Default Brake noise

Just got a 350z and recently it has started to make alot of noise breaking when below 30mph. I took off all 4 wheels and inspected the pads, but they seem to be fine with pleanty of pad left. Any seggestions on to what the problem might be? Thanks

can you describe the noise? Judder / vibration? squealing? scraping? metal-to-metal?

do you feel it vibrating in the steering wheel, or brake pedal?

Brakes will get to the point that they will glaze. The Pads and the rotors will get a glass like finish and simply lose their Bite. If there is plenty of pad, then there is an indication that the brakes are used improperly and allowed to remain in contact for too long of periods of time. Heat and Pad/Rotor contact will cause glazing. Rethink your breaking habits, I relize that everyone in the world has proper breaking habits, but just do it for a laugh.

If your glazed, you have 2 choices 1) New Pads and Rotor turn 2) If you have the expertise and PLENTY of pad, take them down and using a flat surface, lay a sheet of 320 or so paper and "Lap" them in a figure 8 motion til you break the glaze, then do the rotors by using an orbital sander with 320 disks and deglaze them. reassemble and do a SHORT bed in.

I think they are glazed, because when I took off the front wheels to look at them the rotors were somewhat discolored. Thanks

discoloration can be normal, the pad material forms a layer on your rotors. If you can describe the noise, we can help more.

its a high pitched squealing noise, and oddly it seems to have gone away. They didnt make any noise today.

what is a "short" bed in, or any bed in for that matter, I think im going to sand my pads and rotors this weekend to see if that fixes the problem
