It is one of the most talked about parts of your car but do you really know what is happening with your car’s braking system?
We have an overview of our brake system here in your guide to your car’s brakes.

Your brakes are a major component of your vehicle and keeping your brake system in top condition is important. Not only for general maintenance of your car but also for safety reasons. So, lets talk about the components of your braking system. How it works and what potential issues you might face with them.

Car’s brakes System – Brake Pedal and Fluid

Your brakes are usually activated by pushing down on your foot pedal. Hydraulic fluid, known as brake fluid is then pressurised within the brake lines. This causes the pistons in your brake caliper to push outwards and activate the brake pad. It is important to keep your brake fluid in top condition and often you will see that a brake fluid flush will be recommended during your service. This will be because your brake fluid has been contaminated. This will reduce its ability to pressurise correctly, and thus affecting your braking capabilities.

Car’s brakes System – Brake Master Cylinder

As mentioned, your brake master cylinder is responsible for setting off the pistons which activate the brake pads. When a leak is present in the brake master cylinder, it often shows itself by causing your brake pedal to feel loose and/or pull down to the floor. This can present major issues for your safety should the brakes not work, and also for your wallet with major repairs needed. Keep an eye out for any concerns for your brake master cylinder in your service reports. Tackle these issues early to help avoid potential safety or financial concerns.

Car’s brakes System – Brake Pads

Your brake pads are made of a friction material such as ceramic, which is attached to a metal plate. These plates sit on either side of the brake disc and when pressure is applied to the pistons (as above). The pads essentially clamp down onto the disc which slow you down. Over time the ceramic pad wears down and this is a normal part of your wear and tear of your vehicle. During your service, your technician will check the thickness of these pads to ensure they are still within acceptable thickness. Once they are below the minimum thickness, we will suggest that you have these replaced.

Car’s brakes System – Brake Rotors

Your rotors are disc shaped and rotate with acceleration causing your wheels to turn. When your brakes are activated, the pad will press on either side of your rotors which causes you to slow down. Your rotors will wear down and get grooves with normal wear and tear of your brakes. When you get your service and we check the thickness of your brake pads, we will also check the condition of your rotors. Most of the time we will recommend machining your rotors when you replace your pads, to ensure that a smooth surface is created, extending the life and effectiveness of your new pads. Once your rotors reach minimum thickness, they will need to be replaced.


Car’s brakes System – Brake Drum & Shoes

Some other variations of your brakes system that you may come across are brake drums and shoes. Simply put, the the drum rotates within the wheel much like the rotor does. Inside the drum is the the brake shoes with a friction pad and when brake pressure is applied these shoes push outwards against the drum edge causing the car to slow down. This brake system will wear down with general use much like your disc brake system.
