Patent ID: 8100233

Claim:
Disk brake vibration damper comprising a piston ( 3 ) intended to apply an axial braking pressure (F 1 ) to a brake pad ( 2 ), the piston having a face ( 33 ) engageable with the brake pad, characterized in that the damper also comprises a cylindrical element ( 4 ) having a face ( 40 ) engageable with the brake pad and a cylindrical peripheral surface ( 41 ), the peripheral surface having thereon a layer of a supple material ( 5 ) which exhibits properties of adhesion with the materials of the piston and of the cylindrical element, said cylindrical element ( 4 ) being positioned inside an axial cavity ( 30 ) of the piston with said layer of supple material ( 5 ) in contact with an interior wall ( 31 ) of the cavity of the piston ( 3 ), the cylindrical element ( 4 ) sliding in said cavity ( 30 ) of the piston as the face of the piston moves into and out of engagement with the brake pad.
