My rears are actually going hydraulic to match the front.
The fronts have been dogged by twitching to the left under first hard braking (after the first stab they're alright for a while, if frequently used but it doesn't engender confidence). I reckon this is the front cylinder on the right hand side being a bit lazy (seems so under test on axle stands.). It'll be replaced. I also suspect that it's exacerbated by strong brakes at the front only, making the car more nervous. And the diff was leaking through a gasket so I needed to address the axle anyway.

Charles, I would look at air in the system, the brake cylinder that points upwards is notorious for trapping air - the in/out is located at the bottom of the bore (all the others, when in position are orientated the other way up) and it is difficult to fully expel all the air in this situation (removing the back plate off the hub temporarily and bleeding these on their side would allow the air to escape) and air being more compressible than oil would account for its laziness - also, if lazy then it is more likely to suffer from corrosion in the bore which makes matters worse!
The rears should be mounted with the piston acting downwards for the same reason, i.e. the in/out is then at the highest point and air can be properly expelled, the hand-brake lever is then pointing downwards (same as on a Morris Minor), lots of cars have this the other way up, but that adds the same bleeding difficulty!
I have hydraulics all round and the brakes are very effective and do inspire confidence!
