Audi RSQ3 F3 Brake Caliper Housing 374X36mm Front Left N/S 83A615107B

Audi RSQ3 F3 Brake Caliper Housing 374X36mm Front Left N/S is an original component from the Brake Calipers and Brackets group, designed for use with a large 374x36 mm brake disc. It serves as a solid foundation for rebuilding a high-performance, sporty front braking system, ensuring correct mounting geometry and stable brake pad guidance.

Purpose and vehicle placement

The presented caliper housing is designed for installation on the front left side of the vehicle, in the immediate vicinity of the wheel hub. The construction is adapted for a large 374x36 mm disc, which allows for effective heat dissipation and stable operation of the braking system in a high-performance car.

The precise placement of mounting points ensures correct alignment relative to the disc, and the properly shaped guide pin sockets allow for smooth operation of the caliper's moving parts once assembled.

Technical characteristics of the housing

The caliper housing is the main load-bearing element of the entire braking mechanism on this side of the vehicle. It is responsible for:

• maintaining proper system rigidity during intensive braking,
• stable guidance of brake pads relative to the disc,
• safe transfer of braking forces to the steering knuckle and suspension.

Thanks to the design intended for a large 374x36 mm disc, the housing is prepared for operation under conditions of increased thermal and mechanical load, typical for dynamic driving in an RS model.

Condition of the component and workshop application

The product is offered as a used brake caliper housing, which allows for an economical rebuild of the braking system while maintaining the original geometry and fitment to the Audi steering knuckle. This type of component is particularly useful in situations where mechanical damage has occurred (e.g., after a collision or overheating), and it is necessary to replace the housing itself while reassembling the caliper with new service parts.

In workshop practice, the housing can be used as a base for regeneration – after proper surface preparation, thread inspection, and the installation of new seals, pistons, and guide pins, it allows for the restoration of a functional, high-performance front caliper.

Benefits of using an original Audi housing

Using an original caliper housing in an Audi RSQ3 F3 ensures:

• factory fitment to the front left steering knuckle and hub,
• compatibility with 374x36 mm disc dimensions without the need for modifications,
• preservation of the braking system's performance characteristics as intended by the manufacturer.

For users who value the technical consistency of the entire braking system, this is a solution that allows for maintaining near-factory parameters while reducing costs compared to purchasing a new complete unit.
