Rear brake rotors warping faster

I have been noticing my rear rotors and break pads have been warping and where just replaced less than 9 months ago by the dealer any thoughts. Not towing anything and just city driving.

 

What brings you to this conclusion???

 

Rear left break pad completely gone and warped rotor disc but rear right beginning to warped but break pad is wearing evenly with the front breaks

 

Sounds like you have a stuck caliper. My 18 right rear was sticking after 2 winters. The pins were rusted over. Try to put new pins in it. I ended up just replacing it. Calipers are around $115 and it takes less than an hour to do.

 

Will look into might be the reason I had never seen only one side be so worn out.

 

Could this be covered under warranty?

 

The traction and stability control will apply rear brakes too....

 

I’m pretty sure pads and rotors are considered a wear item and not covered under warranty. You could try a stuck caliper, but they will probably say the same thing.

 

Agree with caliper issue...brakes typically are not covered under warranty...they are considered a consumable.

 

Would seem to me that if the dealer did the rear brakes 9 months ago and your having these problems already, maybe you should return and discuss this with them. I can't imagine that much wear that quickly unless there's bad parts, (sticking caliper or ?) but if so the problem most certainly should have brought to your attention by the tech. I see a possible argument for improperly completed job by the dealer.

 

Over-torqued lug nuts can warp a rotor as well.

 

This^^^. And improperly torqued.
