Brake pads are an integral part of your car's braking system that use friction to change kinetic energy to thermal energy to slow the car. You will likely need to change your brake pads at some point.
The cost of new brake pads will depend on the make and model of the vehicle and the type of pad. The first indication that you need new brake pads will be a high-pitched noise when you apply the brakes. If you hear a grinding noise, you need to replace your pads immediately.
There are 4 different types of brake pads: semi-metallic, non-asbestos organic, low-metallic non-asbestos organic and ceramic. However, according to Consumer Reports, brake pad manufacturers keep the exact content of their pads secret. Also, you do not need the most expensive pad for normal driving.
Not every type of pad is available for all vehicles. According to Auto Zone, a pair of semi-metallic pads cost £14.20 for a 2006 Mazda 3, a pair of ceramic pads cost £25.3, while the premium ceramic pads cost £38.3. Meanwhile, a pair of non-asbestos organic cost £14.90 for a 2004 Subaru Forester and a semi-metallic pair cost £24.0 for the same vehicle. According to Consumer Report, a pair of standard brake pads for a Chevrolet Tahoe cost £44, as of 2009. A pair is sufficient for two wheels. Meanwhile, superior ceramic pads for the Tahoe cost £78 a pair.
