Purpose and function in the brake system

The presented disc is a component mounted on the vehicle's rear axle, working in conjunction with brake calipers and pads to effectively reduce speed. The design, adapted for a 345 mm working diameter and 24 mm thickness, allows for efficient heat dissipation, which reduces the risk of overheating and loss of braking efficiency during intensive use.

Its original BMW origin means that factory dimensional tolerances are maintained, ensuring the disc works correctly with stock calipers, the hub, and safety systems such as ABS or traction control.

Benefits of using an original BMW brake disc

Using a used, original BMW brake disc allows you to maintain the consistency of the entire brake system according to the vehicle manufacturer's specifications. In practice, this means:

• secure fitment to the hub and caliper without the need for modifying mounting components,
• maintenance of predictable braking characteristics, consistent with factory calibration,
• the possibility of economical repair while retaining OEM components.

For many users, it is also important that the disc from this series is designed with appropriate rigidity and resistance to thermal deformation in mind, which promotes even pad wear and stable system operation in the long term.

Selecting the disc by OEM number and parameters

To correctly select this disc for a specific version of the BMW 5 or 6 Series, it is crucial to verify compatibility using the OEM number and the dimensional parameters assigned to the given brake system. In case of doubt, it is worth using the vehicle's VIN or consulting a mechanic to confirm compatibility with the specific rear axle configuration.

When selecting brake components, it can also be helpful to use technical guides. If you want to streamline the process of identifying parts by OEM number and vehicle data, the following material will be useful: guide to selecting the right car part by VIN and OEM number, which describes step-by-step how to minimize the risk of errors when purchasing used components.

Integration with other brake system components

The rear disc works directly with calipers, pads, and elements controlling system pressure. In the case of planned brake maintenance, it is worth considering a comprehensive approach to service, including checking the condition of calipers, hoses, and brake fluid. Well-chosen, original recycled components can significantly reduce repair costs while maintaining an appropriate level of safety.
