I finally need new brake pads on my '99 A4 1.8. Any tips on the removal of the calipers? I took a quick look yesterday and the only thing I wasn't sure about was getting that large spring clip off. Also, any tips on types of pads? I made 95k on the original set, so I don't have any complaints about them. TIA Joel L '99 A4 1.8tq Avant - 93k '96 A6 2.8q Avant - 100k
