Preventing squeal

In order to prevent noise during braking, highly effective primary and secondary measures are both used on brake pads.

Primary measures act directly on the point of friction. Here, the main issue is optimization of the materials used for the relevant parts. In many cases, ATE uses the most effective variant and the best primary measure for noise suppression in the industry: the intermediate layer or underlayer!

On the other hand, secondary measures are intended to prevent the structure-borne sound which is produced from reaching the ear of the driver and pedestrians. Secondary measures can generally be divided into four groups: damping plates, damping foils, paints and greases.

The mixture makes the difference! 

ATE works with over 150 different mixtures of friction material to ensure that the optimal result is always achieved for any particular application. The friction materials are always being refined and developed for this purpose. The pad material consists of various components which each fulfill different functions during braking (also see the presentation on this subject in the download area).

Example of brake pad composition:

Labeling

Original ATE brake pads feature the ATE logo, ATE identification number, "ECE-R90" approval marking, pad mixture and production batch. 

In addition, the required fittings for installation are included with many ATE original brake pads. Otherwise, the corresponding pad accessories are clearly listed in the ATE catalog right next to the part number for the relevant ATE original brake pad.
