My car recently had a flat, which seemed of no real reason, new tire etc. But when changing it, the rims were extremely hot, burning, when the front rims were not. I put on a new tire and even put on new brake pads, however, I still feel the rims burning hot after driving when the fronts aren't and smell a weird smell.
Seized slider pins ? - or e-brake cable - you have to make sure the operation of that caliper is proper. slider pins have to move freely. Check for bearing play. brakes and bearings are going to be the source
