EPB Service Tool

AUTOOL BT10 EPB Release Tool

When a vehicle has a system circuit failure, unexpected accident, or battery power loss, the electronic parking brake may lock and fail to release normally. If the repair process relies on forced disassembly or violent reset methods, it may cause motor gear set fracture, deformation of the caliper piston, increase repair cost, and extend maintenance time.

When the electronic handbrake is locked and the vehicle must be moved, using a jack, crane, and tow truck can work, but it is time-consuming and labor-intensive. An EPB release tool provides a cleaner solution: it can release the electronic handbrake during an electronic parking brake malfunction so the vehicle can be moved, tested, or serviced more safely.

Working Principle

How an EPB Release Tool Works

The core working principle of an EPB Release Tool is to bypass the vehicle’s electronic control system and directly provide a controllable power supply to the electronic handbrake actuator motor.

By simulating the release command from the control module, the tool drives the actuator motor in reverse so the parking brake can be released. This helps technicians move the vehicle or service the brake system without forcing the caliper or damaging the motor assembly.

Bypasses ECU Failure

It can operate when the normal electronic control path cannot release the parking brake.

Controls the Actuator Motor

The tool provides controlled power to the electronic handbrake actuator motor.

Simulates Release Command

It reverses the motor action to release the electronic parking brake.

Protects Brake Components

It reduces the need for forced disassembly that may damage gears, pistons, or brake sub-pump components.

Product Recommendation

Why Choose the AUTOOL BT10 EPB Release Tool?

The AUTOOL BT10 is designed for electronic handbrake troubleshooting, workshop maintenance, vehicle movement, and road rescue. It helps technicians release or apply an electronic parking brake quickly when a vehicle cannot respond through its normal control system.

Multiple Application Scenarios

BT10 can be used for electronic handbrake troubleshooting, workshop maintenance, car moving, road rescue, and other service situations.

Dual-Channel Forward and Reverse Control

The dual-channel forward and reverse function allows one-key operation for releasing or braking the electronic handbrake.

Useful for Towing and Repair

When a car needs to be towed after an unexpected accident, or when the brake system is being repaired, BT10 helps release the brake efficiently.

Multi-Circuit Protection

Reverse polarity protection helps prevent equipment damage if the connection is reversed by mistake.

Automatic Self-Test

After power-on, the automatic system self-test and green indicator help show the current working status clearly.

5A Fast-Blow Fuse

The built-in 5A fast-blow fuse can cut off the circuit during over-current conditions to help protect the motor and brake sub-pump.

Usage Scenarios

Where the AUTOOL BT10 Can Help

The AUTOOL BT10 is useful when the electronic parking brake is locked and the vehicle must be moved, diagnosed, or repaired without damaging brake components.

Scenario Problem How BT10 Helps
Electronic handbrake troubleshootingThe EPB locks due to sensor, control module, motor, wiring, or circuit failure.Releases the brake to support maintenance and troubleshooting.
Emergency roadside assistanceThe electronic brake locks after an unexpected accident and the vehicle needs to be moved.Releases the brake so the vehicle can be towed or moved more easily.
4S shop or repair shop vehicle movementThe vehicle locks because of an electronic handbrake power or circuit failure.Helps avoid damage caused by forcibly moving the vehicle.
Brake caliper serviceThe technician needs to service brake calipers or rear brake pads.Releases the brakes to reduce the risk of motor and brake sub-cylinder damage.
Summary
