Does anyone have detailed instructions on replacing the brake booster in a 2010 CX9? I found these http://www.justanswer.com/mazda/8w7qo-mazda-cx-9-grand-touring-how-remove-install-brake-booster.html but one step says to remove the windshield? Do I really have to take off the whole windshield? I'm doing this because the extended warranty for this only goes to 90000 and I'm at 93000. Go figure that the symptoms don't show up until I'm out of warranty. Dealer wants 600+ to replace it, so I'm sure it's fairly involved, but I'm not paying that for a part they know is defective.
