let me know what you're getting mate.
get a repair kit for the caliper and repair it mate and then measure the discs thickness post it here and take some photos of the discs and post them here to, the repair bills are jokers so treat them like that. Depending on how you drive you need different set of pads, discs , fluid, lines etc.... think there was a front set of calipers going for 200£ not sure if they sold.
