Is it time to change brake pad now ?

A number of factors affect the useful lifespan of brake pads. While brake pads are generally designed to take extensive braking force and heat, they are worn off with extended usage over time. Although most car manufacturer claim that the original brake pads can last for more than 50,000km, there is no one standard number that can be guaranteed as there are various factors affecting the lifespan of the brake pads.

Friction Material Composition

In general, there are 3 types of friction materials used in brake pads; organic, semi-metallic and ceramic. Organic brake pads are generally quieter and are gentler on the brake disc rotors. Semi-metallic brake pads are able to withstand higher temperature range but can cause more wear on the brake disc rotors. Ceramic brake pads on the other hand have usually a longer lifespan but there could be a potential noise issue.

Friction Material Formulation

Within each friction material composition, there are different raw materials added to form the ‘cake’. The proportions of raw materials, coupled with the right combination of time, heat and pressure affects the performance as well as the wear rate of the friction material.

Driving Style

For the heavy footed who prefers to stop at the last possible minute or frequently stopping at high speed, brake pads will be worn off much faster. Gradual stopping with anticipation will help to extend the usage of brake pads

Driving Environment

In driving conditions where there are many stops and turns, the increase in frequency of stepping on the foot pedal is inevitable. The increase wear on brake pads is compounded with driving in hilly terrain. Except for driving style, many factors are not within the drivers’ control. However the driver can choose to use a reputable brand that has the proven formulation to suit their driving demands.
