Purpose and vehicle placement

The presented caliper is designed to operate on the rear right side of the vehicle, which is crucial for the correct distribution of braking force and the operation of the handbrake mechanism (if present in the given system). Proper placement on the vehicle minimizes the risk of incorrect installation, facilitates the selection of brake pads, and ensures correct cooperation with the brake line and carrier.

Selecting a caliper dedicated to a specific side of the vehicle is important for:

• correct system bleeding (bleeder screw orientation),
• proper routing of the brake line,
• compatibility with suspension and wheel hub geometry.

Technical and functional characteristics

The brake caliper from this series was developed by the Audi brand as an original part, which translates into precise fitment to the hub, disc, and carrier. The design provides stable guidance for the brake pads, even pressure on the disc, and resistance to thermal loads typical for the rear axle of a mid-size car.

Key functional features include:

• compatibility with the factory Audi A4 B6 brake system,
• maintenance of serial braking force parameters on the rear axle,
• possibility of using standard brake pads and discs intended for this model.

Thanks to the preservation of the original geometry, the caliper works with factory suspension and hub components, which reduces the risk of uneven pad wear and vibrations during braking.

Original origin and used condition

The element comes from the Audi parts line, which means compliance with factory dimensional and material tolerances. The used condition of the component allows for a significant reduction in repair costs compared to a new replacement, while maintaining the operating characteristics intended by the vehicle manufacturer.

Choosing an original, used caliper is particularly beneficial in situations where:

• you want to maintain the serial brake pedal feel,
• you want to avoid problems with fitting aftermarket parts of uncertain quality,
• you are planning a brake system repair that is economical but technically correct.

Benefits of use in Audi A4 B6

Installing a caliper dedicated to the Audi A4 B6 on the rear right axle allows for maintaining the consistency of the entire brake system. Proper fitment to the hub, disc, and pads reduces the risk of overheating, uneven wear, and a decrease in braking efficiency. This solution is particularly recommended for:

• repairs after guide pin or piston seizure,
• system regeneration after long-term operation,
• restoring full brake efficiency after mechanical damage.

If you are planning a comprehensive repair or upgrade of the braking zone in your Audi and need other elements from the same group, such as additional calipers, carriers, or brackets, check the available parts in the Audi brake calipers and brackets category.

Summary

Audi A4 B6 Rear Brake Caliper Housing Right O/S is a sensible choice for drivers who expect compliance with factory specifications, proper fitment, and predictable brake system operation. The used, original component allows for combining service cost control with the maintenance of braking parameters designed by the vehicle manufacturer, which has a direct impact on safety and driving comfort.
