hey guys... a few months back i installed the hawk brake pads. i put them on... no noise... low brake dust... all was good... but the last month the front brakes have been making some noise while under long, easy braking.... jam on the brakes hard i have no noise... only under moderate braking... i talked to a buddy and we are trying to figure it out but i was wondering if anyone else here have had that same issue and what they have done to help it.

any help would be great.

I had the same problem I would come to a stop and breaking normally would cause a loud squealing noise and would have to really press on the brake to go away. Idk took a road trip to montauk last weekend ever since then it's been gone no noise. Weird

Dom,

I know I already told you this and showed you this product but Ill share again for any one else looking for a good easy solution. Mine squealed very badly when I first got them and I could not get them to go away. One of my good buddies who does most of my mechanic work on my jeep showed me this product and put it on my pads and never had them squeal again.

Here is the link to the CRC Brake Quiet Spray which is designed specifically for this problem.

If brake pads don't come with an adhesive paper to apply to the back of the pad, the product mentioned or something like it should always be used. The noise comes from the back of the pad rubbing of the piston if something causes the pad to vibrate. It could be something as common as dirt, which will sometimes disappear. Once you press hard on the pedal the added pressure stops the vibration.

Follow the instructions on the spray can. They often have a wait time between spraying the pads and reinstalling them.

Good luck.

There are also teflon or silicone rubber shims you can put behind the pads to help reduce vibration... the silicone rubber ones work better because of their nonlinear hysteresis, but neither is 100% guaranteed. Some use a high temperature brake specific silicone grease which tends to outlast sprays, particularly in combination with cushioning shims which tends to work better and last longer than either alone.

Some pad squeal is due to gassing, but that tends to be on high performance brakes being used heavily... drilling the pads, rotors, or even slotted rotors helps.

The only sure cure I've ever ran into is ear plugs.

Ordering this now to try. My Hawks have displayed this problem since I put them on - it drives me effing nuts. I don't hear it too much now with the windows up (it's hot as hell here) - but when the weather is nice I like to have everything open and the squealing SUCKS.

My favorite is when you just wash the rig. It's looking incredible! Turning heads...breaking necks....and then you have to stop Hahahahah ughhhhh

I'm glad I'm not the only one Dom. I've done everything I can think of and never have eliminated the squeal on mine. Backing the pads with some blue gunk did the best of keeping it down, but they still squeal.

I'm not sure what my next step will be - new rotors probably.
 
#23 ·
See I thought about doing that as well. But my only problem is that if I do get new rotors I would want the brembo drilled and slotted hahaha which aren't cheap. I'm probably just going back to brembo pads cause I know that didn't squeal and they were good! But hey as long as these things stop when I need them too I really can't complain.

After cutting or turning the rotors, the rotors need to be wash with warm water and soap to wash away the small metal particles. The warm water and soap break the magnetic effect of the turning. Otherwise these metal particles will be come embeded in the new pads creating noise. If one replaces the turned rotors then they will have to replace the pads as well.

What is the temp outside?

I noticed both last year (stock Brembos/pads) and now this year (new cross drilled rotors/hawk pads) below freezing I get a squeal until they get warmed... yesterday (drove 2 hours in salt spray/sub 20 degrees) - they were sounding rough... this morning (5 degrees) had some nice neighbor waking squeals leaving the sub.

hahah see with me the stockers never squealed or anything... only until i got the hawks did i get some squeal and its only when there is brake dust... first 3 days after a wash not a noise!!!! day 4 hits... cover your ears hahaha... im just going to go back to brembos and see what happens... atleast if they still squeal after that i can take it to the dealership and possibly get new rotors from them... who knows

It looks like I have been one of the unlucky ones to get the annoying squeal twice. I had Hawk ceramics on the front and rear of my 14' and they started to make noise after a while. I then tried the hawk ceramics on the front and stop techs on the rear of my 15' and they make noise as well. It is so annoying! I'm now getting ready to order brembo cross drilled rotors for the front and rear and a new set of hawks and see what happens. Anybody find a solution that stops the squeal other than going back to stock pads?

Great solution...put a s/c on it, blow a hole through the block. Look at it sitting in the garage - no squeal! :lol:

J/K! I replaced my Hawks twice, different pastes on the pad backs, sanded the rotors, lightly turned the rotors, etc. - they always squealed when it was over 75* outside under light pedal pressure. I never tried to change the rotors, but I've heard good results from the Brembo replacements. Good luck!

Currently suffering the ""squeal" again.

9K miles on new rotors and (stock) pads.

Squealing horribly on *every* stop in local/city driving.

Had it in at the dealer last week. Service advisers response to my complaint: "dirt on the brakes, or the cold weather". Yeah, okay :rolleyes::rolleyes:
