Abstract

Claims (21)

1. A brake pad assembly for a disk brake system, comprising

a back plate having a front side for facing a brake disk of the disk brake system and

a friction layer arranged on the front side of the back plate for contacting a friction surface of the brake disk,

wherein the back plate comprises a guiding protrusion configured to be slidably received within a guiding recess of a carrier of the disk brake system,

characterized by a shim configured to be arranged between the guiding protrusion ( 9 ) of the back plate and the guiding recess of the carrier, wherein the shim comprises a rubber layer and a stiff layer, characterized in that the stiff layer is a hard plastic sheet.

2. The brake pad assembly of claim 1 , characterized in that the rubber layer is arranged between the stiff layer and the guiding protrusion of the back plate.

3. The brake pad assembly of claim 1 , characterized in that a thickness of the rubber layer is at least 0.1 mm and at most 0.4 mm.

4. The brake pad assembly of claim 1 , characterized in that the shim is attached to a surface of the guiding protrusion of the back plate, wherein the surface of the guiding protrusion of the back plate is a side surface, a top surface or a bottom surface of the guiding protrusion of the back plate.

5. The brake pad assembly of claim 1 , characterized in that the shim is attached to the guiding protrusion of the back plate using an adhesive layer.

6. The brake pad assembly of claim 1 , characterized in that the shim comprises another rubber layer covering an outer surface of the stiff layer.

7. The brake pad assembly of claim 1 , characterized in that the shim comprises a non-stick coating layer forming an outer surface of the shim.

8. The brake pad assembly of claim 1 , characterized in that the shim is attached to the guiding protrusion of the back plate using bolts and/or rivets.

9. The brake pad assembly of claim 8 , characterized in that the bolts or rivets are recessed with respect to an outer surface of the shim.

10. The brake pad assembly of claim 1 , characterized in that the shim has a C-shape covering a side surface, a top surface and a bottom surface of the guiding protrusion of the back plate.

11. A disk brake system comprising a brake pad assembly according to claim 1 and further comprising the carrier, wherein the brake pad assembly is configured to slide with respect to the carrier in an axial direction upon brake application.

12. A brake pad assembly for a disk brake system, comprising

a back plate having a front side for facing a brake disk of the disk brake system and

a friction layer arranged on the front side of the back plate for contacting a friction surface of the brake disk,

wherein the back plate comprises a guiding protrusion configured to be slidably received within a guiding recess of a carrier of the disk brake system,

characterized by a shim configured to be arranged between the guiding protrusion ( 9 ) of the back plate and the guiding recess of the carrier, wherein the shim comprises a rubber layer and a stiff layer, characterized in that the stiff layer is a metal sheet, wherein the shim further comprises a hard plastic sheet.

13. The brake pad assembly of claim 12 , characterized in that the metal sheet covers an outer surface of the hard plastic sheet.
