The brake caliper carrier is an important element of the braking system, a part of the mechanism that secures the brake pads. The task of the carrier is to create a smooth movement of the assembly by fixing the pads in certain areas of the carrier, and adhering them with the other side to the caliper. The caliper presses the brake disc and pad.

The functionality of the brake caliper carrier

A piston drives the TRW brand Carrier, brake caliper. The higher the pressure on him, the more she presses on the pads from the other side. Structurally, such a part is an all-metal product with holes for guide pins. An inner block is attached to the caliper body, and an external one is attached to the carrier. This design is simpler, but also less reliable. Considering that the caliper carrier, in contrast to the piston protected by the body, is open to external factors, it is more likely to corrode. This accelerates natural wear, especially in the guide pinholes. Over time, they develop and take on an elliptical shape. This contributes to the appearance of backlash and a decrease in the effectiveness of pressing the pads.
