SideCar Brake Help
Hello Everyone,
Ok I am going to give you a quick run down of what I have going on. I bought a Motorvation sidecar and have finally gotten around to bolting it to my 2004 Fatboy. The problem I have run into is the brakes. This system requires me to Tee it into my rear brake on the bike. I have done that but cannot for the life of me get a firm pedal at all. I have bleed many of brakes on all kinds of things and cannot get this handled. I am now thinking it might be the master cylinder size. I am not sure how many pistons my fatty has in the rear caliper since i am to lazy to take it off but i know the side car has 4 pistons and the line going over is 80"+. I think i have narrowed this down to the master size being to small to move all of these pistons? Am I on the right track? Would a touring model master work. I don't need anything aftermarket and chrome. If anyone can think of any other things that could be the problem i am up for suggestions. I have tried gravity feeding, power feeding with a power bleeder, the ol syringe in the bleeder and reverse pumping fluid, and other things. I am lost! Please someone help.

I think you are correct about the master cylinder being too small. When you pair up an HD bike with an HD sidecar, the kit comes with a different master cylinder for this reason.
If you Google "Sidecar Forums" and ask the knowledgeable folks on the other main sidecar forum someone will be able to help you out.
