Vehicle Application and Placement

The presented brake disc is designed for operation on the rear axle of the vehicle and can be installed on either the left or right side. This solution facilitates servicing – the component can be used on either side, according to the requirements of a specific car instance. The design is adapted to the characteristics of the braking system used in Mercedes compact class models of the W177 and W247 series, in versions equipped with the AMG package.

Technical and Functional Characteristics

The disc belongs to the Brake Discs category, meaning it is responsible for the crucial stage of converting the vehicle's kinetic energy into heat through cooperation with brake pads. The original design ensures:

• correct cooperation with factory AMG calipers and brake pads,
• an appropriate friction surface, guaranteeing even pad wear,
• stable performance during intensive braking,
• maintenance of the geometry intended by the vehicle manufacturer.

This allows the braking system to maintain predictable effectiveness, and the response to brake pedal application remains consistent with Mercedes' factory assumptions.

Benefits of Using an Original Mercedes Brake Disc

Choosing an original brake disc from the AMG line primarily means guaranteed fit for the specific vehicle platform. The component has been developed for cooperation with safety systems such as ABS and ESP, which is important for vehicle stability in emergency situations. Using a part from the same design family minimizes the risk of vibrations, uneven disc runout, or accelerated pad wear.

The product is sourced from disassembly, which allows for combining the preservation of original specifications with reduced service costs. For many Mercedes users, this is a sensible compromise between quality and budget, especially for comprehensive braking system servicing.

Selection, Installation, and Service Aspects

Before installation, it is recommended to verify the disc's compatibility with the specific engine and equipment version of the vehicle, based on the manufacturer's catalog data or VIN number. Proper installation includes:

• checking the condition of the hub and mating surfaces,
• checking for play in the bearings and suspension components,
• using appropriate tightening torques for mounting bolts,
• proper bedding-in of the disc with the pads after installation.

Service performed in this manner allows for full utilization of the braking system's potential and reduces the risk of undesirable phenomena such as pedal pulsation or noise during braking.
