Purpose and vehicle placement

The presented caliper belongs to the Brake Calipers and Brackets category and is intended for installation on the rear axle on the right side. It is responsible for pressing the brake pads against the brake disc, stabilizing the braking force on the outer wheel on the passenger side. Proper placement on the vehicle is crucial for the correct operation of the system, which is why this component should only be used in the position intended by the manufacturer.

Original origin and fitment for Audi

The caliper was designed by Audi for the 8V generation A3 and S3 models, which translates into a precise fit with the carrier, disc, and other braking system components. The original design ensures:

• maintenance of the factory mounting geometry to the steering knuckle and carrier,
• proper cooperation with a brake disc of a specific diameter and thickness,
• compatibility with the stock braking system hydraulics.

As a result, installation is predictable, without the need for modifications or additional adapters, and the entire system maintains parameters similar to the factory configuration.

Technical and functional characteristics

The Audi A3 S3 8V Brake Caliper Rear Right O/S Wheel Braking Unit works with a 310x22 mm ventilated disc, which is a typical solution for more powerful braking system versions in this generation. The caliper design has been developed to ensure:

• stable pad pressure across the full operating range of the system,
• even wear of friction linings,
• adequate resistance to thermal loads during intensive braking.

As a rear axle component, the caliper contributes to the balance of braking force between the front and rear of the vehicle, which is important for both safety and the operation of assistance systems such as ABS or stability control.

Condition, application, and benefits of choosing a used part

The offered item is in Used condition, meaning it comes from dismantling, and its main advantage is the preservation of the original design while reducing repair costs compared to a new part. Such a choice is particularly beneficial when you want to:

• maintain the factory character of the Audi A3 / S3 8V braking system,
• limit expenses while maintaining the original specification,
• use a component with known origin and predictable fitment.

Before installation, standard workshop verification and replacement of consumables (pads, discs, brake fluid) are recommended in accordance with the vehicle manufacturer's service procedures to fully utilize the potential of this component.

Technical support and selecting the right caliper

The selection of a rear right brake caliper for a specific version of the Audi A3 or S3 8V should take into account the braking system configuration, disc diameter, and vehicle equipment. In case of doubt, it is worth using the OEM part number or interchangeable numbers visible in the technical specification to confirm full compatibility with the given car. This minimizes the risk of mismatch and ensures that the component will work with the existing hydraulic installation and braking equipment.
