Thanks John - found it! Fluid level is OK and no sponginess - in fact as sharp as anything. All I need to do now is try to work out if it is the switch. Any tips?
Mike,
I think every one else covered this off.
I now use LED brake lights. I did it to be seen better, but I guess as they draw far less current they would be an alternatve to the relay.
I think in general Mogs repsond best to regular use even if the weather is poor. Letting them sit seems to bring this out in them.
John
