2004 9-3 Aero, 2008 9-3 Aero, 2009 2.0T XWD
My 08 wouldn't even buzz and the brake pedal was always hard at start up. I pulled a pump from a yard and now the problem is sorted. I have since pulled 4 or 5 more of these. I took my old one apart and it's just a cup with two magnets and coiled wire that spins a plate with little square like pieces in order to generate a vacuum. What actually falls on these? Surely they can be refurbished?
