Because brakes are such an essential part of a vehicle’s operation, every mechanic – be he/she a DIYer or a professional – should take servicing these life savers seriously. However, this does not mean that there aren’t some people who are willing to take shortcuts when it comes to replacing/serving this vital safety component. What we are referring to is the practice of “pad slapping’ which means replacing only the brake pads as opposed to replacing the pads and rotors when needed. At Autohaus we believe that a job worth doing is worth doing well. Here are some things you need to know about pad slapping and why we do not recommend this practice.
Reasons to Replace Rotors and Brake Pads
A car’s braking system is an intricate interplay of various machines parts that work in conjunction with one another. Neglecting one component of this system can compromise your vehicle’s ability to [...]
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 [...]
