Brake components for German cars have changed quite a bit over the past decade but the basic principals are still the same. Back when automobile manufacturers cared less about weight, fuel economy and performance, brake components were built to be heavy and strong. The excessive mass of the rotors allowed room for them to be machined or “cut” down, in order to smooth them out and reuse the rotors when the brake pads need to be replaced.
These days, rotors are designed to weigh less, increase performance and reduce fuel consumption. Automobile manufacturers have reduced not only the weight, but the overall thickness of the rotor. The reduction in unsprung mass is noticeable on modern cars and has achieved the goal the engineers intended. However, modern brake rotors cannot be machined as they are too thin to remove any high spots or groves that cause pulsation or squealing. This means that they now have to be replaced with each brake service.
Brake rotors and brake pads are not the only parts that are necessary to replace. It is extremely important to replace all anti-rattle clips and springs, as the old ones can lose their tension. When the brake components wear, they create dust that can cake up and even rust onto the brake components, causing them to stick, squeal or prevent the brake pads from releasing properly. That is why it is imperative that the technician cleans and files the brake pad carriers so they are not obstructed. Once the carriers are clean, they have to be properly greased. Using a high quality, moisture resistant grease will insure that the pads can slide properly. It is just as important that they can squeeze the rotor as it is that they release from the rotor, so they don’t drag and wear prematurely.
At Autohaus, we always replace brake components with OEM or better high quality replacement parts. We replace the brake rotors every time and properly clean the brake pad carriers using the correct grease. It is so important to use the right parts and install them correctly in order to save money and prevent squealing or premature wear in the future. Our expert technicians are familiar with the complexity of modern European cars and their braking systems.
