Installing the tongs that are operated by the hand brake may prove to
be problematic. The link to the chain must be balanced on top of the
tong and held there while the end of the cylinder is slipped in. I
don't know how you'd do this without four hands, or a special pin to
hold them in place while the cylinder is wrestled into position. Since
none of us are going to grow a fourth hand, two of these pins can be
made from a piece of black iron pipe and a couple of washers. Cut them
short enough not to interfere with insertion of the cylinder but long
enough to hold the link in place atop the tongs.

When tightening up the castellted nut on the ends of disc brake tong
pins, the pin is apt to rotate and prevent you from turning the nut
against the thread friction caused by the spring pressure. This special
purpose pin wrench allows the tong pin to be held in place as the nut is
tightened. A simple tool makes the job so much easier.
