How to fix electric parking brake issues
Today, new vehicles often come with electric parking brakes. That is, the design is seamless and confused. This upgrade seems like a big advance, but there have been many issues with the electric parking brakes that people have to deal with.
If you are not working with this system, read on to learn more about the most common issues with electric parking brakes. It also provides simple fixes that can take care of the problem. There is also a section that will answer your most asked questions in the end. What is an electric parking brake? The electric parking brake (EPB) was first installed on the 2001 BMW 7 Series model. It wasn’t that popular, but it eventually became a new standard for some modern vehicles.
The EPB is active when the driver has a car button. Brake pads are electrically applied to the rear wheel using an actuator motor and an electronic control unit (ECU). This modern system has some positives and drawbacks.

Common issues with electric parking brakes
In most cases, the electrical collector is damaged or damaged. There are also malfunctions of the electric parking brake and cable issues. Low battery voltages can also lead to problems, if the system is not reset or programmed properly. Read these options and see what you need to do.
1. Piston motors can pack or break electric brake calipers
When the electric parking brake was first released, one electric motor was used to pull a standard festival brake cable with a rear brake. However, the confiscated cable still had problems. So, new technology instead applies the brakes to brake the drive engine.
These actuators include a reversible input engine mounted directly on the rear brake caliper. These motors require regular service, but even with proper care, they can get stuck or break. In this case, the brakes cannot be involved or resolved.
2. Electric parking brake malfunction.
To include the electric parking brake, simply press a button on the console. If dirt or debris enters the button, it can stick and fall off. The same applies when you spill a drink on the console and spill liquid on the button.
Sometimes you can clean the buttons to work again. If the situation is severe, you may see a replacement.
3..Cable problems
The parking brake button is connected to the braking system through many wires and connections. Like any other electrical connection, the wires can be damaged and the connection can be damaged. Dirt and debris can cause problems with the connection.
Most of the cables are located in the center console, making inspections easy. However, when dealing with electrical systems, you should always be careful if you don’t know what you’re doing.
4. Low battery voltage
Electric parking brakes require electricity. This was a common problem for people who had to move to start a car. Some vehicles have added a manual release system to override this issue.
5. The system is not reset or programmed properly
Once you have replaced the electric brake block, you will need to reset the system. You must reset the brake caliper using a compatible scanner. If you don’t do this, you may have problems including or solving the parking brake. There may also be a warning light on the dashboard.
How to fix electric parking brake issues
If you are experiencing difficulties with electric parking brakes, there are various ways to repair them yourself. However, I sketch some of the basic fixes, but if you’re not a mechanic, I recommend always bringing your car to a professional.
1. Read the code with a compatible scanner
All modern cars are usually equipped with an OBD II port under the steering wheel near the driver’s door. A compatible scan tool allows you to read all the error codes defined on your computer.
If the brake cord is set, you may be able to decipher it and fix the problem. Our comprehensive trouble code library includes many of the most popular DTCs that explain whether you need more help.
2. Clean/replace the parking switch
If you think the switch is responsible, we’d like to thoroughly clean it up. Try removing clean rags in the row of switches and removing all the debris.
If the switch does not function after cleaning, there may be a problem with wiring, connections, or fuses. Remove the console cover and visually check the entire electronic device. If you notice any definitions or broken things, you should replace them now.
3. Check the engine of the brake caliper
The next step is to inspect the engine of your brake seed Edouter. If you do this yourself, we highly recommend reading your car’s service manual. You should also be able to find some incoming and circuit diagrams for the system that makes it easier to work with.
4. Measure the voltage of the electric brake caliper engine
Before we provide steps to show how it works, we need to inform you that our instructions should not replace manufacturer recommendations. If there is anything else in the service manual, follow these instructions instead. If you don’t have instructions, here are some guidelines.
1. Place the multimeter on the DC (DC).
2. Place the lines on both ends of the main cable tree. 3. Measurements should be minimal and ideally zero.
4. Start the engine and set the parking brake for your friend.
5. If the voltage reads between 10 and 12 volts, the actuator has sufficient output.
6. If there is no voltage or less than 10, you should check the backup or cable.
7. For continuity, you can also test the adjustment of the actuator magnet. Connect the leads and start with a self-test. It should lead to 0 ohms.
8. Once the self-test is working, place the leads on either end of the plug.
9. A beep can cause problems if the actuator winding is good.
10. If it has not been confiscated, replace the actuator engine.
5. Reset the code and learn with the scanner
Whether you have recently changed the back brake or changed the system, you will need to update your system with a compatible scanner. If the brake warning light is on, turn it off using a cord scanner.
An advanced scanner should be able to start the relocation process. If not, upgrade something more professional or move on to the next step.
6. Contact our specialist
No one can expect to understand the advantages and disadvantages of an electric parking brake system. This is a new design and even fights to combat old school professional mechanics. If you feel overwhelmed at any time or don’t have the tools to work, contact your local mechanic for assistance.
To find a reliable mechanic, we recommend reading online reviews. It also helps you to contact your colleagues, family and friends to see who they are using. Before you do your job, ask for a detailed estimate of the parts and shrinkage costs. Can I drive with an electric parking brake problem? If the electric parking brake is busy, you don’t want to drive anywhere. It can damage the rear brake and significantly cut the vehicle.
Once you park, you will no longer be able to apply the brakes. How much does it cost to solve the electric parking brake problem? For example, you can do so at home for a minimal amount of money by simply cleaning up the switch and reducing stickiness. On the other hand, if the drive motor broke down, I could only search for USD 35-500 for parts and labor costs.
Can you manually release an electronic parking brake?
Some vehicles have a setup to manually release the electronic parking brake. If there’s no button, you can also release the parking brake from the rear calipers by getting underneath the vehicle.
If your car has an electric parking brake, you know that it can be a good thing or bad, depending on the day. When everything is working as it should, the brake is easy to use and provides a nice-looking cabin for you to enjoy. However, the second there are problems, you face hours of diagnosis and sometimes a costly repair bill.
If your brake isn’t working right, it’s best to have it repaired right away. With some basic mechanical skills, you should be able to figure out the system on your own. Otherwise, you should have a professional take a look for a quick repair.
