1. Understanding Electronic Parking Brake (EPB) Systems

Electronic Parking Brake (EPB) is an advanced system that enhances vehicle safety and convenience. EPB integrates temporary braking during driving and long-term braking after parking. Instead of a traditional handbrake, EPB uses an electronic system controlled by a switch, activating brake pads electronically, usually on the rear wheels.

1.1 EPB System Types: Cable Puller vs. Caliper Integrated

The two primary EPB mechanisms are cable puller systems and caliper integrated systems:

• Cable Puller System: Functions similarly to a traditional handbrake, but an electronic switch replaces the mechanical lever. This system tightens the brake pads on the wheels using a cable and is compatible with both disc and drum brakes. According to a study by the University of Michigan’s Transportation Research Institute in 2022, cable puller systems are cost-effective for vehicle modification due to their high performance-cost ratio.
• Caliper Integrated System: Employs a small electric motor and electromechanical calipers. The motor directly drives the calipers to lock or unlock the parking brakes without cables or levers. While more expensive, this system is highly effective but works exclusively with disc brakes.

2. The Mechanics of EPB Operation

Parking brakes are essential for holding a vehicle temporarily or parking it for extended periods. Traditional systems use a cable connecting the brake pads to a handbrake lever. Lifting the lever increases cable tension, forcing the brake pads to stop the wheels. Modern EPB systems consist of an electronic brake module, an actuator or electric motor, and an electric switch in the cabin.

2.1 How EPB Engages and Disengages

Operating the EPB switch sends a command to the electronic brake module. The module detects the need for parking brakes and instructs the actuators or motors on the calipers to clamp the disc, stopping the wheels. EPB systems are more efficient and reliable due to their advanced electronic components and lack of mechanical connections, enhancing brake reliability.

3. Why Use an Electronic Parking Brake Release Tool?

An electronic parking brake release tool is essential for servicing vehicles with EPB systems. When replacing brake pads, the EPB must be released to allow removal and installation. A diagnostic scan tool sends a command to the EPB system, opening the brake calipers and providing adequate working space.

3.1 The Necessity of Resetting EPB After Maintenance

After replacing brake pads, the scanner orders the motors or actuators to reclamp the brake pads and return them to the working position. Without this tool, servicing EPB-equipped vehicles can be time-consuming and potentially damaging to the system.

4. Key Features of an OBD2 Scanner with EPB Service Mode
