Are the a/c and the vacuum system related? Maybe because of the increased power the engine needs no turn the a/c compressor?
thanks

1994 GTi 2.0. 100k miles. When the A/C is turned on, the car requires more "foot effort" to brake. I can be pressing he brake pedal and if I turn the A/C off, the pedal goes a little bit inwards, because of the lower effort required. The A/C has recieved maintenance. I thnik it must be something vacuum related. The A/C compressor does have a lot of internal resistence, the car gets noticeably slower, with no low end torque at all (far below normal).
