Claims7
A brake pad, for disc brakes, comprising
- a metal back plate provided with at least one indentation,
- wherein the at least one indentation is formed by several raised areas or depressions each having an approximately circular segment shape with an arcuate edge
- wherein the raised areas or the depressions are positioned such that the arcuate edge of each segment lies approximately on a common radius and
- wherein the indentation is characterized by a height or depth ranging from 0.5 to 1.0 mm;
- at least one friction layer which is attached to said metal back plate, and a third element comprising a material with lower heat conductivity than a heat conductivity value of the friction lining, wherein said third element is disposed in said at least one indentation.
