Morrisminor, you don’t say what your car is, but I am assuming that it has coupled brakes. Normally, adjusting the front brake cable will not affect the rear cable adjustment. Indeed, on coupledbrake cars, it is required that the front cable is tighter than the rears to ensure that the front brakes come on first and that there is greater braking effort on the front.
I had a similar problem on my RP when I first had it and found that the brake cam pivot was partially seized in its bush. Getting the cam out is a bit of a pain, as the hub has to come off, and, at that time, I didn’t have a hub puller. So I poured. Copious quantities of penetrating oil to the rear of the cam and the lever, disconnected the cable and turned the cam to and fro until it became perfectly free. I always run some oil down the back of the rear cam levers when I do a service as there is no other way of lubricating the bushes. (Yes, I know that the bushes should be ‘oilite’ but I don’t trust anything that is supposed to be self-lubricating on a vintage car.)
