JLP, I suspect your thinking is correct re the expectation of finding dual circuit brakes. I have not been involved in other than general brake maintenance on my Morgan, though I went out to the garage and the brake master cyl has two take off points which would suggest dual circuit, as might be expected of a car of that year. Without getting under, I suspect that the front brakes are a different circuit from the rears, as opposed to the more normal(?) diagonal front/rear split..?
