All right guys need some real help.... My brakes are so so so shit and don't even get close to getting the tyers to lock up. I have had a mechanic go over it all day and has checked everything and the only thing he Didn't touch is the booster? has anyone else had theses problems ?? I run 285/75/16 Mtz and tow the work trailer everyday. Need it to be able to stop any help would be great.
