Purpose and vehicle placement

The presented caliper belongs to the Brake calipers and carriers group and is intended for installation on the rear axle, on the right side. It is responsible for evenly pressing the pads against the disc, stabilizing braking force, and maintaining the proper geometry of the rear axle system. The vehicle placement is factory-defined, which facilitates part selection and minimizes the risk of errors during installation.

Technical and functional characteristics

The Audi S5 F5 Rear Brake Caliper Housing Brake Unit Right O/S has been designed to work with a 330 mm diameter and 22 mm thick disc, which allows for effective heat dissipation and stable operation under dynamic driving conditions. The body construction ensures adequate rigidity, while the guide and mounting system allows for smooth pad movement and even wear of the friction linings.

Key advantages of this solution include:

• factory fitment for the Audi S5 F5 brake system on the rear right axle,
• operating characteristics designed for the 330x22 disc,
• stable pad guidance and repeatable braking force,
• construction prepared for use with standard mounting hardware.

Original origin and benefits of using a pre-owned component

The caliper comes from the Audi production line, which means it maintains factory manufacturing tolerances, mounting geometry, and operating parameters. A used component of this class allows for lower repair costs compared to a new part, while maintaining consistency with the original brake system design. For many users, this is a reasonable compromise between price and quality, especially in the case of high-performance models such as the S5.

Preparation for installation and service application

Due to its factory origin, the caliper is structurally prepared for installation in place of the original component on the rear right axle of the Audi S5 F5. During replacement, standard service procedures are recommended, such as checking the condition of the disc, pads, and brake lines, as well as bleeding the system after work is completed. Following the proper installation procedure allows you to fully utilize the potential of this component and maintain predictable vehicle behavior during braking.
