Thanks for the reply,no I'm not a complete moron,and I'm fully aware that when the engine dies the power assistance fails,but on a two ton vehicle on a bend I would construe this as being dangerous ??.
The issue in this case is that the failure was sudden and without warning and could not be predicted by the driver.
If I wanted to spend my spare time patching up an old banger then I'd have bought one and taken it as expected when it broke down,but I didn't.
I think perhaps though I'm posting on the wrong forum given your attitude ,and as you have such a large number of posts to your name I'll say good bye and leave you to it.
