Patent ID: 6955247

Claim:
A disc brake for a motor vehicle, comprising: two pads ( 11 ) each intended to cooperate with a lateral face of a disc ( 12 , 112 ) to be braked under the action of only one piston ( 14 , 114 ) mounted so that it is axially mobile, parallel to an axis of the disc ( 12 , 112 ), in a caliper ( 10 , 110 ) adapted to straddle the disc ( 12 , 112 ), said one piston ( 14 , 114 ) being adapted to cooperate at a support zone with one of the pads ( 11 ) facing it, each of said pads ( 11 ) comprising a metal support ( 18 ) carrying a friction lining ( 19 ), said metal support ( 18 ) being symmetrical with respect to a transverse plane of symmetry, which is perpendicular to it and which is parallel to the disc axis ( 12 , 112 ), the piston axis ( 14 , 114 ) being displaced with respect to said plane of symmetry by being at a transverse distance (d) from the latter, an anti-noise shim ( 21 ) being arranged between said one piston ( 14 , 114 ) and the metal support ( 18 ) and provided with a first opening ( 22 ) arranged at right angles with the piston support zone ( 14 , 114 ), wherein said first opening is adapted to displace a force of application of said one piston with respect to said plane of symmetry by a quantity greater than said transverse distance, and wherein the anti-noise shim ( 21 ) has a second opening ( 25 ), the first and second openings ( 22 , 25 ) being arranged symmetrically with respect to said plane of symmetry.
