Vehicle Application and Placement

The presented brake caliper is designed for the rear left side of the vehicle. It is responsible for evenly pressing the brake pads against the disc, stabilizing braking force on the rear axle and supporting the correct operation of the brake system in the Mercedes W204 class.

Thanks to its precise fit for the specific mounting location, this component helps maintain the correct system geometry, which translates to predictable vehicle behavior during braking, even in emergency situations.

Technical Characteristics of the Caliper

This caliper belongs to the group of components responsible for the mechanical transfer of braking force from the hydraulic system to the disc. The manufacturer's design ensures:

• stable guidance of brake pads on the rear axle,
• adequate rigidity of the caliper body,
• ability to operate within the standard temperature range generated during braking,
• compatibility with the factory brake system architecture of the Mercedes W204.

As an original part, the caliper works with standard brake lines, caliper brackets, and other system components, which reduces the risk of installation issues.

Service Application and Benefits of Choosing a Used Caliper

A used rear left brake caliper for the Mercedes W204 is a practical solution in cases of:

• mechanical damage to the existing caliper (e.g., seized components, corrosion of working parts),
• uneven braking on the rear axle,
• the need to replace a single component without affecting the entire system.

Choosing an original, used component allows you to maintain the factory performance parameters of the brake system while optimizing repair costs. This is particularly important for vehicles where compliance with the original manufacturer's specifications is crucial.

Integration with the Mercedes Brake System

The Mercedes W204 rear left brake caliper has been developed for full compatibility with standard discs, pads, and braking assistance systems. Its proper fit for the W204 platform minimizes the need for additional modifications, and installation involves standard service procedures performed in workshops specializing in the Mercedes brand.
