This EPB tool can release a locked electronic parking brake if the vehicle battery is dead or the EPB has malfunctioned. It provides separate left and right caliper channels. Its distinguishing feature is a 1-second automatic shutoff: after the button is pressed, power flows for 1 second and then stops. Additional safety features include a 5A fuse, reverse-polarity protection and a self-test function.
🛑 1-Second Automatic Shutoff Helps Prevent Motor Damage
Pressing the button sends voltage for exactly 1 second before the output is automatically interrupted, even when the button remains held down. This helps stop the EPB motor from overheating and prevents excessive caliper travel. Many inexpensive tools do not include this function.
🔄 Dual Channels for Braking and Release
Two separate channels operate the left and right rear calipers independently. Select Braking Mode to apply the parking brake or Release Mode to disengage it. Both functions are useful when changing brake pads or towing, allowing one tool to handle either task.
⚡ Overload Protection with a 5A Fuse
A replaceable 5A fast-blow fuse is built into the tool. If excessive current is caused by a seized caliper or a short circuit, the fuse opens before damage can occur. Together with the 1-second automatic shutoff, it provides a second layer of protection.
🔋 Reverse-Polarity Protection and Self-Test
If the clips are attached the wrong way around, the circuit will not activate and the tool will not be damaged. Before connecting it to the vehicle, press Self-Test to confirm that it is operating correctly. The DC 10V-14V input is suitable for any standard car battery or jump starter.
📍 Situations Where This Tool Is Useful
Scenario 1: When the battery is below 9V, the EPB will not release. Scenario 2: During rear brake pad replacement, the piston needs to be retracted electrically. Scenario 3: If the EPB control module fails, OBD tools may not communicate with it. Scenario 4: A disabled vehicle can be moved without dragging its tires.

📦 A Practical Tool to Keep in the Glove Box
An EPB can lock unexpectedly, so keeping this tool available helps you handle such a situation when it occurs.
