[Healeys] Dual Circuit Brakes

[warthodson at aol.com]

As far as I can tell, the XKE has a front brake master cylinder & a rear brake
master cylinder. I am not aware of any brake system with two lines going to a
single caliper.  The XKE has an unusual (to me) type of brake booster. It is
vacuum operated & applies pressure directly to the pedal assembly. It is
called a "pedal assistance" type of system. As far as I can tell, there is no
brake line or hydraulic system going to or from the booster.
I have two original XKE work shop manuals (and no XEK's), would you like to
buy one? Contact me offline.

It is kind of weird to me.  One of the reservoirs goes to the master cylinder
and one goes to the booster.  Any of you XKE experts feel free to chime in.
There is definitely only one brake line that goes to each of the front brake
calipers.

I am not sure I understand this. Does the XKE have two brake master cylinders,
one for each reservoir? Or only one master cylinder & two reservoirs? If two
master cylinders, is one for the front brakes & one for the rear? If yes,
wouldn't that be dual circuits? If no, what was the intent?
