With the caliper off the mount, Leave the old pad in place against the piston. Use a large C clamp and just turn it down until the piston is all the way in. This way you can just pop pads in and out, without having to bleed the brakes. I have been off line for 5 days, so I am just catching up. My Router was down, and I had to wait for a part. It took UPS 5 days to overnight it from ............ NJ. Sheesh. -Staten Island Frank- In a message dated 10/2/2009 9:05:24 P.M.

Also there is a tool, looks like an odd-shaped cube, that is designed to screw the piston back in the caliper. Edit, found it (see 2nd item): http://www.matcotools.com/Catalog/toolcatalog.jsp?cattype=T&cat=2201 That may be what you need, I ran into the same problem on the '95 Gutless. I didn't buy the tool but I ended up figuring a way to screw the piston in... can't recall how though... Take a look at the piston and see if it has indentions for a tool. Chris
