Here you will find useful information and important tips relating brake repairs.
Important safety note
1. Steel pad base plate
2. Pad adhesives
3. Intermediate layer
4. Friction material
5. Secondary measures
Braking noise is caused by friction value fluctuations during braking. Secondary measures are intended to suppress high-frequency vibrations and therefore prevent noise. These measures can vary from vehicle to vehicle depending on the structure of the brake system. In some brake pads, several measures may be used simultaneously.
These include a lacquer coating, textile surface, adhesive film, or additional damping plate.
Chamfers are tapers in the friction surface individually developed for each brake pad. The final contour of the chamfer is determined through extensive driving tests as well as on test stands.
An additional damper weight mounted on the brake pad increases the overall mass of the component, thus lowering its resonant frequency. Depending on the configuration and position of the weight, this vibration damping can be used for either targeted noise reduction or complete noise elimination. The design of the weight may vary depending on the vehicle manufacturer and the brake system.
Depending on the size and shape of the brake pad, cracks may form in the friction lining as a result of temperature-based expansion. Slots are milled into some brake pads to prevent these cracks. These also reduce noise and hold brake pad wear particles.
These brake pads are adapted to the installation position in the brake calliper and the running direction of the brake disc through special secondary measures such as chamfers or damping plates. A crescent-shaped recess on the rear alters the press-on position of the piston-side brake pad. This reduces noise and improves the comfort characteristics. The running direction is indicated by an arrow. Special installation instructions are provided for the respective brake pads.
