    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. The same applies for brake drums with the brake shoe pressed against it, heating up and again slowing the vehicle.

    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 does the pressure transfer to the friction pads (brake)? 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.

    The brake discs dissipate heat from the pads. Ventilated brake discs provide better heat dissipation and 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 play an important role in stopping your car. The higher the friction, the better it will perform. The fast road pads offer a compromise between racing and standard pads, with some generating zero. Your driving style and driving habits will have a significant impact on how the pads and discs wear.

    ABS helps to prevent lockups under heavy braking and allows you to steer the car but steering will reduce the braking efficiency as the ABS cuts in more.

    Brake upgrades

    Stainless steel braided hoses prevent any flexing and therefore loss of pressure at the pad end, they also look nicer and theoretically last longer too – get a full set and do the front and back at the same time.

    You have many options to upgrade your cars braking system. An easy upgrade is to fit larger discs. Take a standard family car for example with small discs – you could visit your local breaker or buy brake parts online for a performance model from the same vehicle. Small cars usually share the same brake parts than their larger brothers and just a small amount of research could turn up some surprises.

    General Care of Your Brake System

    You should inspect your brakes at least once a year. Check your brake pads and discs for wear. The edge of the discs shouldn’t have a ridge due to excessive wear. Thin discs can crack under extreme 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.

    One point to make is to test your brakes by applying them after driving through standing water to remove the water and grease build up.

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