Brakes are used for deceleration – by pressing the brake pedal, the piston in the main brake cylinder pumps brake fluid through a set of pipes and into the brake system for each wheel. There, one or more pistons in the brake cylinder (more commonly known within the automotive industry as a ‘caliper’) begin to push the brake pads, until they come into contact with the brake discs. As a result of the brake pads rubbing against the wheels, the vehicle will slow down and eventually come to a halt. During this process, the front wheels need to do approximately 70% of the entire braking process, that is why the front brakes are generally required to be sturdier than the rear brakes. Therefore, the technical condition of the front brakes is particularly important.
The whole braking process should remain both simple and safe, so long as the brake pads are in working order and not only perform their purpose well, but also rub against the discs without damaging them. However, if the pads are worn out, they can press against the wheel discs with differing forces, the result of which is almost guaranteed to be tragic. Therefore the condition of the brake pads must not be neglected, and they must be changed when brake pad wear is visible. Timely replacement of brake pads will cost a lot less than a more thorough repair of the brake disc, and possibly even the replacement of other elements of the braking system. So, step by step.
