AI Technical Summary
Technical Problem
Existing disc brake systems suffer from non-uniform pressure distribution on the pad, leading to uneven wear of the friction material and reduced service life.
Method used
A thrust plate with a concave region and circumferentially extending flanks that elastically deforms to optimize pressure distribution on the pad, ensuring uniform contact with the support plate.
Benefits of technology
The thrust plate achieves a significant increase in uniformity of pressure distribution, enhancing the wear uniformity and extending the service life of the friction material.

Abstract
A floating brake caliper comprises a pad (2) and a thrust plate (4). The thrust plate (4) has a front surface (4a) having a concave region (12). In a rest configuration, the concave region (12) is at least partially separated from the rear face (6b) of the support plate (6) of the pad (2) by a gap (g); in a braking actuation configuration, the thrust plate (4) is elastically deformed and the concave region (12) is at least partially abutting the rear face (6b) of the support plate.
