Purpose and compatibility

The offered brake disc has been designed specifically for BMW F40, F44, F45, F46, and F48 series models, intended for the rear axle on either the left or right side. This solution facilitates maintenance – a single reference can serve both sides, reducing the risk of errors during part selection and inventory management.

Due to its design in accordance with BMW factory standards, the disc works with original calipers, pads, and mounting hardware, maintaining factory braking force characteristics and vehicle stability during ABS and traction control system operation.

Technical and functional characteristics

As an element in the Brake discs category, the product is responsible for the effective dissipation of thermal energy generated during braking and maintaining a constant coefficient of friction between the pad and the working surface. The properly selected geometry and mass of the disc limit the risk of overheating, thermal cracks, and vibrations felt on the bodywork.

The placement on the rear axle on the left or right side allows for maintaining the symmetry of the braking system, and the proper balancing of the disc minimizes radial and axial runout. This, in turn, translates into even pad wear, stable system operation, and a reduction in noise and vibrations during braking.

Condition and service application

The item comes from dismantling and is offered as a used BMW brake disc, which is an economical solution for maintenance repairs or temporary replacement in fleet and private vehicles. This type of part can be used, among other things, as a replacement in the event of mechanical damage, uneven wear on one side of the axle, or restoring system efficiency after a collision.

Before installation, a standard service procedure is recommended: checking the working thickness, friction surface, runout, and the condition of the hub and pads, so that the entire braking system operates within a safe parameter range. Proper installation and tightening according to the vehicle manufacturer’s recommendations are crucial for durability and comfort of use.

Safety and selection of brake system components

Selecting a used brake disc requires attention to compatibility with the specific body version and brake system of a given BMW, which is why it is worth using the OEM part number and interchangeable numbers visible in the technical specification. This allows you to avoid problems with installation, incorrect diameter, or disc offset, and ensures proper cooperation with calipers and pads.

If you want to organize the process of selecting and installing brake components in your car, a guide describing step-by-step how to assess the condition and safety of used components will be helpful – you can find it in the article Second-hand brake system: how to safely choose discs, calipers, and ABS?.
