Yes, I have the Chassis Service manual, not clear. I can go out and trace, really cold out. I am losing fluid from the front reservoir, so back brakes? All 4 wheel cylinders, master cylinder, maybe a hose and the two rear lines from the hose replaced with Nickel Copper lines. Thanks

 

Front to the front, back to the back. And if you are loosing fluid but don't see a leak, suspect an internal leak between the front and back pistons in the M/C.
