To be fair the worst pad was about 75% worn but they did the usual garage thing saying the discs are marked and could do with changing but today wasnt a bad day, dry at least so I thought I get some pads and fit them.
I just went to the local motor factors as he had some mintex replacement pads in stock, fitted them in about 1.5hr and that with taking photos for a "how to guide", having a sticky guide pin, cleaning the calipers down and going to pick them up from the shop and two cups of tea
Absolute doddle really, dont pay anybody to do this for you if you have a spare hour one day.
