I took my car in to theshop because I was hearing grinding noise coming from my left rear wheel.
Apparently, I thought the brake pad in the back was wearing out because I saw a deep circular scrape mark on the surface of the rotor.

I took it in and I told them to change the two rear brake pads thinking that was the problem. When I got my car back and started driving, I was hearing the grinding noise again and this time it was even louder than before.

Do you think it is my rotor that needs to be replaced?

 

I would say replace them, there not to much money and you'll be glade you did in the long run And the pitting could possibly be from the pads bein so worn down that they started grinding in to the rotor there fore leaven a nice grove all the way around the rotor.

can't they turn them ??? normally they can put them on a brake lathe and turn them to make them smooth

 

Depending on how "deep" the scoring is will help determine whether or not the discs need to be changed out or just rotated.
This is the best excuse to buy new ones though, lol.

 

Well, I went back to the shop and they replaced the two rear rotors. My two front rotors also look worn as well. I probably should have them replaced as well.

 

if u r using stock rotors there is no sense in turning them...its a waste of money and u lose far to much colling capacity...its not much more 4 a brand new rotor...DONT EVER TURN UR ROTORS PLZ!!!!!!!!!

 

Hey.

I posted another topic about this issue. Well, I had brand new rotors installed in the front along with brand new brake pads.

But I am still hearing the screeching sound when I brake. Any suggestions?
