Today I noticed my 03 Tahoe z71 right rear brake smelled very hot after driving about an hour. I got home took it all apart and found no seized caliper, brake pads are good, slides are good. Everything looks great. I put it all back together and went for a drive. I drove 15 mins and then my left front was so hot I couldn’t get close to it, found excessive brake dust. Slides move freely. Figured I’d order a caliper and hose. I drove 15 mins home and my right rear is super hot again and my left front is ok. What the heck is going on lol
