I popped into the local one on the way into work the other day - focus st rear pads.

Me in my shirt and tie -

Yes sir that'll be £80 ( actual cost for me to do it was £18 including buying a rewing tool and it took ME an hour and half in the rain on my steep hill of a drive way with a halfords socket set. )

But sir if the discs (which are ok) have been grinding then we'll have to do those as well.

Oh right and how much is that?

£250

Its ok - you need not check.

That my dears is a RIP OFF
