What kind of brake is the parking brake?
Explanation
Correct answer: Passive - operates even after switching off the tram.
The parking brake is a passive brake, which means that it does not require energy to be applied; on the contrary, a lack of energy engages it. Its operation is based on mechanical force (e.g., springs), which is released in the absence of pressure in the braking system. Therefore, it is effective even after the engine has been switched off or in the event of a power failure, ensuring the vehicle is safely immobilised.
