Purpose and fitment

The presented caliper is designed for installation on the front axle on the right side in Mercedes compact class models of the W169 series, compatible with 276x12 discs. The design corresponds to the factory solution used by the manufacturer, which facilitates installation in place of a worn or damaged component without the need for system modifications.

By maintaining the original geometry of the mounts and guides, the caliper allows for correct positioning of the pads relative to the disc, which is crucial for braking efficiency and even wear of the friction linings.

Construction and operating parameters

The brake caliper for the 276x12 disc operates in the front axle disc system, providing appropriate clamping force under typical operating conditions for compact passenger cars. The design provides:

• stable guidance of brake pads in the carrier,
• a piston diameter properly matched for use with the 276x12 disc,
• the possibility of servicing with standard repair kits (seals, guides, dust covers).

This solution allows for maintaining predictable braking characteristics and compatibility with the vehicle's stock hydraulic system.

Practical application and installation

The front right brake caliper for the Mercedes W169 is suitable both for typical replacement of a worn component and for repairs following a collision involving the front suspension. Using this component helps reduce service costs while maintaining the original design of the brake system. Installation is performed in the standard way for front calipers, using factory mounting points on the steering knuckle and the stock brake line.

Before installation, it is recommended to perform standard service procedures, such as checking the condition of the guides and seals, and bleeding the system after assembly to ensure full brake efficiency.

Benefits of using an original caliper

Choosing an original brake caliper for the Mercedes W169 allows you to maintain the consistency of the entire brake system with the manufacturer's design. The most important advantages include:

• factory fitment for the steering knuckle and 276x12 disc,
• predictable operating characteristics in combination with the stock master cylinder and brake force regulator,
• ease of future maintenance in any professional workshop,
• compliance with the vehicle's technical documentation.

This approach is particularly beneficial for users who want to keep their car in a configuration close to the factory state, without experimenting with aftermarket parts of uncertain parameters.
