Audi S3 8P Rear Brake Caliper Housing Carrier Right O/S 310x22mm 8J0615424E

Audi S3 8P Rear Brake Caliper Housing Carrier Right O/S 310x22mm is an original component from the Brake Calipers and Carriers group, designed to work with a brake disc of a specific diameter and thickness. This is a solution for users who expect precise caliper guidance, stable brake system operation, and the preservation of factory vehicle parameters. Using an OEM component allows for a technically correct repair without the need for aftermarket alternatives with uncertain tolerances.

Purpose and function in the brake system

The presented carrier is dedicated to installation on the rear, right axle, where it is responsible for the rigid and axial guidance of the caliper relative to the disc. A correctly selected carrier ensures:

• stable positioning of the brake pads relative to the working surface of the disc,
• even wear of the friction linings,
• repeatable braking performance under loads typical for the S3 version,
• maintenance of system geometry consistent with the manufacturer's design.

Thanks to its fitment for a specific rear axle configuration, the carrier works with a disc of a specific diameter and thickness, which is important for maintaining the proper clearance between the caliper and the rim.

Compatibility with rims and installation aspects

The element has been designed with a brake system in mind that works with rims of a specific width, which limits the risk of the caliper colliding with the rim. This is particularly important in cars with sporty characteristics, where larger discs and more elaborate calipers are used.

During installation, it is worth paying attention to:

• checking the condition of the guide pins and the contact surfaces with the steering knuckle,
• correct tightening of the mounting bolts in accordance with the vehicle manufacturer's recommendations,
• checking the operating clearance between the caliper, disc, and rim after assembling the system.

A properly installed carrier minimizes the risk of vibration, noise, and uneven pad wear, which translates into stable operation of the rear brake system.

Benefits of using an original caliper carrier

Choosing an original caliper carrier for the Audi S3 8P allows you to maintain the factory operating parameters of the brake system, including the appropriate stiffness and mounting geometry. Compared to random aftermarket replacements, the OEM component ensures:

• precise fit to the steering knuckle and caliper,
• compliance with the factory spacing and disc diameter,
• predictable behavior during intensive braking,
• easier diagnostics and service in the future.

A used original element is often a reasonable compromise between cost and quality, especially in high-performance cars where brake system stability is crucial for safety.

Condition of the element and use in service practice

The product is offered as a used part, which in workshop practice allows for a significant reduction in repair costs while maintaining the original specification. This type of carrier will work well both when replacing a damaged carrier after a collision or corrosion, and when completing a brake set for a conversion to a larger disc as part of a rear axle upgrade.

To better plan your repair and consciously choose used brake system elements, it is worth reading the guide: Brake calipers under the microscope: How to effectively reduce brake system repair costs by choosing proven recycled parts. The article explains what to look for when selecting components and how to safely use recycled parts.
