A brake pad having a layer of friction material integrally moulded with a backing plate, wherein the backing plate having an electroconductive member moulded within a plate of a fibre-reinforced polymer resin, the electroconductive member extending along a plate direction, the backing plate having a front surface forming an interface with a rear surface of the layer of friction material, wherein the electroconductive member is profiled in a thickness direction of the backing plate to provide at least one projection extending towards the interface or into the layer of friction material and arranged to function as a wear indicator for the brake pad. Also disclosed are methods for manufacturing the brake pad.
A brake pad comprising a layer of friction material integrally moulded with a backing plate, wherein the backing plate comprises an electroconductive member moulded at least partly within a resin plate of a fibre-reinforced polymer resin, wherein the electroconductive member comprises a plate extending along a plate direction of the backing plate, the backing plate having a front surface forming an interface with a rear surface of the layer of friction material, wherein the electroconductive member is profiled in a thickness direction of the backing plate to provide at least one projection extending towards the interface or into the layer of friction material and arranged to function as a wear indicator for the brake pad.

A brake pad comprising a layer of friction material integrally moulded with a backing plate, wherein the backing plate comprises an electroconductive member moulded at least partly within a resin plate of a fibre-reinforced polymer resin, the electroconductive member extending along a plate direction of the backing plate, the backing plate having a front surface forming an interface with a rear surface of the layer of friction material, wherein the electroconductive member is profiled in a thickness direction of the backing plate to provide at least one projection extending towards the interface or into the layer of friction material and arranged to function as a wear indicator for the brake pad, wherein the electroconductive member comprises an electroconductive plate and the at least one projection comprises at least one deformed portion extending from the electroconductive plate towards the interface or into the layer of friction material, the deformed portion functions to enhance a bond between the electroconductive member and the resin plate of fibre-reinforced polymer resin, and the deformed portion is formed by punching a hole in the electroconductive plate to form a punched extension extending from the electroconductive plate towards the interface or into the layer of friction material.
