Vehicle Application and Placement

The presented brake caliper is designed for installation on the rear left side of the vehicle. Correct placement on the vehicle is crucial for proper brake force distribution and cooperation with other system components.

Thanks to its dedicated application in BMW X5 and X6 models of the E70/E71 generation, the caliper maintains correct mounting points and operating geometry, which facilitates installation and reduces the risk of compatibility issues.

Technical Characteristics of the Caliper

The model designated as 40/20 belongs to the group of calipers used on the rear axle in BMW SUV-class vehicles. Its construction is adapted to work with appropriately selected brake discs and pads, ensuring stable pad guidance and even pressure against the working surface.

This type of brake caliper is a hydraulic component that, after proper bleeding, works with the vehicle's standard brake master cylinder and ABS/DSC system. The correct configuration allows for maintaining factory braking performance and vehicle stability during intense deceleration.

Benefits of Using an Original BMW Caliper

Choosing an original BMW brake caliper from this series is a solution that maintains the integrity of the entire braking system. The most significant advantages of this approach include:

• maintaining the braking system's factory operating characteristics,
• precise fit to the caliper carrier, hub, and brake disc,
• compatibility with standard brake lines and accessories,
• easier diagnostics and future servicing due to the use of a component consistent with factory equipment.

For users who prioritize predictable vehicle behavior, using an original BMW brake caliper offers a sensible compromise between repair cost and operational safety.

Product Condition and Service Application

The offered caliper is in used condition, making it an attractive alternative for budget repairs or restoring vehicle functionality after mechanical damage. Such components are often chosen when the priority is to quickly restore full braking system functionality while maintaining compatibility with factory solutions.

Before installation, standard servicing procedures are recommended, such as checking for leaks, verifying piston operation, potentially replacing seals, and thorough system bleeding after installation. A properly prepared caliper can work seamlessly with new discs and pads, ensuring stable braking performance.

Safe Selection of Used Brake System Components

When choosing a used brake caliper, it's important to pay attention to compatibility with the specific vehicle version, its placement on the vehicle, and the product category.
