Purpose and Fitment

The presented caliper is specifically designed for installation on the rear right side of W204 series models. Correct placement on the vehicle guarantees proper pad guidance on the disc, stable piston operation, and even distribution of braking force on the rear axle.

By retaining the original geometry of the mounts and guides, the caliper works with the factory-specified disc and pads for this axle, facilitating installation and reducing the risk of improper component fit.

Construction and Technical Characteristics

The caliper is part of the group of components responsible for mechanically transferring hydraulic pressure to the brake pad. The body, guides, and piston housing are constructed to ensure stable operation under typical operating conditions for Mercedes W204 class vehicles.

Key structural features of this caliper include:

• dedicated mounting for the rear right knuckle,
• compatibility with the factory brake hose,
• maintenance of the original braking force characteristics on the rear axle.

This solution allows for maintaining the integrity of the entire braking system without the need to modify other components.

Benefits of Using an Original Mercedes Caliper

Choosing a used, original caliper for the Mercedes W204 is a sensible compromise between cost and quality. A part from the same product line as the factory-fitted one ensures:

• compliance with the manufacturer's design specifications – proper fitment to the hub, disc, and pads,
• consistency with the factory braking system,
• maintenance of the manufacturer-specified braking characteristics for the rear axle.

This allows the driver to maintain predictable vehicle behavior during braking, and simplifies diagnostics and system maintenance for the service center.

Professional Installation and Operation

The brake caliper is a safety component, therefore installation by a qualified workshop is recommended. During installation, attention should be paid to:

• proper bleeding of the braking system,
• checking the condition of the disc and pads on the rear right axle,
• verifying the smooth operation of the guides and piston movement.

After installation, a test drive is advisable to verify even braking and confirm the caliper's correct interaction with other system components.
