It’s also important to give your pads a worthy grade of caliper to sit in. Larger calipers with a greater number of pistons are able to deploy a greater amount of force onto the pad, which in turn aids pad performance against the rotor. How to choose the best rotors Brake discs are a lot more resilient than brake pads as brake discs are constructed of cast iron in most circumstances. When it is time to change your brake discs it is recommended that you also get your brake pads changed at the same time. This is so the braking system is fully rejuvenated and you get the most out of your brakes. Related: Do I need new brake pads? Are worn brake discs an MOT failure?

How do I choose new brake pads?
Slowing down is just as important as speeding up. Here are some of the best brake pads and rotors on the performance aftermarket. There are some lightly uprated drums setups out there. The most common have grooves on the friction surface to help dissipate heat, or shoes with a softer performance compound. To be fair though, in the case of front brakes at least, you only find drums on the seriously old school classics. Even then many simply choose to upgrade to rotors. Brake bias When the driver steps on the brake pedal, the power is amplified by the brake booster (servo system) and changed into a hydraulic pressure (oil-pressure) by the master cylinder. The pressure reaches the brakes on the wheels via tubing filled with brake oil (brake fluid). Over time, these can build up to produce a fine dust which is corrosive to the paint on your car’s wheels. Therefore, this dust needs removing, but how can you do it without scratching your car’s paintwork?

The brake disc (or rotor) is the rotating part of a wheel’s disc brake assembly, against which the brake pads are applied. The material is typically gray iron, a form of cast iron. The design of the discs varies somewhat.Calipers are of two types, floating or fixed. A fixed caliper does not move relative to the disc and is thus less tolerant of disc imperfections. It uses one or more pairs of opposing pistons to clamp from each side of the disc, and is more complex and expensive than a floating caliper. At Germany's Argus Motoren, Hermann Klaue (1912-2001) had patented [9] disc brakes in 1940. Argus supplied wheels fitted with disc brakes e.g. for the Arado Ar 96. [10] The German Tiger I heavy tank, was introduced in 1942 with a 55cm Argus-Werke disc [11] on each drive shaft. Upgrading the system revolves around increasing the bite of the pads (through the choice of compound), the clamping force that can be applied by the calipers and the leverage on the disc. Not forgetting, the ability of the whole lot to effectively dissipate the heat produced. Brake Rotor / Disc sizes Of course, the exact answer to the question will differ between cars, and frankly, between driving styles too. That being said, most brake rotors are due a replacement roughly every 50,000 to 75,000 miles. In the USA, the average driver travels just shy of 14,000 miles per year, while in the UK, that figure stands at around 7500 miles. In practice, that means that in America, cars will get through a set of rotors every 3-5 years, whereas British drivers will need to change them approximately every 6-10 years (though the upper estimate seems a bit optimistic to us).
