I put new pads on several months ago. They screeched when stopping so I went through the bedding procedure and everything was fine. Lately the screech is back. I tried bedding them again but the screech persists. It happens with light brake pressure. If I do a sudden stop, there is no noise. Happens hot or cold. It's hard to tell if it's front & back but I'm positive that at least the rear ones are involved.
The rotors have about 10K on them and look great. I removed the pads and they look fine too. The car stops fine.
I've read other threads about this problem but didn't find anything that seemed to fit.
Any suggestions would be much appreciated.

 

What kind of brake pads are you using? Is everything lubricated well?

 

They are Wearever Gold Premium pads. I haven't lubed anything. What specifically should be lubed?
Thanks for the reply.

 

Using brake grease, lubricate the guide lands on the top and bottom of each pad; it's where the retaining clips slide into on the pads.

 

Will do. Thanks again for the help.

 

I have had the same thing happen. It only happens occasionally when I am applying very light braking, any additional pressure and it stops the little squeal.

I suspect it is due to replacing the pads but the rotors although still having life left, were not. I bedded mine right away.

I wouldn't be surprised if you re-bedded them again it might go away for a while again.

On the next pad replacement you'll probably need to do the rotors too, and that will solve the issue.

Personally, I use AC-Delco Durastop so the pad brand isn't the issue. I believe it is a symptom of a mid life rotor and new pad combo. I wouldn't worry about it, just apply a little more pressure on the brake to silence them. I think the new pad silica is just not able to clean all the glazing off the wear of the rotor and thus causes the squeal.

 

Jet Jock, the rotors have less than 10K miles on them. I replaced them because one was warped. The pads were still good at that time but with hind sight I should have just replaced everything. I tried bedding them again last week but the squealing persisted hence this post.

 

Drop in a new set of rear pads. Bed those and you should be good to go.

 

My 03 Coupe had developed an annoying brake squeal over the past few months and I intended to apply some brake grease to the guides and make sure the clips fit tight as soon as the weather was good. But last week I got a good deal on a new set of Hankook Ventus V12 EVO tires and after the shop installed them I had no brake squeal. The shop just balanced and put the new tires on, nothing else (I watched). The tire guy did clean the surface rust off the face of the rotor with a wire wheel brush so there was nothing between the wheel and the rotor but I don’t think that made the difference. The tire guy did use a digital torque wrench on the lug nuts, something I never do. Once out of the shop there was no brake squeal at all, I had a squeal on at least two wheels before.

I imagine that the brake squeal may have come from lug nuts that were not properly torqued down and somehow the slight vibration/imbalance led to a brake squeal???

Or, maybe that a couple of my old tires were so worn and out of balance that the vibration or the imbalance somehow caused a brake squeal???

I can’t say for sure how my problem squeal was resolved but if you have a persistent brake squeal that cannot be fixed with either brake lube, new pads, new rotors, or the bedding process. Then I would first suggest cleaning the surfaces between the rotor and the wheel & tightening the lug nuts to the proper torque specs, which costs nothing. If that doesn’t fix it then take it to a tire shop and have them check the offending wheel/tire for proper balance.

Again, I can’t explain it but it worked for me and I just wanted to share my experience so maybe it can help others.

Good Luck!

BTW, I have original stock GM rotors with 65000 miles and AutoZone brake pads with 10000 miles on them
