Yeah, so the subject line says it all.

The rear driver side started grinding out of no where with no warning. When I got out to check it out, I noticed some scoring close to the outter edge like metal is rubbing. The pad cant be done this soon, I've only put 9k miles on them since last change.

Is it possible something got stuck? Like a pebble?
Man... I dont want to have to replace the pads and rotors in the rear...

Anyways, its only that 1 tire that makes the sound. After it grinds to a stop and I start to take off it makes a clicking sound that gets faster as I accelerate.

My guess is that I need to replace the pads & rotors in the rear. Whats the cheapest I can find rear rotors for?

 

my rears were warped. i went with a place called drt for the rotors. they came out to about 130 for both crossdrilled and slotted.

 

That's weird if only one of your rear brakes has grooves in the rotor after only 9K miles. But i've seen some odd things happen to brakes, especially if one of the calipers was malfunctioning in some way.

That clicking sound kinda sounds like the TSB that came out about the rear axle needed to be repacked/relubed/whatever, but I've got a RWD 6MT not an X (might be different for that TSB). So you might look into that and see if that's the source of your clicking sound

 

My right rear caliper seized. Monro muffler wanted $800. I got an aftermarket for $120. This happened soon after the rear pads were changed.
