What is the reason for the handbrake malfunction in the Bestune T77?

[McJonathan]

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.

A while ago, my Bestune T77's handbrake malfunctioned—the car wouldn't stay put even on flat ground after engaging it. I consulted a mechanic friend who analyzed that common causes include a broken or aged handbrake cable, insufficient pressure from the brake caliper on the disc, or a failed return spring. In the Bestune model, the design might have multiple connection points prone to jamming. My friend suggested first trying a cable replacement, which cost a few hundred yuan to fix. I believe this also relates to individual driving habits—some people tend to yank the handbrake hard, accelerating wear over time. For safety, it's best to have mechanics test parking force during regular maintenance to prevent accidents.

Handbrake malfunctions are not uncommon in the Bestune T77, often caused by issues with the lever or internal mechanisms. If the car still moves after engaging the handbrake, it could be due to a faulty caliper or spring, or a problem with the hydraulic system affecting the linkage. Last time I encountered this, I immediately stopped to check - the lever wouldn't push down and made creaking noises. I promptly went to the service station to have new components installed. Such problems should be repaired quickly, otherwise there's significant risk when parking on slopes - the vehicle might roll and collide with objects. Normally, avoiding excessive force when pulling the handbrake can extend its lifespan.

Last year, the handbrake of my Bestune T77 suddenly failed—it didn't respond when pulled up, and the warning light didn't illuminate either. After researching, I found that the issue might be due to a short circuit in the sensor's wiring or deformation and jamming of the overall mechanism. This reminded me that rubber components are more prone to problems in high summer temperatures when they soften. I tried adjusting the handle position myself, and sometimes loosening it helped a bit. However, I eventually took it to the shop. The mechanic diagnosed the issue and replaced the cable and spring kit. The whole process took half a day and wasn't too expensive, but it did disrupt my daily use. I recommend that owners pay attention to unusual noises or the flexibility of the handbrake lever—early detection can prevent bigger troubles.
