[200q20v] sticking caliper

[Kneale Brownson]

You need the Baum 3131 brake caliper tool or its equivalent from one of the 
other makers.  Baum's current price is $25.53.  The 3131 is a plate with a 
square hole in the center for a socket wrench extension bar and it has 
raised bumps on the face designed to fit into the notches in the piston face.
