Fronts were easy, same as a D3 but look slightly different. My pads were absolutely jammed solid in the runners, not seen any like that before. What I did find though was even a slight amount of rust/corrosion behind the spring clips made them very stiff, so I trial fitted with the carrier in my hand to make sure they were nice and smooth running. This was a lot easier than trying to do it with the carrier fitted.

I am so relieved it's not just mine! Look at the uneven wear on the photo below. Both front wheels were the same and the top lug on the inside pad was most jammed on both sides. Not only had that pad worn down quicker, but the lip on the inside of the disc extended in a wedge-shaped profile about 20mm in from the edge. The discs were only 30% worn, so I had them skimmed to remove the lip before replacing the pads. I scraped and filed the rust off the recess in the carrier where the shims sit, but still the pads were held too firmly. So I filed a bit off the pad lugs, too, until they were an relaxed fit in the shims. Then I dipped the lugs in copper grease before refitting. Front brakes are now working brilliantly and I'm keeping an eye on the disc profile. Next time I take the carriers off I'm going to Dremel them so that, hopefully, I can avoid modifying the new pads.
