Nissan Qashqai 2024 Owners Manual
7.37.1.1. Vacuum assisted brake
The brake booster aids braking by using engine vacuum or vacuum from an engine-driven pump. If the engine stops or the drive belt is broken, you can stop the vehicle by depressing the brake pedal. However, greater foot pressure on the brake pedal will be required to stop the vehicle and the stopping distance will be longer.
