Purpose and vehicle placement

The presented brake caliper is designed to operate on the rear right side of the vehicle. It is responsible for evenly pressing the pads against the disc, stabilizing the braking force on the rear axle and supporting the vehicle's safety systems. The dedicated placement minimizes the risk of installation issues and ensures proper pad guidance and correct positioning relative to the disc.

Technical and design characteristics

The caliper belongs to the Brake calipers and carriers group, which means it has been designed as a load-bearing and working element of the braking system. The design is intended to work with the factory Mercedes braking system, maintaining the appropriate mounting points, piston guidance, and brake fluid flow channels. The red paint serves both a protective and visual function, improving the surface's resistance to external factors and emphasizing the vehicle's sporty character.

Benefits of using an original Mercedes caliper

Using an original caliper in the Mercedes W204 model allows for maintaining the structural integrity of the entire braking system. Key advantages include:

• maintaining factory mounting geometry and pad operation relative to the disc,
• proper fitment for brake lines and associated components,
• consistency with rear axle operating parameters, which promotes vehicle stability during braking,
• aesthetic red finish improving the appearance of the wheel area.

As a result, this component can be used both for standard replacement of a worn caliper and for visually refreshing the braking system.

Product condition and practical application

The offered caliper is used, which in practice means it comes from disassembly and can be an economical alternative to a new component. This type of solution is often chosen for maintenance repairs when the priority is to maintain the original system design while optimizing costs. Before installation, standard verification of the component in a workshop is recommended, in accordance with service procedures for the braking system.
