Purpose and function in the vehicle

The presented brake pedal assembly is designed specifically for the Mercedes ML W164 series SUV equipped with an automatic transmission. The component is responsible for transferring the driver's pressure force to the braking system, maintaining the appropriate travel, resistance, and linearity of operation. The integrated design of the pedal box facilitates installation in factory mounting points and ensures compatibility with other brake system components and vehicle safety systems.

Construction of the brake pedal assembly

The assembly includes a complete brake pedal support unit, i.e., a metal support structure with a pedal arm and guide elements. This type of solution ensures stable mounting to the bulkhead and body, as well as precise pedal movement in a single plane. The design is adapted for use with an automatic transmission, ensuring the brake control system is optimized for the typical usage of a vehicle with such a drivetrain.

Benefits of using the original assembly

Using the original brake pedal assembly in a Mercedes ML W164 allows for maintaining the factory performance parameters of the braking system. Key advantages include:

• maintaining the correct ratio of pedal pressure force to brake system pressure,
• proper cooperation with the brake booster and other system components,
• stable mounting in factory body points,
• consistency with the interior design and driver's area ergonomics.

As a result, the driver receives a predictable, repeatable brake feel, which is important both in daily operation and in emergency situations. The original Mercedes design minimizes the risk of fitment issues that may occur when using replacements with uncertain parameters.

Condition, installation, and service application

The item is offered as a used part, allowing for economical vehicle repair while maintaining the original technical specification. The brake pedal assembly is suitable both for the typical replacement of a worn or damaged module and for post-accident repairs within the front body section and bulkhead. Installation involves removing the old unit and installing the presented assembly in the existing mounting points, following the manufacturer's service procedures.
