Ok so some of you may know, I have had my car for about 5 weeks now and almost everytime i get out and walk to the Passenger rear tire i can smell a very faint burning sell;crap. It smells like umm like burning tire/brake smell only from the rotor. Its definentaly not a sweet smell like burning coolant. No dummy lights on the dash, no sounds when braking just a very faint almost un-noticeable smell. I first had someone tell me about this when they got out of the back seat. Its for sure not from the engine, i checked that as soon as i smelt it. No smoke. I was thinking along the lines of using caliper lube the next brake change, good idea? Its only from that one tire too. No smell inside.

Thanks, alot.

It could be a dry slider pin, a bad caliper or a shoe dragging in the brake drum. You could pull that one wheel to check it out and lube the slider pins.

it sounds like a caliper not fully releasing. take off the wheel and try to spin the rotor by hand. if its a bit of a problem to spin or dosent freely keep spinning, its your caliper most likely. which you could either rebuild OR just replace. they are cheapish so i would just replace it honestly. and the pads since they are rubbing so bad. wouldnt hurt to probably at least turn that rotor if not replace it as well.

I picked up an infrared thermometer at Princess Auto (Canada) for like $50 and I use it on such things as brakes after I pull into the garage. Simply walk around the car, point the laser at the rotors and they should all be approx the same temp. If one is 100 degrees hotter than the others than that is the one to service.
You can also use these IR thermometers on things like:
- checking window drafts in your house.
- check exhaust temp.
- rim temps
- even see if the food is still frozen.

Might not be a bad tool to invest in.

Just my 0.02

Mine looks exactly like this one:

Of course it has another company logo on it, and it is 12:1 ratio and I only paid $50 at Princess Auto in Canada. But this is it. Very accurate and 1001 uses.
Enjoy.

Yes it does but they don't like it when you point the thermometer at them.

The IR thermometer sounds like a useful tool. I usually use my finger tips for crude comparisons. My Flute multimeter has a thermo probe for accurate readings.

I found one on ebay - $26 US shipped - http://cgi.ebay.com/Non-Touch-IR-Infrared-Digital-Thermometer-32-to-300C-6_W0QQitemZ280292163637QQcmdZViewItemQQptZAU_Gadge ts?hash=item280292163637&_trksid=p3286.c0.m14&_trkparms=66%3A4%7C65%3A15%7C39%3A1%7C240%3A1318

There you go...
Can't beat it.

So, to get back on track for this thread - The smell coming from the back wheel may be because your caliper is sticking a little more than the other wheels. So, meter the rotor temp compared to the other three and if it is hotter then simply service that wheel. I don't think you need to replace anything, just service it for smooth operation.
