The Tolle sprocketbrake came without a bleeder screw but with 4(!) regular screws. I tried using these to bleed the caliper but that did not work, so I ordered 2 bleeder screw repair kits. These contain both the bleeder screw and the bleeder screw seat. My plan was to install these on the highest points in the caliper, as this is where any trapped air will end up. After disassembling the calipers it turned out that this would not work as there was not enough room. Plan B, we installed one of the bleeder screw kits opposite the brake line connection, and will use a vacuum kit to bleed the caliper...
Also completed the chain guard and heatshrinked the wiring for the handlebar switches.
