a little less than a year ago I replaced all the rotors and pads... . It started to slowly show some warp age on the new brakes... . then my caliper went and locked up it turned the rotor blue so I assumed that was the bad rotor so my rotors had a 2 year warranty and the pads have a 3 year I warrantied the single rear rotor and by god the pulsing is still there..... so now Im going to have to warranty the other 3 rotors and get new pads since they are still under warranty... . will this streak of bad luck ever stop on this truck... btw by bad luck I had to replace the steering ,the brakes and now my exhaust just cracked on the way home from work all in 2 months :{:{
