Noticed the other day, if I go from full boost onto the brakes I get little assistance initially! Checked the vac line off of the pump to the servo and sure as anything both ends cracked, the vac pump end I could actually pull the rigid pipe off of its connector! So for a temp fix I’ve used some pretty tough tape and ties to seal the pipes and now I have assistance as soon as I come off the throttle in boost and the pedal overall feels more responsive! I have always had a very slight hiss from the pedal area and assumed I have a small leak on the servo, but now I’m thinking the lines are letting air being pulled into the servo under vacuum thus causing a slight audible hiss?
