3. The Force 10 Supertwin TK caliper is a two-piece design setup to fit on both the passenger and driver side of the vehicle. Therefore, there are two bleeder screws and two brake hose inlets. There is an Allen head plug for the lower hole and a new banjo bolt for the brake hose (which will go into the top hole). Six copper washers were given-four thick and two thin. Both thick washers are supposed to go on the banjo bolt, and the thin one is for the Allen head plug. And remember to bleed each side from the bleeder screw that is facing up, not the lower one.
