Purpose and technical fitment

The presented caliper is structurally designed for operation on the front right side of the vehicle, in a system compatible with a brake disc with a diameter of 295 mm and a thickness of 28 mm. This configuration ensures an adequate friction surface, thermal stability, and predictable behavior during intensive braking, which is important both in daily use and during dynamic driving.

Its original origin from the Mercedes range promotes the maintenance of the correct operating characteristics of the braking system – from the pad clamping force and even pressure distribution on the disc, to compatibility with factory lines and mounts. As a result, the caliper can be used as a replacement part without the need for modifying the steering knuckle structure or mounting brackets.

Construction and function in the braking system

The brake caliper is responsible for converting hydraulic pressure into the clamping force of the pads against the disc. This model uses a solution typical for modern disc systems, ensuring:

• stable pad guidance in the carrier,
• even pressure against the working surface of the disc,
• adequate body rigidity to limit deformation under load,
• serviceability with standard repair kits (seals, guide pins, boots).

Selecting a caliper with the correct specification (disc diameter and thickness, vehicle placement) is crucial for maintaining balanced braking forces between the sides of the vehicle and for proper cooperation with the ABS and electronic stability control systems.

Benefits of using an original used caliper

Using a used, original caliper for a Mercedes allows for reduced repair costs while maintaining the high manufacturing quality characteristic of the manufacturer. Compared to low-budget replacements, the factory caliper offers:

• precise fit to the hub and steering knuckle,
• compliance with factory braking system parameters,
• the possibility of future regeneration and servicing,
• consistency with other system components (discs, pads, lines).

This solution is particularly beneficial for repairs of vehicles used intensively, where both safety and rational maintenance costs are important.

Installation and maintenance recommendations

When replacing the front right caliper in a Mercedes, it is recommended to simultaneously check the condition of the disc, pads, flexible lines, and brake fluid. Proper installation includes:

• thorough cleaning of the contact surface between the caliper and the steering knuckle,
• checking the guide pin clearance and applying appropriate lubrication,
• bleeding the brake system after connecting the line,
• verifying braking uniformity at a diagnostic station.

Performing the procedure in this manner allows you to fully utilize the potential offered by the Mercedes W204 Brake Caliper Front Right O/S Wheel Brake TRW 295X28 and reduces the risk of uneven braking or disc overheating.

If you are planning a comprehensive repair or upgrade of the braking zone in your Mercedes and need other components from the same group, such as additional calipers, carriers, or mounting brackets, check the available parts in the Mercedes Brake Calipers and Brackets category.

For users considering the purchase of a used caliper, a guide describing how to safely select brake system components from the secondary market – from visual assessment and leak verification to selection based on vehicle specifications – will be particularly helpful. Practical tips can be found in the article "Second-hand braking system: how to safely choose discs, calipers, and ABS?", which will facilitate making an informed purchasing decision.
