I'm trying to uncouple the rear brake hose. Unfortunately, the metal bracket is deformed and preventing me from sticking a socket into the 10mm head to remove the bolt. I didn't think to snap a picture at the time because I didn't even realize the bracket was deformed. Upon searching I found the below picture of how the bracket is supposed to look like. The bolt I can't remove is the one in the "middle" just above the bolt holding the hose. The lip around the top of the bracket is pressed down thus preventing the insertion of a socket to remove bolt. I had tried to raise the lip back up by twisting with a flat head screwdriver but it didn't budge at all. Now that I know it's deformed, tomorrow I intend to try some pliers or maybe even a flathead screwdriver with hammer to try to move the lip back up to make some space. I have no idea how it could've gotten squished down. Any other suggestions that I could try?
