Audi A4 B8 Brake Pedal Assembly Box 8K2723140

Audi A4 B8 Brake Pedal Assembly Box is an original brake control system component, designed for precise operation with the vehicle's factory brake booster and hydraulics. As part of the Pedals, pedal pads and footrests group, it ensures proper transmission of the driver's pressure force to the braking system and provides stable mounting within the pedal box. This solution is dedicated to Audi, allowing for the preservation of factory brake performance characteristics and interior structural consistency.

Purpose and function in the braking system

The brake pedal assembly in the Audi A4 B8 is responsible for the mechanical transmission of force from the driver's foot to the master brake cylinder via the lever and linkage. The design is optimized for:

• appropriate force transmission to achieve predictable brake response,
• controlled pedal travel, facilitating the modulation of braking force,
• stable pedal guidance along the operating axis, without unwanted lateral play.

The original brake pedal assembly maintains factory mounting points in the body and correct geometry relative to other pedals, which translates into a comfortable and repeatable foot position for the driver.

Construction of the brake pedal assembly

The complete brake pedal box includes a load-bearing structure mounted to the firewall and a pedal arm that works with the brake booster. The lever geometry used ensures:

• a smooth start of travel, facilitating gentle deceleration,
• a more decisive response in the latter part of the travel, needed for emergency braking,
• consistency of pedal feel with the factory ABS/ESP system.

Thanks to the preservation of the original design, the brake pedal assembly works with factory mounting points for covers and upholstery, which facilitates installation and subsequent service.

Benefits of using the original brake pedal assembly

Using an original component from the Pedals, pedal pads and footrests group in an Audi brings a number of practical technical benefits:

• preservation of factory brake pedal operating characteristics,
• secure fit to the firewall and brake booster,
• no need for mounting modifications or interference with the body structure,
• consistency with other control system elements (clutch pedal, accelerator pedal).

This solution is particularly recommended for post-accident repairs, replacing worn pedal mechanism components, or restoring full functionality of the braking system after long-term use.

Condition, verification, and installation

The item is offered as a used part, which in practice means maintaining original manufacturing quality at a more favorable cost compared to a new replacement. Before installation, a standard inspection of the mechanism for smooth movement, operating play, and correct return spring operation is recommended.

Replacing the brake pedal assembly requires removing the lower part of the covers under the steering wheel and accessing the firewall from the cabin side. Thanks to factory mounting points, installation is predictable, and after properly tightening the bolts and connecting the linkage to the brake booster, the system is ready for bleeding and road testing.

Expanding the Audi brake control system

If you are planning a comprehensive repair or upgrade of the braking zone in your Audi and need other elements from the same group, such as additional pedals, pedal pads, or driver footrests, check the available parts in the Audi Pedals, pedal pads and footrests category.

When planning broader service work, it is also worth paying attention to the selection of original used components in other vehicle systems.
