How should the brake hub fail at high speed? Here are four ways to save the day
In the process of driving on the highway, brake hub failure is a very serious car failure, although the probability of brake failure in daily life is low, but once encountered, if the treatment is not reasonable, it will cause very serious consequences, so it is necessary to master part of the relevant knowledge of braking measures in emergency situations.
Steady direction, turn on double flash: When the brake hub fails in the highway, the first thing you need to do is to steady the direction, let the vehicle continue to slide, and turn on the double flash, so as to prompt other vehicles next to it, first use wind resistance and friction to slow down. The failure of the brake hub is also very likely due to the brief failure of brake fluid or vacuum pump and other components, if in the safe range of the car, you can try to step on the brake pedal frequently, and then wake up the brake system.
Downshift with handbrake: If the brake hub really fails, we can downshift the way to use the engine's braking system, and then let the car achieve the effect of slowing down.
Manual shift model: From the current gear continuously and successively down to the resistance position, then the speed will be reduced, and then the handbrake will brake. Most of today's models are equipped with electronic handbrakes with dynamic emergency braking function. After hanging the low gear, you can directly try to replace the handbrake, the ESP will intervene and hydraulic brake the 4 wheels, which is much safer than the ordinary handbrake.
Automatic transmission model: Hand and automatic transmission as one, so that you can slowly reduce the gear, or use the ground mode to reduce speed.
Use the emergency escape lane: if the handbrake and gear reduction are not good, the driver should sound the siren loudly, mainly to remind the surrounding vehicles to pay attention to the way, and slow down in the appropriate section of road. In many highways will be set up in the downhill section or downhill section of the emergency escape lane, and the lane will have sand and pools, so as to help the vehicle slow down, if the brake hub fails, you can stop through the emergency escape lane.
