need some help :(
Hey everyone, my car just recently threw a service light and showed the rear end of the car and the 'brake' light illuminated in yellow. I know I have to replace my rear pads but do I have to replace the rotors as well? And do I need a new brake pad sensor or whatever it is ? Please help, its my first time that I have to do this without warranty. Thank you everyone

That light is tied to the brake sensor. Are you sure it's the pads and not just the sensor? Look at the caliper and see how much pad is left.
How many miles on the car? Have brakes ever been done? That said if you do have to replace pads and/or rotors, I recommend OEM parts. They work great for street use.

Well... I replaced my first set at 55k mi and the dealer said it was unusually low and the second set lasted 80k mi with 2 track days. The fronts lasted 80k mi on the first 2 sets. 3rd set is unknown because I swapped the calipers. I'm still using the 3rd set on the new calipers front and rear.

Yeah, that is really bad, the brake bias has to be off somehow.

Idk why my car is like this, it kinda confuses me cuz my rears has had more changes than fronts. I've only replaced the fronts twice and they didn't even throw a light, it was about 1k miles before I needed to. Should I be concerned? And my rear brakes shoot off an enormous amount of brake dust. Usually my whole rear bumper is covered with a layer thick enough to write on it with your finger within 2 weeks. What could be the problem?

The uneven wear is weird. I wish I was more of an expert in this area to help you out.

Talk to the techs and the dealer and see what they say.

35k is really low for the fronts too. You should get minimum 50k out of the brakes and there should be minimal uneven wear left to right. Front to back is a different story. My car cakes up brake dust very quickly also. In a week my wheels are brown, but I drive a lot more than you I think.
