Disc Brakes are More Efficient

You are likely most familiar with disc brakes. They include a disc, or rotor, that turns with the wheel. There is then a caliper and brake pads that straddle the disc and place pressure on it to slow the car when braking.

Most modern cars will have disc brakes on at least two wheels if not all four. If there are only two wheels with disc brakes, they will be at the front of the car. The weight of the car is moved forward when braking and that means the front brakes must be extra efficient. Cars that are more expensive or are built for performance will likely have only disc brakes.

Drum Brakes are Found Most Commonly on Older Cars

Instead of a disc, drum brakes have a hollow drum that turns with the wheel. There is a stationary backplate with two curved brake shoes, each with friction lining that presses against the inside of the drum when braking.

You will find drum brakes most commonly on older and smaller cars. When you have two of each type of brake, the drum brakes will be on the rear wheels because those wheels take less of the car’s weight when braking.

What are Signs of Trouble with Your Brakes?

Given the importance of working brakes, it’s good to know the signs you may need a brake repair. A few key symptoms that your brakes are wearing out or need attention from an expert mechanic are:

• Delayed braking
• Squealing or grinding when braking
• Soft or spongy brake pedal

It’s important not to wait to get your brakes serviced if you suspect a problem. Especially if you notice grinding when braking, this means more damage may be caused if you wait to get it fixed.
