> I assume that you're speaking of a brake cable splitter. The brake cables of the length necessary for a tandem are a problem. They are normally too long for the distance from the front brake lever to the middle where the splitter is. This means that you have to cut the cable to fit thereby losing the soldered and secure end. Spliters also usually have too much room in them and hence tightening the cable end allows the end to flatten out and slip through the rounded off end of the screw tightening the front cable into the splitter. I seem to remember that the way that I solved the problem was with an S & S clitter/coupler which was designed better for the problem.

Tandems and travel bikes use splitters for gear wires only, 
not brake wires.
