Just replaced all four stock brakes (@ ~14,800 miles, 2005 F150 FX4 S-Cab) with the Porterfields due to high pitch squeal, had the rotor work done as well, torqued everything to spec, and seated the brakes. Guess what? Still squealing after installation two weeks ago. Tried some anti-squeal products and they don't work. Brake dust is down but I'd gladly accept the dust back if it meant losing the squeal.

Any suggestions?

 

Did you put anti-sqeual on the BACK of the brakepad before you put the pad on?

I did that on my ranger and it make a world of difference.

 

No, I applied the anti-squeal afterwards and only on the back.

 

The anti squeal goes between the back of the pad and the caliper.

Also... Was that the first time you had the rotors cut? There may be a groove big enough that cutting them didnt get rid of it.

Good luck. I have noticed that the semi-metallic pads do squeal a little more.

 

Not sure what you are saying here, but the stuff needs to go on the back of each pad before they are placed in the calipers. It is to absorb the vibration. I used Wagner Thermo Quiet pads, they have a special pad the covers the backside of each pad. I have never had them make a sound.

 

Brake pads don't squeal... The rust, debris, sand that is ground into the rotor squeals. The squeal is transmitted through the metal backing on the pad, into the caliper housing, making a really awful squeal.

A clean brake surface, clean pads, do not squeal.

If you drive through a mud puddle you may start squealing as rust or sand in the mud gets on the surface.
It then gets embedded in the pad surface, insuring lots of sound for a long time.

One trip down a dusty road and your truck may start squealing.

The 'pad' cure is based on pads that are soft enough that the sand, etc. sinks into the pad rather than riding the surface and squealing.

Another cure is pads that absorb sound. Usually soft pads.

Another cure is putting the paper pads on the back of the pads before putting them in. This paper absorbs the sound energy before it gets to the caliper.

Another cure is putting the 'blue goop' or any heat resistant glop (Brake Quiet, etc.) on the back of the pad, again, to absorb the squeal sound being transmitted through the metal. This goop goes anywhere metal contacts metal, which is the way that the sound is transmitted.

A sometimes cure, clean the rotor with 600 sand paper or finer, clean the pad surface completely. This works till you drive through the same mud puddle.

Correct cure. Turn the rotors; apply Brake Quiet to the back of new pads, following the directions.

Now even after you get more rust, sand, etc. on the rotor the sound is absorbed by the goop.


What does not work; Appling anything to the rotor surface. This just gets you killed when the brakes don't work.

add a case of beer and some ear plugs = noise is gone.

 

Or just turn the stereo up REAL LOUD.
That works good too.

HuH? I cannn'''tttt heeeaaarrr yooouuuu!!!!

 

Alright well I'll try some of the suggestions here this weekend and I'll post the results.
