Mild smell of rubber

[Burn]

Ok so coming back from the store, about 30 min ride, I notice a slight smell like rubber or the smell when a hauling unit / truck tractor gets on the brakes to hard in front of you on the highway. Looked over everything as well as I could, did not seem to be a belt was more from the rear anyhow like when I opened the cargo area, any ideas.

Brake lining perhaps. Tranx/ trans. Driveline.

Trash or plastic from the road get caught underneath around an axle, exhaust, brakes, etc? Parking brake not fully disengaged? Newly frozen caliper?

Wow, that narrows it down, :gaah:lol, I'll drive it again see if I can duplicate it an pinpoint the area if not guess its going to my mechanic.
thanks for the quick replies.
