Fault finding by substitution of parts
The difference in operation is definitly noticeable from the soft feeling pedal that our D1 had before, to the pedal now not stopping at a halfway point and slowly sinking further towards the floor.
There is no fluid loss so I can assume that the brake fluid is finding it's way from one circuit into another, past a worn seal somewhere, --- but where?
I now have another master cylinder to try and i will see what difference that makes, a process of fault finding by substitution of parts.
