How to Solve Insufficient Electronic Parking Force?

Check if there are any issues and perform repairs if necessary. Below is relevant information about the parking brake system: 1. System: The Electronic Parking Brake (EPB: Electrical-Park-Brake) integrates temporary braking during driving with long-term braking after parking, and achieves parking braking through electronic control. The electronic parking brake uses electronic control to achieve parking braking. Its working principle is the same as that of a mechanical handbrake, both relying on the friction generated between the brake disc and brake pads to control parking braking. However, the control method has changed from the traditional mechanical handbrake lever to an electronic button. 2. Advantage: Traditional handbrakes require the driver to manually release the handbrake or skillfully coordinate the throttle and clutch for a smooth start on slopes. In contrast, the AUTOHOLD automatic parking function provides precise parking force through a slope sensor controlled by the system. During startup, the parking control unit calculates information from sensors such as clutch distance, clutch engagement speed, and throttle pedal position.
A few days ago, my car also experienced insufficient electronic parking brake force, and it took some effort to resolve. Common causes include severely worn brake pads leading to inadequate braking force, or faulty electronic sensors misjudging force output. I recommend first trying to restart the vehicle - turn it off and then start it again, as sometimes the system will reset. If that doesn't work, manually check the brake pad thickness; generally, they should be replaced if below 3mm. Also check if the brake fluid level is sufficient, as being too low can affect braking performance. During regular maintenance, remember to have technicians inspect the electronic parking brake system - prevention is key. It's best to visit an authorized dealership or professional repair shop to use diagnostic tools for reading error codes, accurately identifying the issue - safety always comes first.
In the auto repair industry for over a decade, there are two main causes for insufficient electronic parking brake force: first, the brake pads are worn too thin, resulting in insufficient friction; second, faults in the electronic control module, such as signal drift or corrosion. The solution steps are to first use a jack to lift the wheel and inspect the brake pads, replacing them directly if severely worn. Then, use an OBD diagnostic tool to check for system errors, performing a recalibration procedure if necessary. For daily driving, avoid frequent parking on slopes to reduce system load, and regularly change the brake fluid to ensure smooth system operation.
