Burning Smell . .

Hi there!! Just kinda curious, for obvious reasons, what this might be - coming from rear wheel area (noticable if you put head into wheel arc) - but guessing its either wheel bearing or brake pads rubbing slightly. My money is on it being the brake pad catching - is there a way of adjusting this to stop this happening?? (I know they should auto-adjust .. . but I may be missing something) OR . . does it sound/smell like wheel bearings on way out?? (not too sure what to expect from dodgy wheel bearings - apart from them ultimately siezing!!) )

Cheers all . . .

strip it down and have a look

Yeah, I know thats what I should do lol . . but just trying to be lazy in the home someone has had similar experience. Hopefully got an easy 'work from home day' tomorrow, so get chance to look then . . . .
