I own a 1986 Vanagon that I want to do the = front brake pads on . All I have for a manual is a 1983 Haynes . And it shows the = front brake calipers as being Girling or Teves Style .Now I went to check = which one I have and low and behold it is different, from the one they show in the = book.The question is do I have to make the same choice or is it a signal style ?
