In recent years, the Electronic Parking Brake is exceedingly common in the vehicles. EPB is a smarter, safer and more convenient means of braking the wheels under a variety of situations.
1. What is Electronic Parking Brake (EPB)?
Electronic Parking Brake (EPB) is an advanced technology that provides temporary and long-term braking on vehicles. This system can be easily activated by the driver through an electronic switch, which applies brake pads to the wheels, usually the rear wheels, with the help of the Electronic Control Unit (ECU) and actuator mechanism. Currently, there are two types of EPB mechanisms available: cable puller and caliper integrated systems.
Cable puller systems work similarly to a traditional handbrake, but the mechanical lever is replaced with an electronic switch. This type of system is suitable for both disc and drum brakes, making it a cost-effective option for vehicle modification.
Caliper integrated systems, on the other hand, use an electric motor and electromagnetic calipers to lock/unlock the parking brakes without any cable or handbrake lever. However, this system is only compatible with disc brakes and is relatively more expensive.
2. How does EPB Work?
EPB, or Electronic Parking Brake, is a system that allows a driver to engage the parking brake with the push of a button rather than pulling on a lever or pedal. The EPB system consists of three main components: the electronic brake control module, the electric motor, and the actuator.
When the driver activates the EPB switch, a signal is sent to the electronic brake control module, which then activates the electric motor. The electric motor engages the actuator, which in turn applies pressure to the brake pads, causing them to clamp down on the brake rotor or drum. This creates friction and prevents the wheels from turning, effectively engaging the parking brake.
The EPB system offers several advantages over traditional parking brake systems, including increased safety, convenience, and reliability. Additionally, the lack of a mechanical connection between the brake lever and the brakes themselves means that the system is less prone to wear and tear and requires less maintenance over time.
3. Why do You Need the Electronic Parking Brake Release Tool?
The Car Diagnostic Tool with Electronic Parking Brake Release Function is several reasons why you might need this tool:
Emergency situations: If your vehicle’s electronic parking brake system fails, or the battery dies, you may need to release the parking brake manually using the diagnostic tool.
Brake maintenance: When performing maintenance on the rear brakes, such as replacing brake pads or rotors, the electronic parking brake system needs to be disengaged first. Using the UDIAG diagnostic tool can make this process easier and more efficient.
Wheel/tire changes: If you need to remove or replace a wheel/tire on a vehicle equipped with an electronic parking brake system, you will need to release the parking brake using the tool with EPB release function before doing so.
It’s important to note that not all vehicles with electronic parking brakes require the use of a release tool. Some models may have a manual release lever located inside the vehicle or on the brake caliper itself. Please contact UDIAG’s professional technicians for guidance on how to properly release the electronic parking brake.
