What is the reason for the brake failure of the Benben E-Star?

The reason for the brake failure of the Benben E-Star is the occurrence of batch-related issues with the brake vacuum booster pump, which causes the brake pedal to become stiff during driving, leading to a decrease in braking effectiveness and creating a sensation of brake failure. There are three types of brake systems as follows: Foot Brake: The commonly used brake while driving is operated by the foot, hence also known as the foot brake. When the driver presses the brake pedal, the braking force is transmitted mechanically or hydraulically to the wheel's braking device to generate friction. Parking Brake: Also known as the hand brake, it is a braking device used to prevent the vehicle from sliding when parked. Generally, there are two types: the intermediate brake installed on the drive shaft and the direct control rear wheel brake. Anti-lock Braking System (ABS): When driving on slippery or icy low-friction roads, excessive braking can occur, causing the wheels to lock up and lose traction, leading to a loss of directional control. To enable effective control of the vehicle's direction on such hazardous roads, the anti-lock braking system was developed.
The most common issue causing brake failure in the BenBen E-Star is insufficient hydraulic pressure in the braking system, such as brake fluid leakage or low levels, leading to reduced pump pressure and weakened braking force. Excessive wear on the brake pads can also significantly diminish braking effectiveness, especially after frequent hard braking, as material fatigue accelerates failure. As an electric vehicle, the BenBen's electronic power assist system can sometimes malfunction, such as ABS module failure or sensor data misreporting, which may trigger unexpected issues after software updates. I've also noticed that damp environments can corrode wire connectors, affecting overall performance. It is recommended that owners check fluid levels and system circuits every six months to mitigate risks.
I've experienced brake failure, and most issues with the BenBen E-Star stem from long-term maintenance neglect. If the brake discs warp or rust, they can cause vibrations at high speeds, reducing efficiency. A leaking booster pump makes the pedal feel soft and weak, possibly due to aged fluid or cracked lines. Especially in cold weather, the fluid thickens, affecting responsiveness. Don't overlook basic maintenance like changing brake fluid and cleaning dust, as this can prevent most problems. Driving habits also matter—avoid lugging or emergency braking to prevent overheating parts. For safety, it's best to have a professional shop inspect the system.
