this is honestly a really hard question to describe. Do you know the screw where you screw the base of the brake into the chassis(? I believe thats what it screws into.) Well I guess the part that you screw into corroded away and now there is a quarter sized hole where a screw should go. I'm not quite sure how I should fix this, and if it needs further explanation, I'll add pictures of the area I'm talking about tomorrow afternoon. If you have any idea what I'm talking about, help is greatly appreciated.
