Purpose and compatibility with Audi models

The presented brake caliper is designed for Audi A5, S5, Q5 Sportback, and S4 B9 generation models, where it integrates with the rear braking system. The vehicle placement is specified as the rear right side, allowing for precise selection of the component for the correct mounting position and avoiding errors when sourcing parts.

Thanks to its factory design, the caliper works with the standard brake discs and pads intended for these versions, which promotes stable system operation and simplifies future maintenance tasks.

Construction and function in the braking system

The brake caliper is responsible for converting hydraulic system pressure into clamping force of the pads against the disc, which is why its technical condition has a direct impact on braking efficiency. The OEM design ensures:

• proper guidance of brake pads in the carrier,
• correct geometry relative to the disc,
• compatibility with factory brake lines and mounts.

An original salvaged brake caliper is a solution that allows you to maintain the integrity of the entire braking system without the need for adapters or modifications.

Benefits of choosing an original used brake caliper

Choosing a used brake caliper for an Audi is a reasonable compromise between repair costs and maintaining factory specifications. This type of component:

• maintains the original braking performance characteristics,
• reduces the risk of fitment issues typical of aftermarket parts with inconsistent quality,
• allows you to optimize your repair budget while maintaining a high level of safety.

Before installation, standard service procedures are recommended – checking for leaks, ensuring the free movement of guide pins, and assessing the condition of working surfaces – to fully utilize the potential of the part.
