The simplest thing to do is grab the whole brake system off an XK150
(if you can get it), this will then make worries about biasing moot...
and your life a lot easier. This approach will mean that you get both
front and rear brakes so your other question is moot also :-)
If you get the 150 system it's basically a bolt-on exercise with perhaps
replacing the hubs and or odd axle.
I have seen this modification done (XK120 to front wheel disk not 4) by
using series III E-Type front brakes however this involved some serious
metal-work and is not reccomended for the faint of heart. Go for the
XK150 system.
Regards Scott.
