Vehicle Application and Fitment

The presented caliper belongs to the Brake Calipers and Brackets group and is designed for operation on the rear axle, left side of Mercedes W205 and X253 vehicles with AMG systems. Its placement on the driver's side of the vehicle allows for maintaining the correct brake system geometry and compatibility with the factory-specified discs, pads, and brake lines for this configuration.

Original origin from the Mercedes brand means that correct mounting points, appropriate spacing, and guide geometry are maintained, facilitating installation in place of a worn or damaged caliper without the need for modifications to other system components.

Technical and Functional Characteristics

The caliper operates within the AMG braking system, where precise pad guidance and stable disc pressure under repetitive thermal loads are crucial. The design intended for installation on the rear axle, left side, ensures:

• correct positioning relative to the brake disc,
• proper cooperation with the factory brake hydraulics system,
• maintenance of the manufacturer-specified braking force characteristics between the front and rear axles.

As an original component, the caliper complies with factory requirements regarding body rigidity, piston operation, and resistance to operational loads typical for Mercedes W205 and X253 models with the AMG package.

Condition, Origin, and Service Application

This part comes from the secondary market and is offered as a used brake caliper, allowing for economical brake system repair while maintaining the original manufacturer's specifications. This type of solution is particularly beneficial for:

• post-accident repairs, where the replacement of a single caliper is necessary,
• fleet vehicle servicing, where cost optimization is key,
• maintaining consistency with the factory AMG system without resorting to aftermarket parts with uncertain parameters.

Benefits of Using an Original AMG Caliper

Choosing this caliper for a Mercedes W205 or X253 with an AMG system allows for the preservation of factory braking characteristics and predictable vehicle behavior during intense braking. The original design supports:

• stable pad guidance within the caliper,
• even wear of friction components,
• proper cooperation with vehicle safety systems such as ABS or ESP.

For workshops and individual users, this means a lower risk of fitment issues and the ability to efficiently restore full brake system functionality in AMG-equipped vehicles.
