The importance of brake maintenance.

The brakes on modern vehicles operate as a hydraulic system. This means that they are controlled and operated by fluid.  When you press your foot on the brake pedal, the master cylinder pushes brake fluid through the brake lines into the calipers, which then squeeze the brake pads on to the brake rotors.  The brake rotors spin simultaneously with the wheels and friction applied to them slows the vehicle down.


There are 3 parts of the braking system that require regular maintenance in order to operate at their full capacity – the brake pads, the brake rotors and the brake fluid.


Brake pads operate by applying pressure to the brake rotor and using friction to slow the car down. Due to the nature of the design they wear and need to be periodically replaced. A car with worn brake pads will brake poorly and be unsafe, so Tunehouse checks the brake pads on every car that comes in for a service. There are different brake pads constructed with different compounds for different driving styles. We can help you decide on which is best suited for you and your car.


Brake rotors wear too, though they last longer than brake pads. Over time the surface of the rotors will develop grooves from the friction pressure of the brake pads. They can be periodically resurfaced in order to flatten out the surface area again but will eventually need replacing. We offer high performance upgraded rotors as an optional replacement to improve the braking ability of your car.


Brake fluid is what brings the whole system together. It is what applies the pressure on the calipers to squeeze the brake pads against the rotors. It is very important to replace the fluid regularly in order to maintain optimum brake capacity. This is because brake fluid is hygroscopic, meaning it absorbs moisture from the atmosphere. Over time this moisture content in the brake fluid builds up and has two effects – firstly, the brake fluid simply cannot work efficiently and will cause a soft feel under braking, and lacklustre braking performance. In an emergency situation this can affect your cars ability to pull up to a stop quickly. Secondly, over a longer term the moisture can cause rust in the braking system, leading to a handful of potential issues including blocking the flow of brake fluid.  As these issues can inhibit the safety of your car, we suggest taking no risks when it comes to your braking system.

If your car needs a brake inspection or you’re due for a service and want complete peace of mind, call Tunehouse on (02) 9557 4000 or email us at to find the next available appointment. At Tunehouse we have the expertise and the equipment to diagnose and service your brake system.
