Where is the Porsche handbrake?
1 Answers
Porsche uses an electronic parking brake, which no longer has a handbrake lever but is an electronic button. Its location is not in the traditional handbrake lever position of conventional cars. Instead, it is positioned below the steering wheel, in the same area as the light controls, and marked with a 'P' symbol. More details are as follows: 1. The working principle of the electronic parking system is the same as that of the manual mechanical parking brake system. It achieves parking by clamping the friction between the brake shoes and the brake drum or between the friction pads and the brake disc. However, the control method is replaced by electronic buttons and motor actions instead of the original manual operation and mechanical linkage. Therefore, the system is fully called the electronically controlled mechanical parking brake system. 2. Currently, there are two main forms of electronic parking brake technology applied in cars: one is the cable-type electronic parking brake system, and the other is the caliper-integrated electronic parking brake system. 3. The cable-type electronic parking brake system retains the cable of the traditional mechanical parking brake system. The motor components are integrated into the left and right rear brake calipers, and the electronic control unit (ECU) and motor components are directly connected via electrical wiring harnesses.
