So I bought this truck used-I'm the second owner-with 116k on it back last August. It has run like a dream, towed like a dream, and the only issues have been a post-cat O2 sensor tripping the check engine, and the fact that it pulls to the left under heavy braking.

Today, the first warm day I've driven it, I got stuck in a stop-and-go detour. After about 20 minutes of stop and go, I started smelling a burning rubber/electrical smell. It was clearly coming from me. Closed the windows, and smell started coming through A/C... slightly.

Got home, did a walk around, and the front right-which I've always thought was the reason it pulled left when I broke hard, was RADIATING heat. That was also very clearly where the smell was coming from.

So, I don't want to go to a shop and give them carte blanche. I assume a fluid flush is in the cards for the brakes and maybe a new hose, but am I telling them to check the caliper? Am I popping the fronts off and swapping pads and rotors? Anybody had something similar on their G3?

 

It's not good to suggest anything without actually looking at the vehicle.
That said, consider this,
If,,,,,,,the calipers have never been replaced it's time, 10 years !!!
The rest of what you anticipate is a better way. Do the whole job once $$$ permitting.
Don't overlook the rears.
