I know this is to new for the bolt page, but I thought I would ask anyway. My father-in-law has a 2005 GMC truck and the brakes squeel when you start to back up. It is very anoying to say the least. He has had it to 3 different shops and everyone says the same thing, Thats the nature of GM trucks. Does anyone have a suggestion on what I could do to stop the squeeling? The truck only has 25000 miles on it and the pads look new. Thanks in advance.
