Intended Use and Vehicle Placement

The presented caliper is designed to operate on the front right side of the braking system. This means its geometry, mounting points, and pad guides are adapted to its specific working position in the suspension, minimizing the risk of installation issues and ensuring proper interaction with a 295x28 disc.

The vehicle placement is clearly defined in the technical specifications, allowing a mechanic or user to precisely verify compatibility with their Mercedes model from the W176 or W246 series.

Caliper Construction and Function in the Braking System

The brake caliper is responsible for converting hydraulic pressure into clamping force on the brake disc, so its construction must ensure adequate body rigidity, smooth pad guidance, and stable piston operation. This model features solutions typical for factory Mercedes calipers, promoting even pad wear and consistent braking force.

In practice, this means:

• secure pad guidance within the bracket, limiting sticking,
• appropriately sized pistons, facilitating proper pedal travel,
• compatibility with the manufacturer-specified disc with a diameter of 295 mm and a thickness of 28 mm.

Benefits of Using an Original, Used Brake Caliper

Choosing an original, used brake caliper for a Mercedes allows for cost control while maintaining factory operating parameters of the system. This type of component is designed for a specific vehicle platform, ensuring:

• compatibility with the factory braking system and suspension geometry,
• reduced risk of installation problems due to dimensional differences,
• maintained predictable vehicle behavior during emergency braking.

The used condition indicates that the part has been previously in use but can still perform its function after proper installation and verification by a mechanic. This solution is often chosen for post-accident repairs or when replacing a unilaterally damaged caliper.

Vehicle Fitment and Installation Aspects

To fully utilize the potential of this caliper, correct fitment to the specific Mercedes version and adherence to the manufacturer's installation procedures are crucial. Pay attention to:

• matching the installation side (front, right) with the vehicle's current configuration,
• selecting pads and discs with appropriate working dimensions,
• checking the condition of brake lines and bleeding the system after installation.

When selecting parts, the available OEM part numbers and interchange numbers in the specifications are helpful for verifying compatibility with specific body variants and engines.
