Purpose and vehicle placement

The presented caliper is designed as a braking system component mounted on the rear right side of the vehicle. It is responsible for evenly pressing the brake pads against the disc, which translates into stable rear axle braking and proper distribution of braking forces in the Mercedes S-Class W220 generation.

The dedicated placement reduces the risk of issues with system geometry, leaks, or uneven pad wear that may occur when using mismatched replacements.

Construction and technical parameters in practice

As an item from the Brake calipers and brackets category, this model utilizes factory Mercedes solutions, ensuring appropriate body rigidity, correct piston travel, and compatibility with the brake line and steering knuckle mount. The construction is prepared for operation in the standard hydraulic system used in the W220, which facilitates integration with the existing installation.

An original caliper of this type is designed for:

• stable pad pressure across the full range of operating temperatures,
• proper heat dissipation from the area around the disc,
• maintaining the correct position relative to the brake disc,
• proper cooperation with the factory brake control system.

Condition, selection, and service application

The item is offered as a used Mercedes brake caliper, which allows for economical repair of the braking system while maintaining the manufacturer's original specifications. This type of part will work well both when replacing a damaged caliper and during repairs following guide pin corrosion, piston seizure, or uneven pad wear on one side of the axle.

Before installation, standard service procedures are recommended: checking for leaks, the condition of working surfaces, threads, and mating mounting elements. A correctly selected and prepared caliper helps restore predictable, repeatable braking and reduces the risk of the vehicle pulling during emergency braking.

Safe selection of used braking system components

When choosing a used caliper, it is worth paying attention to compatibility with the braking system of a specific W220 version, the condition of the body, and the completeness of connections. Detailed tips on how to verify such components can be found in the guide: Second-hand braking system: how to safely select discs, calipers, and ABS?, where practical criteria for evaluating used components in a store specializing in car parts are described.
