Mercedes W205 W213 Front Brake Caliper Housing Right O/S 305x28mm A2054210281

Mercedes W205 W213 Front Brake Caliper Housing Right O/S 305x28mm is an original braking system component from the Brake calipers and brackets category, designed for installation on the front right axle. This used, factory-spec caliper ensures a proper fit for the hub and a brake disc with a diameter of 305 mm and a thickness of 28 mm, resulting in stable braking performance and predictable vehicle behavior. This is the ideal solution for users seeking a proven OEM part rather than cheaper, unknown-origin replacements.

Purpose and technical fitment

The presented caliper is designed for use on the front right side of the vehicle, in a system compatible with 305x28 mm brake discs. This configuration is characteristic of many versions of the Mercedes C-Class (W205) and E-Class (W213) models, where maintaining the correct friction surface and braking system rigidity is essential.

The factory design of the caliper guarantees:

• correct positioning relative to the brake disc,
• adequate brake pad clamping force,
• compatibility with the stock master cylinder and ABS/ESP system,
• retention of the factory brake pedal feel and performance.

Benefits of using an original Mercedes caliper

Choosing an original brake caliper for your Mercedes primarily ensures dimensional and material compliance. A component from the same product line as the factory-installed part helps avoid issues with uneven pad wear, disc overheating, or improper piston operation.

Key advantages include:

• retention of factory braking efficiency parameters,
• stable operation at high temperatures typical of intensive braking,
• properly matched guide and pad seat geometry,
• easier diagnostics and maintenance due to compliance with manufacturer documentation.

As a result, the Mercedes braking system maintains its predictability and operational comfort, which is significant for both daily driving and dynamic highway travel.

Characteristics of the used caliper

The offered item is in used condition, allowing you to combine original manufacturing quality with an attractive price compared to new parts. This type of solution is particularly beneficial for repairs where both safety and service cost optimization are priorities.

A used Mercedes brake caliper, when installed correctly and used with appropriate pads and discs, can still provide:

• even distribution of braking forces on the front axle,
• proper piston retraction after releasing the pedal,
• stable pad guidance within the bracket,
• continued serviceability (cleaning, seal replacement, guide lubrication).

Application in the Mercedes W205 / W213 braking system

In Mercedes W205 and W213 models, the braking system is designed with a high safety margin, which is why it is crucial to use components with the correct specifications. The front right brake caliper 305x28 mm works with a disc of a specific diameter and thickness, which affects heat dissipation efficiency and fade resistance.

When replacing the caliper, it is worth paying attention to:

• the condition of the brake disc (no excessive wear or runout),
• the selection of brake pads with the appropriate friction coefficient,
• the tightness of the brake line and proper system bleeding,
• the cleanliness of the mounting surfaces on the steering knuckle and bracket.
