Default Squealing Brake Pads (long)

Last fall, I replaced my stock rotors and pads with PBR ceramic and slotted rotors from ECS Tuning. Had done the same earlier with the rears and did not encounter any problems.

The fronts were quiet at first then began to squeal. I did the bedding procedure and all was fine for a few days. After some stop and go city driving, the squeal returns and unless I re-bed the brakes the noise will not go away.

Last week, I removed the wheels and checked for a loose caliper or guide pins that were sticking. Everything is tight and the pins slide nicely. I purchased some Wurth Disc Brake Quiet and coated the back of the pads and re-assembled the brakes. No change in the squealing. Did the bedding procedure again and it was quiet for one lousy day. The squealing has returned.

Need some recommendations on a different set of pads. Might just go back to a stock set as I did not notice any less brake dust with these ceramics.

Brake parts cleaner? If so, not for braking surface.

Thanks for the tip, Grapeking. I checked the cost at ECS tuning for these Hawks. Are there any other places these could be purchased (reliable business)at a lower cost?

Akebono ceramics are dead quiet and so little dust it's hard to believe. I won't use anything else.

I did some searching when I got them but ended up going with ECS tuning.

Default What was the procedure you used to bed in your new pads?

Many of us including myself have had issues with the PBR Ceramics. If properly bedded in, it should dramatically help reduce squeal.

Default Re: What was the procedure you used to bed in your new pads?

Used the "Stop Tech" procedure. Initially stopped all squealing for a few days but now it returns after stop and go driving. The brakes are super but the squealing and dust are far from what I had expected. Have the same set-up on the rear. Slotted rotors with PBR ceramics. These had a minimal amount of squeal initially but have remained quiet for over a year. That is why I ordered the same pad composition and manufacturer thinking all would be ok for the front. As long as I apply the brakes with more force than needed then the squeal will not happen but slowing down gradually to a crawl the car sounds like a school bus. I can't put up with this any longer. I'll have to try another pad.
