I took the E to the dealer for a crack windshield. Of couse they found a impact. Plus I was tired of hearing the breaks adjusting or click when I was reversing. The dealership happened to find a up date to fix the problem that thay said was normal. My invoices says:

410150 replaced front brake pad lower retainer clips (S/B 03-033)
219 WF 0.070
2 -A01 Clip,
pad
FC: 03214/04213
Part #:45237-S9A-003
good luck

JFYI disc breaks do not adjust, they self adjust every time you apply the breaks,,, changing a break pad is a noise fix-all (usually) to keep the customer happy. sounds like you have a decent place to take your car for service at least
cheers
