I just bought an 86 GN 56K miles on it. I have been readin this message board for awhile and hear all the horrior stories about powermasters failing. I am actually scared to use the brakes, I try to just coast to stop lights using as little brake as possible. Should I not be that paranoid? Also every time I hit the brakes I hear the pump go on for a bit, Is that ok? Should I just go to vaccum brakes and forget about it?
