Passat 2003 tdi, brake pad change..

Proper size wrenches and a large C-clamp to push piston back into the caliper is only tools for the front, but back disk brakes require special tool to TURN the piston as it is pushed back into caliper to reset emergency brake. This tool can often be borrowed from Auto parts store or purchased from Harbor Freight http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=40732 for about $20. Don't try to service rear disks without the tool, Calipers can be broken if not retracted properly!
