Maybe a little off track but I found out if you order parts online from halfords they get them from Eurocarparts , so saves driving out to Glasgow to get bits from europcarparts , open late and even better if you have a halfords trade card ( but only discount on halfords service parts like in stock filters).
On another note I have always used paddocks for discs and pads, also if you spend above £50 free P&P I normally buy new caliper bolts, pad retaining clips + split pins and new hub bearing seals.
