Hi all,
     
     I am trying to replace the front brake pads on my 87 Vanagon 
     Westfalia.
     
     Bentley says that once the old ones are replaced, "push" the piston 
     back into the caliper housing so it will have enough clearance to fit 
     back down over the pads.  The diagram shows a tool of some sort which 
     is used to accomplish this.  Of course, I don't seem to be able to 
     push it in by hand.
     
     What is the best method for resetting the piston when replacing the 
     front brake pads?  Is there a FAQ file or a web site somewhere that 
     explains this process?
     
     I tried searching the archives, but found wading through thousands of 
     unrelated and incomplete threads too tedious.  I also could not find a 
     FAQ section on the subject, though I'm sure there must be one 
     somewhere.
     
     Thank you in advance for any help you can give......
