Purpose and compatibility

The presented caliper is dedicated to the rear right side, allowing for precise adjustment to the suspension geometry and braking system of BMW X5 and X6 E70/E71 series. The vehicle placement is factory-defined, ensuring the housing works seamlessly with the appropriate carrier, brake disc, and brake pads, while maintaining the correct position relative to the hub and wheel.

Construction and function of the caliper housing

The brake caliper housing is responsible for the stable guidance of the pistons, even pressure of the pads against the disc, and the transfer of braking forces to the suspension components. In this model, the design has been optimized for weight and rigidity, which promotes consistent braking force and reduces the risk of uneven pad wear.

Thanks to the preservation of the original geometry and mounting points, the installation of the housing is predictable for the mechanic, and the entire braking system can operate within the parameters specified by the vehicle manufacturer. This is particularly important for heavier vehicles, such as the BMW X5 and X6, where the braking system is under heavy load.

Benefits of using an original BMW caliper

Using a factory BMW brake caliper offers a number of practical advantages:

• Secure fit – all original mounting points and the correct spacing are maintained, which facilitates installation and reduces the risk of geometry issues.
• Consistency with other brake components – the housing works with the discs, pads, and carriers specified by the manufacturer, which promotes stable operation of the entire system.
• Professional refurbishment potential – the used housing serves as a good base for caliper renewal, seal replacement, guide pins, and pistons, allowing for optimized service costs.
• Reduced operating costs – choosing an original recycled component is often more cost-effective than purchasing a new aftermarket replacement of uncertain quality.

Condition, verification, and service application

The item is offered as a used BMW brake caliper, which in practice means it has been dismantled and can be used as a part for further operation after appropriate service preparation. Such components are frequently chosen by workshops specializing in the BMW brand, especially for repairs where maintaining the original design of the braking system is crucial.

Before installation, standard workshop procedures are recommended: thorough cleaning, inspection of working surfaces, assessment of threads and mounting points, and – if necessary – replacement of wear-and-tear components included in the complete caliper. A housing prepared in this way can ensure long-lasting and stable operation of the braking system in daily use.

Technical support and part selection

To correctly select the caliper for a specific engine version and equipment level, it is worth using the OEM part number and interchangeable numbers visible in the product technical specification. This facilitates compatibility verification with a specific BMW X5 or X6 unit and minimizes the risk of ordering errors.
