How Automobile Brake Systems Work

Now that you know the history of brakes and different types of brakes, you might be wondering how the entire brake system works. In this second of a three part series on brakes we try to give some insight this.

Brake systems are what allow people to safely slow down their vehicles. Most of the time, drivers rarely have to deal with brake system failure. Usually, you just need to exchange the occasional brake pad or rotor. However, it is a good idea to know the full extent of your braking system to ensure you are aware when something is wrong with your brakes.

Automotive Braking System

Most modern vehicles use hydraulic systems for braking. The hydraulics are activated once the brake pedal is pressed. Once the pedal is pressed, brake fluid is sent through the brake hose. The hose connects to the caliper, inducing pressure on the caliper’s piston. The caliper squeezes the brake pads on the brake disc, producing friction that causes the vehicle to stop. The same thing happens with drum brakes as well. However, it is the brake shoes that cause the friction to the wheels instead of the brake pads. Both of these brakes rely on the conversion of kinetic energy into heat through friction to bring the vehicle to a stop.

Most brake systems focus on the front wheels of the car, due to the energy from the back wheels being pushed toward the front. As a result, most brakes are focused on the front tires instead of the back tires.

How Can You Tell Your Brakes are Failing

Now that you know the fundamentals of how brake systems work, it is time to go over the warning signs that your brakes are failing. When your brakes fail, it can lead to serious safety issues. Fortunately, your car will give clear signs that there are problems. Signs that your brake system is failing include:

• Squeaking and Grinding Noises
• Soft and Spongy Brake Pedal
• Vibration and Pulsation
• Brake Warning Light
• Reduced Stopping Power
• Burning Smell
• Fluid Leaks
• Uneven Braking

While you are driving, please keep a lookout for these signs so you can get your braking system inspected! If you ever run into brake trouble, you can always visit Mr. Muffler for a full brake inspection to make sure your car is in perfect condition!
