yesterday, I dropped off the Vauxhall HB SL axle to a fellow HB owner (it is too light for the GT). Before it went, I scavenged a couple of parts, including the slave cylinders. As I removed them, I noticed that one axle cylinder had a brake line in and a brake line out (not a bleeder) Upon inspection, I realized the brake line came from the Master, went to the one slave, then to the other, then to the bleeder. In other words, theoretically, you should only have to bleed one side on the back to have them all done.


I have never seen this arrangement before but it was curious. It seemed like a convenient way to ease bleeding but, potentially an unsafe situation as one damaged hose instantly empties both sides. (which is I know why they went to dual circuits)
 
My Lima Series II has the same arrangement. That hydraulic routing was also used on the Ford Capri.
 
On solid axle TR4A's the brake lines are done like that too. The LH wheel cylinder on the LH brake drum has a hard line entering from the MC, then a hard line exiting and traveling over to the RH wheel cylinder. Bleeding the rear brakes is done with that one bleeder on that RH wheel cylinder.
 
That's also the same way my Jensen Healey is set up. One line from the master to the rear left, and then a hard line from left to right, with the one bleeder at rear right. I believe it's a Vauxhall Firenza rear axle, which would add some continuity to this discussion.

I believe you are correct about the axle - BTW, do you have a two piece drive shaft? and if so, is there a source for the rubber donut that supports the centre joint?
 
All my Cortinas have been that way. Look at a set of brake hoses. Three required only, ha ha
 
No, mine is a one piece (the two piece shafts were used on the later Getrag 5 speeds). But, if anyone can tell you where to find it, it would be these guys. They don't show it in their catalog, but they can find most anything. https://deltamotorsports.com/products/pg7b-rear-axle.html
