Purpose and fitment

The presented carrier belongs to the Brake Calipers and Carriers group and has been designed specifically for the Audi A4 B7 generation model. The component is intended for installation on the rear axle on the right side, which guarantees correct alignment with the brake disc and compatibility with the original caliper and mounting hardware.

Its factory origin ensures compliance with the vehicle manufacturer's requirements regarding rigidity, dimensional tolerances, and the placement of mounting points. As a result, the carrier provides a secure base for the caliper to operate, minimizing the risk of uneven pad wear or improper contact with the disc.

Construction and function in the brake system

The carrier plays a crucial structural role – it stabilizes the caliper relative to the wheel hub and disc, transferring the loads generated during braking to the vehicle's suspension. The appropriately selected material and body shape ensure high resistance to mechanical and thermal loads typical of intensive road use.

Precisely machined guide pin sockets and contact surfaces with the caliper allow for smooth movement of the working elements, which promotes even pad pressure. Proper alignment of the carrier relative to the disc reduces the risk of vibration, noise, and overheating of one of the pads, which has a direct impact on braking stability and predictability.

Characteristics of the used component

The offered carrier comes from dismantling and is classified as a used part. This type of component, provided that its technical condition is properly verified, represents a reasonable compromise between cost and quality, especially in the case of structural elements with a simple design, such as caliper carriers.

In practice, this means that with proper installation and the use of new consumables (pads, discs, guide pins, dust boots), it is possible to obtain a fully functional, safe brake system while maintaining a favorable level of service costs.

Installation and maintenance tips

Before installation, it is recommended to thoroughly clean the contact surfaces with the steering knuckle and check the condition of the threads and guide pin sockets. Replacing sliding elements, applying appropriate high-temperature grease, and inspecting the discs and pads allow you to fully utilize the carrier's potential and reduce the risk of subsequent issues with caliper operation.

Due to the importance of the brake system for driving safety, installation should be performed by an experienced mechanic, adhering to the tightening torques recommended by the vehicle manufacturer as well as procedures for bleeding and checking brake operation after the work is completed.
