Vehicle Application and Placement

The presented brake caliper is designed for operation on the front left side of the vehicle. Proper placement on the vehicle is crucial for maintaining the correct braking system geometry, even distribution of braking forces, and proper cooperation with a 305x28 disc. This allows the part to be used as a direct replacement for the factory caliper in selected Mercedes W205 and W213 models.

Construction and Operating Parameters

The caliper is constructed for stable operation with a disc of 305 mm diameter and 28 mm thickness, ensuring adequate friction surface and effective heat dissipation during braking. The design intended for the front axle guarantees:

• appropriate caliper body stiffness,
• correct brake pad guidance,
• efficient transfer of force from the hydraulic system to the disc.

By adhering to the original design specifications, the caliper works with the standard brake master cylinder, lines, and other system components, facilitating installation and subsequent operation.

Service Application and Installation Benefits

Installing a used brake caliper on the front left axle is particularly beneficial in situations where the existing part has suffered mechanical wear, corrosion, or operational damage. Choosing this solution allows you to:

• restore the full functionality of the braking system without altering its design,
• maintain the braking characteristics intended by the vehicle manufacturer,
• reduce repair costs while using an original Mercedes part.

A used caliper can also be used as a component for further refurbishment if the user plans a comprehensive overhaul of the entire braking system in their car.

Fitment, Identification, and Interchange Numbers

This part belongs to the Mercedes brand and has an assigned OEM part number and related interchange numbers, which facilitates unambiguous identification in service catalogs and parts selection systems. This allows for precise verification of the caliper's compatibility with a specific engine and equipment version of the vehicle, minimizing the risk of purchasing an incorrect component. If in doubt, it is advisable to compare the markings with the vehicle's technical documentation or consult a mechanic.

Product Condition and Installation Recommendations

The offered brake caliper is a used part, which means that before installation, it is recommended to thoroughly check it for leaks, piston operation, and guide condition. During installation, it is advisable to:

• use new brake pads matched to the 305x28 disc,
• check the condition of the disc and its working surface,
• bleed the braking system according to the service procedure.

This approach ensures stable, predictable braking and reduces wear on other system components.
