Purpose and vehicle placement

The presented brake caliper is designed for use on the front left side of the vehicle, which is crucial for the correct distribution of braking forces and compatibility with the wheel hub and brake disc. The design is adapted for a braking system with a 345 mm disc diameter and 30 mm thickness, as well as a 5/112 bolt pattern, allowing for precise fitment to the specific axle configuration in Audi A6 C7 and Audi A7 4G models.

Technical characteristics of the TRW caliper

This version of the brake caliper utilizes solutions employed by TRW in factory Audi braking systems, ensuring stable operation under typical driving conditions. The construction is intended for use with a ventilated disc of the specified parameters, which enables efficient heat dissipation and maintains consistent braking force during intensive use.

The mounting geometry, position of the guide pin housings, and brake line connection points comply with factory standards, allowing the component to be integrated into the existing system without the need to modify other parts. This solution is particularly beneficial for post-accident repairs or replacing worn calipers on the front left side.

Benefits of using an original Audi caliper

Using an original brake caliper from this series allows you to maintain the consistency of the entire braking system with the vehicle's factory specifications. The main advantages of this solution include:

• maintaining the correct balance of braking forces between the left and right sides of the front axle,
• secure fitment to the steering knuckle, hub, and 345 mm diameter disc,
• compatibility with factory brake pads intended for this configuration,
• possibility of installation without interfering with the suspension or braking system design.

As a result, this used caliper can be utilized both as a replacement part in standard repairs and as part of restoring the complete braking system on the front left side.

Condition and service application

The offered item is in used condition, making it an attractive cost-effective alternative to new components while retaining the original Audi design. This type of caliper is suitable for professional workshops and informed users who are looking for parts consistent with the factory brake system design while aiming to optimize repair costs.

Before installation, a standard service procedure is recommended, including checking the working surfaces, guide pins, seals, and properly bleeding the system after installation. A correctly installed caliper restores full brake functionality on the front left side, ensuring stable performance during daily use.
