Application and compatibility

The presented set of discs has been designed for the front axle in Mercedes W204 models in AMG versions, taking into account installation on the left and right sides. Basing the construction on Bosch solutions means maintaining the proper operating characteristics of the braking system, in accordance with the vehicle manufacturer's factory specifications.

Thanks to their dedicated purpose for a specific axle and side of the vehicle, the discs ensure proper brake pad guidance, thermal stability, and predictable behavior during intensive braking, which is particularly important in high-performance AMG versions.

Technical and design characteristics

The set includes two brake discs from the Brake discs category, intended for operation on the front axle, with a distinction between the left and right sides. The design is adapted to work with AMG calipers and the Bosch system, which promotes even distribution of braking forces and stable operation across a wide temperature range.

This solution allows for maintaining the appropriate friction surface, predictable wear, and proper cooperation with brake pads intended for AMG versions. The set will perform well both in daily use and in a more dynamic driving style, typical of models with a sporty character.

Condition, verification, and benefits of installation

The items come from the secondary market, which allows for optimizing the costs of braking system maintenance while maintaining the original design specifications. The used set of discs is a good choice for drivers who want to maintain the factory AMG configuration while controlling their service budget.

Properly selected discs for the front axle affect vehicle stability during braking, shorten the braking distance compared to components with improper specifications, and reduce the risk of uneven pad wear. Installing a dedicated set on the left and right side minimizes the risk of vibrations, disc runout, and unwanted noises during system operation.

Installation and operational recommendations

When replacing discs on the front axle, it is recommended to simultaneously check the condition of the pads, calipers, flexible hoses, and hubs to fully utilize the potential of the newly installed set. After installation, it is worth performing a bedding-in procedure, consisting of a series of moderate braking actions, which will allow for even alignment of the friction surfaces and stabilization of the system's operation.
