Got it all sorted this morning.
Went down and talked to the manager and after looking at it again, he said the caliper was sticking when my car had been running over 10/15 minutes.
So he says I needed a new caliper , disc and pads. Caliper at £76, disc £22 and pads at £22
Labour charge of £67
How does this sound?
Also they cheeky thingy, charged me £5 labour charge for changing one lightbulb
