TRW Chassis W0133-1625784-TRW Disc Caliper Repair Kit

Perfect fit on the rear caliper of my 1997 Eurovan. Be sure to pull the seal down over the piston, almost off the internal end (away from the pad face), then snap the cylinder side into its groove, all the way around. Next, insert the piston and use a driver/twister tool to push the piston in. (Either rent the tool at auto parts stored or purchase on Amazon - searching for 'Disc Brake Caliper Tool' - buy the full kit) The outer lip will slide up the piston and pop into the groove automatically. If not done this way, you will tear the rubber seal.
