I have a 06 911S with 45500 miles. Every time I put decent pressure on the brakes they squeak. This started yesterday. Any chance this is caused by dust or is it time to replace the brakes?

 

If the pads are getting thin then it's probably time to change them. If they still got some meat to them, then they're probably just dusty and need cleaned.

 

I doubt it s dust on these types of wheels....dust squealing was big on rear drums which we obviously don t have...... check your brakes.

 

If brakes are in good condition, ask your mechanic to shim the pads; brake noise mau occassionally be caused by pad vibration

 

Crap. How much is this going to cost?

 

Couple things could be going on:
1) Your pads could be glazed. Lot's of city or stop and go driving will do that. Try hard braking to burn the glaze off. Get up to 40mph or more and jam on the brakes very hard. Then do it a couple more times. Obviously, be careful that nobody else is around.

2) At 45,000 miles you might be due for new rotors. If a lip/bead has formed on the disc they will squeal more.

3) It's possible, but not likely, that the anti squeal shims are no longer stuck to the pads. That's an easy fix. Just a can of anti squeal spray applied to the back of each pad.

It's likely not dust.

The worst case here is that you need new discs. That's a few hundred bucks. A pair of OEM discs is about $350 for parts. Not terrible.

Good luck.

 

Awesome. Thanks man.

 

I replaced my pads at 50K --- yes, they were almost at the sensors.

BTW, I agree with most of the post above, except....
At 20K-50K range, my brakes made noises also but only when they were dirty. I quick weekly hosing made the noise disappear.
