My Patriot had between 32K miles when the front pads and brake rotors failed. All conservative country miles. No stop and go city streets, or hard stops. No warning squeals from pad wear indicators. The rotors could not be turned. The ouboard pads had 1/4" of material left, but the inboard pads were down to the metal. Strange considering the caliper supposedly floats on the rotors.
Tonight, at 33K miles, I got a squeal from a rear pad wear indicator. Same scenario. Plenty of outboard pad, no inboard pad. I suspect the rotors are scored on the inside. Haven't had a chance to get the wheel off to check. Too cold, and too much snow.
I believe the Patriot traction control has a problem with cold temperatures, and or salt, and causes the rapid deterioration of the bakes. I just got two new control arms, tie rod ends brake pads and rotors on the front, and anticipate buying new rear pads and rotors this week. On a car that only has 33K miles on it, and has never gone offroad. This is not what I expected from Jeep!
