I have a 2007 Gmc Sierra SLE ext cab 2wd. Today, I replaced the stock 17" rims and tires for a new set of 20" rims and tire (305/20/50) Truck rides and drives like a dream except when braking above 40 mph. Truck feels like its falling apart and mechanic said I had warped rotors.I believed him. Replaced both front rotors and pads and still did not help! Now when I stop I can feel more of the vibration towards the rear. No bent rims and tires were checked for balance twice today alone! Brake petal vibrates and truck feels like it coming apart when braking! Truck only has 43, 000 original miles and is well taken care of. No dash warning lights are coming on. What could be causing this? Scary.
have the same problem?
