Maybe it was one of them cheap transfer boxes they fitted.
Well it's a main VX dealer, done under warranty. They even offered to replace front brake pads + rear pads and discs for £400- that was with none VX parts to bring the price down!!
Apparently, the pads are almost down to the metal, what they didn't know was that I personally stripped and cleaned the front brakes a matter of weeks ago and the pads over half thickness!!
I've just priced up the brake parts at £140.
