Vehicle Application and Placement

The presented brake caliper has been designed to operate on the rear right side of Mercedes vehicles from the W166 GLE and C292 series in AMG versions. Its placement on the rear axle on the passenger side is important for the correct routing of brake lines, bleeders, and mounting geometry, therefore this component should be used precisely in its intended position.

As part of the Brake Calipers and Brackets group, this component is responsible for evenly pressing the pads against the disc, stabilizing braking force, and maintaining the correct balance between the front and rear axles. In AMG vehicles, this directly impacts the car's behavior during dynamic driving, emergency braking, and the operation of stability control systems.

Technical and Functional Characteristics

The AMG caliper for GLE / C292 has been constructed as a component that works with the factory Mercedes brake system. This means:

• maintaining original mounting points to the steering knuckle and caliper bracket,
• compatibility with the specified type of brake discs and pads,
• proper piston guidance and even pressure distribution on the friction surface,
• cooperation with vehicle safety systems such as ABS and ESP.

Thanks to its factory specifications, the caliper maintains stable operating characteristics across a wide temperature range, which is important for both everyday use and more intensive driving typical of AMG versions.

Benefits of Using an Original AMG Caliper

Choosing an original Mercedes AMG brake caliper ensures the integrity of the entire braking system. Key benefits include:

• Factory Fitment – no need for modifications to mounts or lines, which simplifies installation and servicing.
• Consistent operation with other braking system components, including the rear disc and pads intended for the specific vehicle configuration.
• Maintenance of the braking characteristics designed by the manufacturer, which is particularly important in higher-powered vehicles.
• Possibility of use in post-accident repairs and when restoring the vehicle to its original AMG factory specification.

An element from this group is a good choice for both replacing a worn caliper and for a comprehensive renovation of the braking system in a GLE or C292.

Condition, Verification, and Selection of a Used Caliper

The offered brake caliper is a used part, which in practice means a favorable compromise between cost and maintaining the original manufacturer's specifications. Before installation, the standard workshop procedure is recommended: checking for leaks, free piston movement, thread condition, and surfaces interacting with the pads and caliper bracket.
