Is there a special tool to use with the rear wheel cylinder bleeders? A standard 5/16 brake bleeder wrench is too fat to fit into the well that the bleeder sits in. No parts stores had any ideas aside from getting longer bleeders that protrude from this "well.". I ended up taking a deep well 5/16 socket and fed aquarium tubing through it to attach to the nipple. I turn the bleeder open and closed with vise grips around the socket. There has to be a tool or a better way to do this. I am doing the traditional pump and hold with the tubing going into a bottle of fluid.
