Last summer my tundra started doing a horrible vibration on the highway after several miles. It would shake the whole truck like I had a flat! It went away for a while but one day coming home from work (4 miles away) it started doing it. When I got home I got out and all I could smell was burnt clutch that did not seem to ever go away. I pinpointed it to my rear driver side wheel, where the smell was coming from the strongest. I started looking at tundra forums and read the parking brake cable has a funky adapter where it splits the cable to both wheels. I generously lubed it as the information I read told to do so. I got new hankook dynapro at’s put on in the fall and haven’t had a problem in the cold temps. Well today on a nice 60* day on the highway the dreaded shake was back. Although not nearly as bad, it was there. Felt like it was coming from my seat, shaking the whole truck. I was worried as I had a truck full of family and my precious little 14 month girl. I started playing with the parking brake and brake pedal and it seemed to have come out of it. I’m guessing I have a warped rotor at the least. Do calipers warp if they get hot enough? Is it ok to replace just one caliper? If I replace the rotor, should I slap on new pads also? I’m budget conscious so I’m looking at eBay for a pad and rotor kit (all 4) for $160. Rockauto has a caliper for $40
