At first I thought it was the caliper because the right front wheel had 100x more break dust than the rest of the wheels. But the break dust seemed to stop some time ago.
I am planning on going to the dealer to inspect and do some maintenance on the brakes. I had that done on my 2003 GMC savana, and the brakes are much better than before.
Also, Im gonna have the steering checked, along with the struts and strut bearings.
The disc and rotor that i know are not in very good condition is the back left. For some reason, the parking break always sticks and it doesnt release the brake, so i some times drive with the parking break 'mildly on'. Its not really stopping the car, but after about 1-2 kilometers it starts to make that burning smell

The disc is warped and rewarped lol. Now when I push the brake, it sometimes makes the noise that..a warped disc makes. Those brakes are totally fried. This has happened to me about 3-4 times. Smokes comes out of the wheel.

I also have to change the bushings in the back suspension. When it rains, the car squeaks.
I think i need a new car
I guess thats what i get for buying GM.
