What is the reason for the handbrake malfunction in the Bestune T77?
2 Answers
The causes of the handbrake malfunction in the Bestune T77 include the handbrake not being fully released, insufficient brake fluid, and abnormalities in the braking system. Detailed analysis is as follows: Handbrake not fully released: If the handbrake is released but does not engage the switch properly, the driver should repeatedly confirm whether the handbrake is fully engaged. Insufficient brake fluid: When the brake fluid level falls below the safety line, it can cause the handbrake warning light to stay on, or trigger false alarms. During uphill driving or emergency braking, excessive slopes or fluid turbulence may cause false readings on the fluid level indicator. For such occasional alerts, if the brake fluid is slightly low, adding an appropriate amount of brake fluid can turn off the handbrake warning light. Braking system abnormalities: If the handbrake warning light is on along with the brakes feeling either too soft or too hard, or if the brake pedal returns slowly, it is highly likely that there is an issue with the braking system, and it should be inspected as soon as possible.
I've been driving the Bestune T77 for several years and encountered a handbrake malfunction issue. It's quite annoying as the car still slides slightly when the handbrake is engaged. The main reasons are either a broken or jammed handbrake cable, since I often park on slopes and the repeated usage causes internal springs or steel cables to wear and crack. It could also be due to mechanical failure of the handbrake lever or accumulated grease at the connection point causing adhesion. Later, when I took it to the 4S shop for inspection, the mechanic said low winter temperatures can accelerate component shrinkage and aging. If not repaired promptly, parking on slopes becomes dangerous as the car may slide and potentially cause rear-end collisions. So I addressed it immediately upon noticing the issue. I recommend regularly checking the handbrake lever's tightness and not waiting until major problems arise to fix it.
