Doing a rear brake pad change on my Contemporary SE and first tried to remove the guide pins since this is the quickest method. I've a wide range of allen keys but I'm stumped with what size fits the pins - it's smaller than 8mm and none of my imperial selection seem to fit - what the blazes size is it?
I've now got the rear O/S free by removing the two calliper mounting screws but would like to dismantle the guide pins.
Both O/S pads are equally about 1/2 worn but I'm changing the rears because a) the December MOT advised "rear pads low"
b) the N/S started to make a scraping noise
I'll soon know for sure but I'm expecting the N/S pad(s) to be unequally worn, is there a common reason for this?
