BMW G01 G20 G21 G30 G31 Brake Disc Set Rear Axle Left Right N/O/S 8853554

BMW G01 G20 G21 G30 G31 Brake Disc Set Rear Axle Left Right is an original set designed for G-series models (including G01, G20, G21, G30, G31), ensuring consistent braking system performance across the entire rear axle. Thanks to their factory origin from BMW, the discs maintain proper operating parameters, and precise fitment to the hub and calipers reduces the risk of vibrations, noise, and uneven wear. This is a solution for users who expect predictable, stable braking while maintaining factory characteristics.

Purpose and fitment for BMW G-series models

The presented set includes BMW rear brake discs mounted on the left and right sides of the axle. The design is prepared for compatibility with the braking system used in modern BMW G-series models, such as mid-size SUVs, premium sedans, or practical estates. Using an original solution allows for maintaining factory braking force parameters, the operating characteristics of assistance systems, and the correct disc geometry in relation to the brake pads.

The placement on the vehicle covers the rear axle on both sides, which enables the simultaneous replacement of the set and the achievement of an even friction surface. This approach is particularly beneficial for vehicles with higher curb weight and dynamic character, where the balance between the left and right sides has a direct impact on stability during braking.

Technical characteristics and role in the braking system

The rear brake disc set in this configuration has been designed as a component that works with factory BMW calipers and pads. The appropriately selected working diameter, thickness, and friction surface ensure:

• consistent transfer of braking force to the rear axle,
• stable heat energy dissipation during intensive braking,
• proper cooperation with safety systems (e.g., ABS, traction control),
• maintenance of predictable brake pedal modulation.

Thanks to their factory origin from BMW, the discs are adapted to the loads typical for modern powertrains and the weight of G-series vehicles. Uniform specifications for the left and right sides facilitate service and minimize the risk of incorrect selection during installation.

Condition, verification, and service application

The offered set is in used condition, making it an attractive cost-effective alternative to new components while maintaining the original BMW design. Such components are particularly often chosen for:

• post-accident rear axle repairs,
• comprehensive braking system renovation in fleet vehicles,
• servicing used cars where a compromise between cost and maintaining factory specifications is key.

Before installation, it is recommended to perform a standard check of the working surface, axial runout, and working thickness in accordance with BMW service documentation. Correctly selected and installed discs allow for restoring braking stability, reducing vibrations, and improving the comfort of the entire system.

Safe selection of used braking system components

In the case of used braking system components, a conscious approach to assessing their condition and compatibility with a specific vehicle version is crucial. It is worth paying attention to the degree of friction surface wear, any signs of overheating, and structural compatibility with your BMW model.

Summary

BMW G01 G20 G21 G30 G31 Brake Disc Set Rear Axle Left Right is a solution intended for users who want to maintain factory braking characteristics in G-series models while optimizing service costs. The original BMW design, fitment to the rear axle, and the possibility of simultaneous replacement of both sides make the set perform well both in routine repairs and during larger service works within the braking system.
