the Brake Servo uses exhaust manifold pressure to assist the brake pedal, if you try the brakes with the engine off the servo will lose its assistance hence you have to apply more pressure to get the same affect... they rarely go wrong unless there is a leak...

It assist with breaking ( engine running) so you dont have to use as much foot pressure on the brake pedal

Forgive me if I'm wrong but doesn't the servo use the vacuum from the inlet manifold !!!!

cant speak about the Juke but every car i've ever worked on the brake servo is fed from the inlet manifold
