Purpose and function in the vehicle

The parking brake pedal assembly in the Mercedes ML W164 is responsible for mechanically engaging and releasing the parking brake using the driver's foot pressure. The foot pedal design is characteristic of this generation of Mercedes SUVs and works in conjunction with cables and the drum/disc mechanism in the rear suspension.

The original pedal assembly guarantees:

• proper pedal travel and resistance in accordance with the manufacturer's specifications,
• stable mounting to the body,
• correct operation with the factory brake system and parking brake cables.

Construction and technical features of the pedal assembly

The complete parking brake pedal assembly includes the foot mechanism along with the lever and motion transfer components. This solution ensures precise parking brake operation and consistent performance throughout the entire travel range. The construction is prepared for installation at the factory mounting points in the ML W164 body, which facilitates service and reduces repair time.

As an element from the Pedals, pedal pads, and footrests group, the part has been designed with ergonomics in mind – the pedal position, its angle, and operating characteristics are matched to the driver's position in the SUV cabin, which translates into ease of parking brake operation in daily use.

Benefits of using the original pedal assembly

Using the original parking brake pedal assembly in the Mercedes ML W164 allows for maintaining consistency with the vehicle's factory design. Compared to replacements, the original component ensures:

• precise fit to the body – no need for mounting modifications or adjustments beyond the standard service procedure,
• compliance with the factory brake system geometry,
• predictable behavior when engaging and releasing the parking brake.

Thanks to this, restoring the parking brake's efficiency after replacing the pedal assembly is simpler, and the risk of problems with adjustment or mechanism operation is minimized.

Condition, installation, and service application

The offered parking brake pedal assembly is a used part, which allows for reducing repair costs while maintaining the original manufacturer's specifications. Before installation, it is recommended to perform a standard inspection of the mechanism, check the mounting points, and correctly set and adjust the parking brake cable in accordance with the service procedure for the ML W164.

Replacing the pedal assembly is particularly recommended in the case of:

• mechanical damage to the lever or housing,
• excessive play affecting pedal travel,
• problems with fully engaging or releasing the parking brake resulting from wear of the foot mechanism.
