Vehicle Application and Placement

The presented caliper is designed for installation on the rear right axle of the vehicle. Its geometry, mounting bolt spacing, and caliper body design are tailored for the Audi S3 8P and Audi TTS 8J platforms, allowing for the preservation of factory braking characteristics and correct interaction with the vehicle's safety systems.

Selecting the correct caliper for the specific side of the vehicle is crucial for even brake force distribution, proper bleeding, and correct operation of the parking brake mechanism, if integrated into the design.

Construction and Operating Parameters

The caliper is designed to work with a disc of 310 mm diameter and 22 mm thickness, which is a typical configuration for sporty versions of Audi's compact models. This setup provides adequate friction surface area, thermal stability, and consistent braking performance under higher loads.

The caliper body is engineered for rigidity and resistance to deformation under hydraulic pressure. Proper pad guidance minimizes uneven pad wear, and the well-designed brake fluid channels facilitate effective bleeding and stable system operation.

Benefits of Using an Original Audi Caliper

• Factory fitment for the hub, caliper bracket, and brake disc specific to the S3 8P / TTS 8J.
• Seamless integration with the stock ABS/ESP system and brake force distribution between axles.
• Reduced risk of installation issues due to adherence to original geometry and mounting points.
• Ability to maintain the stock brake pedal feel and predictable braking force engagement.

As a component from the Brake Calipers and Brackets category, this model serves as a solid foundation for both standard repairs and restoring the original brake system configuration after modifications or an accident.

Condition, Verification, and Repair Application

The offered caliper is a used part, which significantly reduces repair costs while maintaining the original manufacturer's specifications. Such components are often chosen for rear axle servicing when a single caliper needs replacement without altering the entire system configuration.

Prior to installation, standard servicing procedures are recommended, including checking for leaks, assessing the condition of the guide pins, potential seal refurbishment, and installing new pads and discs matching the specified working dimensions. A caliper prepared in this manner can ensure stable and consistent performance over a long service life.

If you are planning a comprehensive repair or upgrade of the braking area in your Audi and require other components from the same group, such as additional calipers, brackets, or caliper carriers, please check the available parts in the Audi Brake Calipers and Brackets category.

Technical Support and Used Caliper Selection

When selecting a used brake caliper, it is crucial to ensure it matches the specific model, mounting side, and disc dimensions. Attention should be paid to structural compatibility with the existing system to avoid installation and subsequent operational issues.
