Where is the handbrake in a Porsche?
1 Answers
Porsche uses an electronic parking brake, which no longer has a handbrake lever but is instead an electronic button. Its position is not in the traditional location of a car's handbrake lever but below the steering wheel, in the same area as the light controls, 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, achieving parking through the friction clamping 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 referred to as 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.
