Very good video. Just changed mine today (7/4/23). My pads had about 8mm of meat left but were starting to separate from the back plate. They were Pagid pads and discs from Eurocarparts. I wouldn't recommend them. Just replaced them with Brembo ones. Top tip don't over grease your sliders on the carrier. Too much grease will restrict the travel between the carrier and caliper. This will cause uneven wear on your pads.
Had to comeback to this vid as I've got my wheel off and thought I needed to undo that massive bolt but you just knock the disc off from the back. Cheers....just need to change inner tie rod while I'm here now😮💨
