Well I don’t want to burst your bubble but you couldn’t even buy those parts for anywhere near £200 so for your bloke to supply and fit them for just £180 all in, that has got to be the bargain of the century. Are you 100% sure? Why were the callipers changed? Also, I can’t ever remember seeing a KA with rear callipers so I don’t know how they found your ones to be okay.The pads discs and calipers were replaced but only the front two caliper as the back two were in good condition.
