Purpose and vehicle placement

The presented set includes rear brake calipers mounted on the right and left sides. This solution allows for the simultaneous replacement of both components on the axle, which reduces differences in braking force and helps maintain directional stability during heavy braking. Placement on the rear axle is crucial for the correct distribution of braking forces, especially in cars with a sporty character, where the braking system operates under higher thermal and mechanical loads.

Technical characteristics of the set

The rear caliper set has been designed as an element of the Brake calipers and brackets category, which means it is responsible for the precise guidance of brake pads relative to the disc and the stable transfer of force from the hydraulic system. The design of the calipers is adapted to the specific requirements of AMG models, including the appropriate disc diameter and the characteristics of the friction materials used in these versions. The original origin of the components translates into:

• proper fitment to the mounts on the rear axle beam and steering knuckles,
• pad guidance geometry compliant with factory specifications,
• maintenance of the correct piston working stroke and even pressure on the disc,
• consistent cooperation with the factory ABS/ESP system.

Benefits of using original used calipers

Choosing original, used calipers for a Mercedes allows you to balance cost control while maintaining the performance parameters intended by the manufacturer. Unlike aftermarket replacements with uncertain specifications, factory calipers ensure:

• preservation of factory braking characteristics,
• adequate body rigidity, reducing deflection under high pressure,
• compatibility with stock brake lines, discs, and brake pads. The used set is a good solution when the existing calipers show excessive corrosion, uneven piston operation, or problems with brake pad retraction after braking. Replacing the set on the rear axle allows you to restore the consistency of the system's operation without the need for costly reconstruction of the entire installation.

Professional installation and operation

To fully utilize the potential of the set, installation by an experienced service center is recommended, following procedures for bleeding the system and checking connection tightness. After installation, it is worth paying attention to:

• correct positioning of the pads in the guides,
• even brake pedal travel after bleeding,
• monitoring caliper temperature during the first test drives. After replacing the calipers, it is also advisable to properly bed-in the pads and discs to achieve a stable friction coefficient and avoid local overheating. A braking system prepared in this way ensures a predictable response to the brake pedal and improves safety in daily use as well as during dynamic driving.
