Why didn't the electronic handbrake completely replace the traditional mechanical handbrake?

From the working principle, the electronic handbrake and the mechanical hand brake are the same. The mechanical hand brake controls the parking brake through the friction generated by the brake disc and brake pad, while the electronic hand brake is a technology to realize the parking brake through electronic control.

Electronic handbrake has the following advantages:

1. full of science and technology

No matter what advantages we have in use, we are slightly superior in appearance alone. Small and beautiful, with a strong sense of technology. With such parking equipment, the slope is greatly improved and the selling point is also increased.

Save space

Without the long handle of traditional handbrake, the appearance of electronic handbrake saves a lot of space for the storage and operation of central control.

3. Easy to operate

I believe that many drivers and friends have experienced controller braking, which is very laborious. Especially in winter or some cars with long service life, it takes a lot of effort to hold the handbrake. The electronic handbrake only needs to gently lift the switch.

4. Safety

The traditional manipulator brake is usually pulled up after the vehicle stops, so as to prevent the vehicle from slipping when it stops on an inclined road surface and to stabilize the vehicle. Whether the handbrake is tightened or not can only be judged manually. If the cable is loose due to negligence, the consequences will be unimaginable. The electronic handbrake can automatically judge the tightness and has the function of secondary tightening.

Step 5 stand up for the second time

After the vehicle stops for a certain distance, the brake disc will slowly cool down from the high temperature. After cooling, due to a certain degree of contraction of the brake disc, the clamping force of the brake disc will become loose. At this time, the electronic handbrake will automatically clamp again to avoid slipping.

Everything has advantages and disadvantages. Electronic handbrake also has the disadvantages of high cost and poor stability. When the electronic handbrake is abnormal, the maintenance cost is very high. If the situation is not good, the whole electronic module must be replaced. In contrast, the maintenance of the manipulator brake is simpler. When the electronic handbrake fails and the circuit is short-circuited due to external interference, it will not work normally. But the mechanical hand brake is not controlled by electricity, and its stability is much stronger than that of the electronic hand brake.

As for whether the traditional mechanical hand brake will be replaced by electronic hand brake, it should be decided by feedback under the condition of ensuring the driver's safety. We believe that the rapid development of science and technology today will improve all the shortcomings!
