Purpose and vehicle placement

The presented brake caliper is designed for operation on the rear right side of the vehicle. It is responsible for generating the clamping force of the pads against the disc, stabilizing the braking efficiency of the rear axle, and supporting an even distribution of forces throughout the entire braking system.

The placement on the vehicle is precisely defined, which facilitates the selection of parts during repair or replacement of braking system components in Mercedes E-Class models and related vehicles based on the W213 and C238 platforms.

Technical and functional characteristics

As an element from the Brake calipers and carriers category, this caliper works with the vehicle's factory hydraulic system, ensuring proper piston travel, stable pad guidance, and effective heat dissipation from the disc area. The design provided by the manufacturer allows for the maintenance of standard braking parameters without the need to modify other system components.

The used nature of the part means it is a service solution that allows for economical repair while maintaining the original mounting geometry and compatibility with factory brake lines and mounting hardware.

Benefits of using an original caliper

• Factory fitment – preservation of original mounting points and compatibility with other braking system components.
• Rear axle consistency – proper operation of the caliper on the rear right side supports vehicle stability during braking.
• Service solution – the used component allows for restoring system efficiency without the need for costly reconstruction.

For workshops and individual users, this means the possibility of performing repairs based on a part consistent with the vehicle manufacturer's original design assumptions.

Selection and operational safety

When selecting a used brake caliper, it is crucial to verify compatibility with the specific body version and braking system. Proper fitment of the rear right component to a given Mercedes model affects even pad wear, stable disc guidance, and correct interaction with braking assistance systems.
