Thanks for the reply. I have had the car since about 10000 miles and it always has made a noise like warped discs from the front like a grinding noise I have changed the discs and pads up the front twice trying to fix it with no luck until the rear discs and pads needed replacing and to my amazement after replacement the noise is gone. The only two possibilities are when I got the car it had been parked up making the discs corroded and the dealer said they put new ones on so it either was cheap discs or maybe they didn’t just cleaned them making them warp. I am just pleased to get to the bottom of the problem.
