels excessively spongy, it could mean low brake fluid or worn-out components.
- Dashboard warning light: A red brake warning light or the ABS (Anti-lock Braking System) light on your dashboard indicates a problem that needs immediate attention.
- Visible signs of damage: Visually inspecting your rotors can reveal damage such as deep grooves, scoring, or a bluish discoloration from overheating.
Why you should replace them together
- New brake pads on a damaged rotor will not be able to make proper contact, which reduces braking performance and can cause the new pads to wear out prematurely.
- Rotors are a critical part of the braking system, and they can warp or become damaged due to the heat and friction created during braking.
- When rotors are warped or damaged, they can cause vibration and reduced braking efficiency.

Does my car have disc or drum brakes?
You can tell if your car has disc or drum brakes by looking through your wheels: disc brakes have a visible, flat, shiny rotor and a caliper, while drum brakes have a solid, enclosed, round cover. Modern cars typically have disc brakes on the front and either disc or drum brakes on the rear, while many older cars use drum brakes on all four wheels.
How to identify disc brakes
- Appearance: Look through the wheel for a shiny, flat disc (the rotor) with a clamp-like unit (the caliper) sitting on it.
- Visibility: You can often see the rotor and caliper easily, especially on the front wheels of modern cars.
How to identify drum brakes
- Appearance: Look through the wheel for a solid, enclosed, round metal cover. You won't see a shiny disc or a caliper.
- Visibility: These are harder to see without a clear view through the wheel, and are often found on the rear wheels of some modern cars and the front and rear of older vehicles.
Other ways to find out
- Check your car's manual: The owner's manual will have specifications for your vehicle's brake system.
- Use your VIN: Enter your vehicle's VIN (Vehicle Identification Number) into an online VIN decoder or ask a dealership to find the exact specifications.
How do I know if I have mechanical or hydraulic disc brakes?
You can tell the difference between hydraulic and mechanical disc brakes by looking for a cable or a hydraulic line running from the brake lever to the caliper. Mechanical brakes use a cable, which you can see moving when you squeeze the lever, while hydraulic brakes use a thick, reinforced hose containing fluid.
| Feature | Mechanical Disc Brakes | Hydraulic Disc Brakes |
|---|---|---|
| Activation | Cable-driven | Fluid-driven |
| Connection | A metal cable runs from the lever to the caliper | A thick, reinforced hose runs from the lever to the caliper |
| Visual Cue | You can see the cable pulling the caliper when you squeeze the lever | You will see a hydraulic line, not a cable, and the lever may have a small reservoir |
| Performance | Less powerful and less precise; requires more hand and arm strength | More powerful and precise with a lighter feel; better for long descents |
| Maintenance | Needs more frequent adjustment as cables can stretch | Requires special tools to bleed out air from the fluid system |
