Another one here for DIY service, it’s not difficult, just take your time. I had the brake pads and pins out a couple of weeks ago, I just had to lightly sandpaper the pins, as they get tad of oxidation build up on them, then a smear of anti squeal paste and reassembled, pads were all good. It took less than a hour from start to finish. The value check is probably the tricky one, but again just take your time, and recheck your readings. The wetheads almost never go out of spec on the value clearance.
