What to Do If the BMW Handbrake Won't Release?
2 Answers
Check if the handbrake cable is stuck. If the handbrake won't release due to being stuck, try pulling it up harder first, then press the handbrake button and release the handbrake. Inspect the handbrake ratchet mechanism. If this mechanism is damaged, it will prevent the handbrake from releasing. The owner should drive the car to a 4S shop or repair shop for further inspection and repair.
I remember encountering this issue before, where the BMW handbrake wouldn't release is quite common. When I experienced it myself, it was due to the electronic system getting stuck. The electronic parking brake module can sometimes malfunction, such as from unstable battery voltage or sensor errors. It's recommended to first try pressing and releasing the brake pedal multiple times, or restart the vehicle, as this can force a system reset. If that still doesn't work, check if the relevant fuses in the fuse box have blown, located on the left side of the trunk. Don't try to force the car to move, as it can easily damage the brake components. Mechanically, the cable might be rusted and stuck; spraying some lubricant can help. The safest approach is to get it diagnosed at a professional shop as soon as possible—BMW electronic parts are expensive, so don't attempt to disassemble them yourself. Regular maintenance is essential to avoid water exposure and rust.
