You rely on your car’s brakes to stop the vehicle when you press on the pedal. A properly functioning system should be responsive and have minimal stopping distance to help you avoid accidents and road hazards. If you’re not familiar with how your car’s braking components work, here’s a closer look at the intricacies of the vehicle and how to tell if you need brake service.

A Guide to Car Brakes

How does the braking system work?

The system consists of several different components, including cylinders, brake pads, rotors, calipers, fluid, and hoses. Stepping on the pedal causes the cylinders to distribute fluid through hoses to the calipers to activate the brake pads. The pads then apply pressure to the rotors, creating the force required to stop the car.

How do I maintain the system?

The multiple parts of the system have varying maintenance requirements. Monitoring the level of brake fluid should be a priority. The brake fluid reservoir has markings that indicate the right level. If you replenish the fluid yourself, make sure to use the one recommended by the manufacturer.

You should also pay attention to the thickness of the brake pads-they should be at least 5mm thick-which wear down over time from the constant friction. While you may be able to see the pads without removing any parts, you may need a mechanic to take off the wheels first. 

You can also have a professional perform an inspection, during which they can check the hoses and cylinders for brake fluid leaks. Additionally, they can examine the rotors to ensure they’re smooth. 

What’s the life span for brake pads and rotors?

The average life span for pads is between 30,000 and 70,000 miles. Rotors can last up to 210,000 miles, but their longevity largely depends on whether you keep up with maintenance. For example, having the pads replaced before they wear too thin will prevent the rotors from grinding against metal when you apply the brakes, preserving them for longer.

How can I tell if I need brake service? 

There are several different indicators that your system requires the attention of a professional. One common sign is an unusual noise when you apply the brakes. Squealing often indicates that the pads are too thin and need replacing. Grinding can either mean that you need new pads or that the caliper is getting stuck on the rotor when you push the pedal.

If the pedal vibrates when you step on it, the rotors are likely misshapen or worn down. In this case, a mechanic may be able to fix the problem by turning the rotors so that the friction is applied to a smooth surface when you activate the system.
