Purpose and vehicle placement

The presented brake caliper is designed specifically for installation on the rear right side of BMW G11 series vehicles. It is responsible for generating the clamping force of the brake pads against the disc, stabilizing the operation of the entire braking system on this axle. Correct placement on the vehicle is crucial for even distribution of braking force and proper interaction with safety systems such as ABS or stability control.

Technical characteristics of the caliper

The caliper belongs to the group of working components of the braking system, where both the body geometry and piston parameters are essential. The 44/24 designation refers to the caliper's operating configuration, which translates into appropriately selected braking force for the rear axle in luxury BMW sedans. The design provided by the manufacturer ensures:

• stable guidance of brake pads in the carrier,
• adequate working surface of the pistons,
• compatibility with standard discs and pads intended for this axle,
• proper cooperation with brake lines and bleeders.

By maintaining the original geometry, the caliper guarantees repeatable braking performance and proper force modulation during city and highway driving.

Original origin and replacement numbers

The component comes from the BMW production line as an OEM part, which means it was manufactured according to the manufacturer's factory quality standards. The caliper has a dedicated part number and assigned interchangeable numbers, which facilitates its identification in service catalogs and comparison with other variants used in a given model. The presence of reference numbers allows a mechanic or service advisor to quickly verify compatibility with a specific vehicle equipment version, without the risk of selecting an incompatible component.

Condition, benefits of choosing a used part, and installation

As a secondary market part, the caliper is intended for users who want to optimize repair costs while maintaining the original BMW specification. A used brake caliper is a particularly beneficial solution in the case of:

• post-accident repairs,
• servicing high-mileage vehicles,
• restoring a car to factory condition without investing in expensive aftermarket replacements.

Before installation, a standard workshop procedure is recommended: checking for leaks, freedom of piston movement, condition of the guide pins, and replacing the brake fluid in accordance with the vehicle manufacturer's recommendations. A properly prepared caliper allows for restoring stable and predictable braking system operation without the need for interference with other components.

Integration with the BMW braking system

The rear right brake caliper for the BMW G11 is an element of the Brake calipers and carriers category, which means it works directly with the carrier, pads, disc, and brake lines. Thanks to the factory design, the following are maintained:

• dimensional compatibility with the hub and disc,
• correct position relative to safety system sensors,
• adequate body rigidity during intense braking.

A system configured in this way allows for maintaining the braking characteristics intended by BMW for this vehicle generation, which is important for both safety and driving comfort.
