Took the Morgan for a run and did several emergency stops.
The rear improved both braking evenly.
The front also appeared to be better as well, which points to lazy rear cylinders and possibly grease on the discs though I do have gaiters.
I find the brakes on the +4 very unresponsive with little feel unlike my older 4/4's. Light pressure has very little effect and the danger then is that you stomp on the pedal too much.
I will take the advice of the forum and fit braided hoses and better pads when the brakes are overhauled.
Occasional heavy braking will also be added to the to do list.
