Whether you’re restoring a classic car or repairing your daily driver, brakes are an important component you may need to address. Without these parts, your car can’t stop effectively, putting your control and safety at risk. But while all brakes perform a similar function, not all types are the same. If you’re shopping for used car parts, it’s important to note the difference between drum and disc brakes, how they work, and why they might be preferred. Here are a few key details to know about each component.

Guide to Used Car Parts: Drum Vs. Disc Brakes

What Are Drum Brakes?

Drum brakes are what were commonly used on all cars prior to the 1970s. These parts consist of drum-shaped, metal housing that is affixed to the side of the wheel. When the brakes are applied, brake fluid causes two “shoes” within the drum to expand outward, creating friction that forces the wheel to come to a stop.

What Are Disc Brakes?

Disc brakes are a more recent innovation that is commonly found on the front two wheels of most cars. Instead of being housed in a drum, this brake system consists of a metal rotor disc, a caliper, and two brake pads. When vehicles are stopped, brake fluid stimulates the caliper to squeeze the brake pads against the rotor disc, causing the wheel to stop.

Which Brake Type Is Better?

If you’re considering which used car part is best for your vehicle, it’s important to note that both disc and drum brakes have their own distinct pros and cons.

In terms of stopping power, disc systems are generally more effective. Compared to drum systems, these brakes produce less heat, and therefore, do not experience reduced effectiveness—especially on steep inclines. While more costly than drum brakes, they can be inspected without having to remove the entire wheel and offer better control for drivers.

While disc brakes are more effective, drum brakes still offer unique value. For starters, drum brakes are fairly inexpensive, making them a more affordable option for rear wheels. They can also be replaced within just a few minutes. Drum brakes also integrate seamlessly within parking brake systems, where disc models require additional equipment to utilize this function.

Given these advantages and disadvantages, many drivers prefer having disc brakes in the front and drum systems on the back wheels.
