What are the reasons for the brake system failure displayed on BAIC New Energy vehicles?

The reasons for the brake system failure displayed on BAIC New Energy vehicles may be as follows: 1. Severe brake pad wear: Brake pads are divided into two types, with and without sensor lines. Those with sensor lines will automatically connect the circuit when the brake pads wear to the limit position, at which point the fault light will illuminate. If the issue is brake pad wear, the vehicle can still be driven for at least a few hundred kilometers, but it is not recommended to continue driving as worn brake pads can lead to longer braking distances, softer braking, increased noise, and damage to the brake discs. It is best for owners to develop the habit of regularly replacing brake pads, choosing the replacement cycle based on driving habits and road conditions. 2. Low brake fluid level: Brake fluid plays a crucial role in the vehicle's braking system. When the driver presses the brake pedal, the force applied is transmitted by the piston in the master cylinder through the brake fluid to the wheel cylinders at each wheel, causing the brake pads to contact the wheels and stop the vehicle. A lack of brake fluid will also be accompanied by significantly reduced braking force, and in severe cases, a complete loss of braking power. This issue can be resolved by promptly replenishing the brake fluid. 3. Other situations: In addition to the above common faults, there are several other possibilities that may cause the brake system warning light to illuminate, including brake system oil leaks and false alarms. Once the owner notices the brake system warning light while driving, it is necessary to slow down as much as possible, pull over promptly, and then troubleshoot the cause of the fault.
As someone who frequently drives new energy vehicles, I think the brake system fault display might be due to insufficient brake fluid or a leak. Check if the brake fluid reservoir is below the minimum line. It could also be severely worn brake pads; if they're worn down to the metal, it can trigger a warning. A unique aspect of new energy vehicles is the regenerative braking system. If this malfunctions—for example, due to a faulty sensor or an electronic control unit failure—it can also cause a fault display. Loose wiring or a blown fuse are also common causes. In any case, don't ignore it. The brake system is critical for safety, so I recommend getting a comprehensive check at a professional repair shop. You can also check for obvious signs of leakage yourself. Regular maintenance, including changing the brake fluid and inspecting the brake pads, can prevent minor issues from becoming major problems.
I encountered similar issues when driving my BAIC New Energy vehicle, with various possible causes. First, check the brake fluid level and top it up if it's low. Then inspect the brake pads and replace them if they're too thin. Don't overlook the electronic components—faults in wheel speed sensors or ABS modules are common, and loose connectors could also be the culprit. New energy vehicles also have regenerative braking; if it malfunctions, the system might falsely report an error. It's advisable to read the fault codes using an OBD tool for self-diagnosis. Simple issues like tightening connections can be handled yourself, but for more complex problems, visit a repair shop. Remember, safety comes first—brake failure is dangerous, so fixing it early saves both peace of mind and money.
From the perspective of new energy vehicles, brake system fault displays often originate from electronic control issues. For example, abnormal regenerative braking systems, false alarms from sensors leading to error codes, or unstable battery power supply affecting the ECU module. Corroded or short-circuited wiring connectors are also contributing factors. I recommend focusing on checking these electrical components while confirming there are no leaks in the brake hydraulic system. If the fault light comes on after starting, it might be a software bug—try restarting the vehicle's infotainment system. These minor faults can be fixed quickly, so don't worry too much.
