Only happens when the brakes heat up a little more then normal and sounds like intermitent metal to metal friction that changes with driving speed (slower and faster) but does not change whether your on the brake or not....once brakes cool down it goes away....anyone experience this? thanks Greg

 

nissan disks and brakes...thanks

 

Your pads might be low and your discs are probably warped causing brake debris to get caught in between making noise?

 

I guess that may be a reason...so new disks would be the only solution?

 

That or get them machined and new pads.

You'll save yourself money in the long run by upgrading now. If you machine them now you'll be doing it again in the next six months depending on your foot to pedal habit. Recommend getting some new slotted rotors and hawk pads.

 

Make sure your backing plates are not touching the rotors. Also check to see if the pad shims are installed on the backs of the pads. If not, this tends to lead to squeaking pads.

 

I had the rotors cut and new pads put on and it did not fix the problem. I have shims on the pads, so I'll check if the backing plates are not touching the rotors. thanks for ideas
