Cheers Alan - I will ask them. When I took it back on Monday I was within the 10days partial re-test period and he tested the brakes without logging onto the system so that if they still weren't right, I could take it back again for a partial re-test. Unfortunately the 10days has gone now so I need a full test again, but I'd rather know the brakes are right before doing that if I can and I'm not sure how I can check they are without doing the test - they FELT ok to me on Monday, but they weren't!!
I'm happy to pay for the brake test - provided it isn't as much as the MOT, otherwise there's no point. Will ask and see what they say. The guy seemed decent enough - he was constantly apologising for failing it - which was hardly his fault!!!
