It appears that one brake line only (Unlike my 55.1, No T block at the back of the master cylinder) comes from the master cylinder, then crosses the rear crossmember to a T which goes forward to another T, I assume to cross the front crossmember to get to the LF Wheel.
Can anyone confirm this?

Thanks!
