    A friction pad is placed against the disc and used to brake any vehicle. The friction between the disc and the pad causes heat to spread over the brake disc, which causes the car to slow down. This is also true for brake drums that have the brake shoe pressing against them. The brake drums heat up, causing the car to slow down again.

    Starting under your foot the pressure you apply to the brake pedal is transferred to the brake servo, this utilises engine power to increase the pressure and ensuring you can still feel your leg after a long journey!

    How is the pressure transferred to the friction (brake) pads? The secret to brake fluid is in the brake pipe, which runs from the servo and the brakes. Fluid is used as cables would require constant adjustment due to stretching from the heat and constant use.

    As mentioned the heat is dissipated from the pad by the brake discs. For improved dissipation vented brake discs have a central channel that increases the surface to air ratio of the disc and gives more efficient cooling. Drilled and vented discs increase the air ratio, prevent a build up of gases and keep the pads in a clean condition. You can fit larger discs to improve the braking performance of high-performance cars, but you might need to use different wheels.

    Brake pads are obviously an essential part in stopping your car and the higher the friction the better the performance. Fast road pads give a good compromise between standard and racing pads with some generating zero pads. Remember that regardless of the pads your driving style will play a large part in the wear on the pads and discs.

    ABS prevents lockups when you brake hard. It also allows you to steer your car, but ABS will cut in more.

    Brake upgrades

    Braided hoses made of stainless steel resist bending and loss of pressure at the pad ends. They also look better and theoretically last longer. Get a complete set and do both the front and the back.

    You have many options to upgrade your cars braking system. The fitting of bigger discs is an upgrade that could be a fairly simple option. For example, if you have a family car with small discs, you can visit your local breaker to get parts or order online for a performance version. It is common for small cars to share brake parts with their bigger brothers. A little bit of research can lead to some surprising results.

    General Care of Your Brake System

    At least once per year you need to give your brakes a once over. Start by checking your pads and discs for wear and tear. The discs should not have a ridge on the edge due to excessive wear, thin discs can warp under immense heat conditions. You should check your pads for wear, as they can eat into your discs.

    Brake fluid levels should be changed at least once per year but no longer than every two years.

    It is important to check your brakes after you have driven through standing water. This will help to eliminate any grease and water buildup.

    I hope that you found this useful. It’s important to pay attention to your brakes in order to safely stop your car.
