Hey I need some suggestions on how to remove a rounded bolt head on the rear brake caliper on my 1996 Honda Accord. I went to replace the rear brake pads and had no problem removing the bottom bolt from the caliper but the top one was rounded off. It is a 12mm bolt and I cannot get it off. There is no space to do much to get it off which makes things more difficult. Any suggestions on how to get this thing removed? Like I said it is in a tight spot. Any ideas are appreciated. Thanks!
