8875 miles... S-tune pads worn???

UNKNOWN_370 · 10-19-2012, 08:55 PM

Today, I hopped in my Z. I took off my and I heard this hollow metallic scraping sound and an overwhelming squeal,simultaneously. I went back home and took my Altima to do what I had to do.
Came back and started the car and now the hollow metallic scraping sound was gone. The squeal was still very audible but not as bad as the first time? There's a very mild resistance at take off, but nothing to really compromise performance. Braking is still the same. Just mild resistance on take off and maybe while driving, but less than on take off. Audible squealing and only mildly progressive sound with speed... I'm thinking I need to bleed them and make sure they're functioning properly. Rotors are new stop techs were fine for 3,700 miles and never been tracked. Or, maybe I just need new pads already. 1 track day but nothing too extreme on my car that day before the stop tech rotors. 50% spirited driving. Thoughts anyone???

Where the rotors rusty by chance? Takes a few stops to clean them up. Take a look at the pads and rotors. Might just need to re bed them.

No sir, they're clean as a whistle. Maybe thats it? I'll check on that in daylight in the morning.

Could be some small rocks or road debris got caught in the pads. Go spray with brakeclean and see if it goes away.

I checked the brakes and I need new pads...

I am a little surprised it happened so soon... I guess my wife is right? I'm too much of an aggressive driver... oh well.

I had a similar screeching/grinding sound coming from my front brakes. My car only has 1,200 miles on it but I was driving and heard this insanely loud sound coming from the brake area. Pulled over and saw everything was clean as a whistle, continued driving and wiggled the car around and the noise went away. It must've been a rock or something trapped in the rotor or caliper.
