How to Use the Handbrake When Automatic Transmission Brakes Fail

Automatic transmission brake failure handbrake method: First release the accelerator pedal, shift the gear to manual mode, and sequentially downshift from high gear to low gear. Some models may prohibit automatic transmission downshifting to protect the gearbox. Each downshift should be coordinated with the handbrake to reduce speed, then continue downshifting sequentially. When pulling the handbrake, press the release button and pull the handbrake continuously without locking it, then press down until the vehicle stops and shift to park. In case of automatic transmission brake failure, immediately turn on the hazard lights to signal other vehicles and avoid traffic accidents, then proceed with gear braking or handbrake braking.
Last time on the highway, I suddenly lost brake response, and the steering wheel was shaking—it really scared me. I remembered my instructor saying not to panic in such situations, to keep the steering steady and downshift first to slow the car down using engine braking. Then, gradually pull up the handbrake—absolutely don’t yank it all at once, as that would cause an immediate spin or rollover. I pulled it up bit by bit, feeling the speed drop slightly before pausing for a few seconds and continuing, like pumping the brakes. The whole time, I kept my eyes locked on the road ahead while frantically honking and flashing hazard lights to warn others. Once the speed dropped to 30-40 km/h, I quickly changed lanes and pulled over, eventually stopping after hitting the guardrail for cushioning. Fellow drivers, it’s best to practice these emergency maneuvers regularly—they can save lives when it counts.
Seeing a friend ask about this, as someone who has worked in a repair shop for over a decade, I must remind everyone that mechanical handbrakes and electronic handbrakes are handled completely differently. For old-style mechanical handbrakes, never pull them abruptly; instead, lift them slowly and intermittently. Once you feel the rear wheels start to drag, pause briefly, allowing for staged deceleration. Electronic handbrakes are simpler—just hold down the P button without releasing it, and the system will control the braking force automatically. Regardless of the type, always combine it with engine braking. For automatic transmission vehicles, immediately shift to L gear or manual mode and downshift continuously. Remember, never pull the handbrake at speeds over 60 km/h, as even a slight deviation in direction can lead to loss of control. It’s best to check the handbrake cable tension every three months.
