Good video mate, this doesnt look too difficult. I nees to get my calipera off and give the some paint and put some new discs on. Iwve got a few squeeky pads aswell. I noticed you giving the areas where the pads sit extra attention, is this rhe casue of squeeky brakes? Look at what your doing i bet theyve never seen any copper grease judging by the sound of them.
