Purpose and compatibility

The presented caliper is designed for the rear right side of BMW F-series vehicles from the F20, F21, and F22 families equipped with N55 and B58 petrol engines in M Sport versions. This means that its geometry, mounting points, and operating range are adapted to the factory discs and pads used in these models, which translates into stable, predictable braking and the preservation of the factory system characteristics.

Technical characteristics of the caliper

The caliper belongs to the Brake Calipers and Brackets group, responsible for generating the clamping force of the pads against the disc. The design intended for operation in the BMW M Sport brake system ensures:

• properly selected braking force for the rear axle,
• stable operation under high thermal loads,
• compatibility with factory lines and mounts,
• maintenance of the proper balance between the front and rear axles.

Placement on the rear right side of the vehicle allows for the direct replacement of a damaged or worn component without the need for system modifications.

Benefits of using an original BMW caliper

Choosing an original BMW M Sport brake caliper primarily means maintaining factory braking parameters and the certainty that the component was designed with a specific model and petrol drivetrain configuration in mind. Using an OEM component allows for reduced repair costs while maintaining a high level of safety and driving comfort.

For owners of vehicles driven dynamically, especially in M Sport versions, the proper selection of the caliper is crucial for vehicle stability during braking, the operation of assistance systems, and the even wear of pads and discs.

Professional selection and operation

Before installation, it is recommended to verify compatibility with the specific vehicle equipment version and to check other brake system components, such as discs, pads, and lines. A correctly selected and installed caliper on the rear right axle allows for the restoration of full brake system efficiency, which is particularly important in cars with powerful N55 and B58 petrol units.
