Had my clio in for mot today, got a list of bulb related crap to sort and the other thing is that ' service brake efficiency below requirements 47% efficiency.' - Rear What the f**k is the service brake? matey said that it might be because the back of my car is stripped out and there is no weight in the car. Thus affecting the rear brake compensator??? Anyone tell me wtf i have to do to make it pass? Matey said put some weight in the back of the car???
