Ok, I am working on replacing my wife's front brakes in her 2006 Montana SV6. One of those rubber boot things has a hole in it. I went to O'Riley's and bought replacement boots. They have a metal band around them. Part number is 30016130A. The metal ring around it totally doesn't fit in the bracket. It's too big. I put the after market ones next to the old ones and they look different. I called AutoZone and asked them. They said they show the same part number. I tried taking a socket and putting it over the metal and then hitting it with a hammer and I broke one of the rubber seals doing that. The original ones fit in the bracket and they're not tight. The ones from O'Rileys are too big. I'm going to call the dealer and see if they show a different part number. The car is dead in the water until I figure this out.
