Before you ask, yes I've extensively searched with no luck in regards to finding a quick solution.
Anyways, here's my problem.
On my way home from work today I caught the scent of what I thought smelt like burning brakes. Thought it may have been a car next to me, or some big rig ahead of me in traffic. Get home to check my brakes visually, and noticed extreme heat from coming from my front drivers side brake, but not the passenger side. Obviously there was more brake pressure being put on the drivers side rather than disbursing the force equally. Eventually pull the wheel off to visually check the pads, everything seems to be fine and there is plenty of pad life left. Put the tire back on, and took the car out for a spin. Went down the street to do a few quick braking spurts with my hands off the wheel. Didn't notice any pull to one side or the other what-so-ever, problem seemed to be fixed. But now I noticed, that only when I brake really hard an indicator light comes on in the dash. It's red, and looks like a oil lubricant canister. Checked the brake fluid itself and it seems to be fine. Fluid is not at Max, but more so at the Min level. I havent touched my brakes in months, so I'm assuming there shouldnt be any leaks and if there were i didnt see any. Any insight would be appreciated.
Thanks

Glad I'm not in the dark here haha. Upon further investigation, I noticed that without applying pressure to the petal, and going <5 mph, it would stop on its own. Meaning, the brake is sticking. What's going on here? I havent done anything to my brakes in months, and it all of a sudden started today.

Might have a sticky caliper, and the oil light is representative of low oil in the car so under an extreme stop it can come on as the oil has sloshed forward possibly making the sensor think "Where the hell did all the oil go that was here just a second ago?" . When you did your brakes did you bleed the brakes at all? maybe try bleeding a little through and see if that can help anything, if not you may need a caliper.

Alright, so I've concluded that my problem is a sticky caliper. What I ask is, what can cause this to happen, and is this covered under warranty? Because honestly, replacing a caliper shouldn't be under the normal wear and tear items. Any insight on this would be greatly appreciated thanks.

Well this is a bunch of BULL SH*T. Took the car into the dealership yesterday, only to wake up to a call this morning from the tech service statement that BOTH my calipers need replacement. Not just the one, but both Because the service tech said the other side was sticking as well. Don't you think I would have noticed that? And now they want to charge me $977 for a brake job. Christ, it's calipers, not pads and rotors, shouldn't that be covered under warranty? Toyota Corp. is definitely going to get a call over this one.

everytime i see this i always ask when the last time someone lubed up the sliding pins on the caliper. That is what I've seen causes this. But if the piston or the sliding pins are SEIZED in the caliper, then forget it, you need new one.

I wouldn't waste my time with new calipers from Toyota they're way overpriced on everything. try napa for some calipers. just checked for an 07 tC.. $72 + $39 core (refunded when you return your old ones to them). that's for each caliper.
$977? tell them it was their fault for not servicing them at the 15,000 and 30k services. but good luck arguing with toyota, doubt you'll get anywhere with them. Better off spending the $72/each and fixing it permanently.
but I keep telling people you gotta lube up the sliding pins every year or two on this car. They seem to need it a lot. Design must be causing it.

Thanks sciontc_mich, im gonna do a thorough inspection today on my brakes. Gonna bleed the brakes and getting new brake pads while im at it. Most likely itll be a sticky caliper. Thanks for your help everyone. Much appreciated.

Alright, quick update.
Haven't made an effort to contact corporate about the situation, but in the mean time I fixed the problem myself. All I did was go down to the local auto parts store, buy two caliper rebuild kits that only consist of new O rings and seals. Pulled everything apart, including the cylinder from the caliper itself, cleaned off the residue (black in color) from both cylinders, lubed everything up and put it back in with a clean re-bleed of the lines. Since then have noticed no problems what-so-ever. Brakes work perfectly, no sticking issues at all and have even noticed a dramatic increase in gas mileage. Total cost to me was $27 bucks. No need for new calipers, they shouldn't ever have to be replaced anyways. All is said an done here.

YAYYAY YAy!!! I finally figured it out! So i removed the brake caliper and still noticed that the rotor was spinning just fine.. As soon as i put the wheel bolts on the rotor would not spin at all!! Turns out i have a bent Rotor -_- . GOnna buy a new one. Problem should be fixed. I guess i jumped to conclusions about the sticky caliper... as far as how the hell the rotor was damaged..no idea.
