Been running my front Brembro blanks with Hawk HPS pads setup for over 2 1/2 years and have had pretty persistent break squeal, but it doesn't happen when I brake lightly or heavily, only moderately.  I had my mechanic cake some messy red anti-squeal goo behind the pads before the winter rolled in, and it helped for like 2 months before the noise came back again.  Anyone have any recommendations on another tactic to use?  My mechanic suggested that the "metal parts" on the calipers that the pads slide into can eventually wear down and cause rubbing and squealing, but I know nothing about this.  Maybe order new "metal parts" (can't remember the official name... shims?), or just blame it on it being an afermarket, noisy setup?  Help.

I blame it on the Hawk pads. I have the saem setup, and I get the occasional squeek. I blame it to the Hawk pads emitting off a lot of brake dust. First, I would put anti seize behind the pads. Second, I would lube the slide pins. I plan on resurfacing my rotors and deburring my pads to maybe help with the squeek. If all else fails, I'm getting new pads. I hate the squeek, and it annoys the crap out of me. The hardware itself will not cause your brakes to squeek. They are there to help the brake pads slide, and to keep it stationary.

+1 on the Hawk pads.  I had the same squeal with my Hawk pads.

I've been running the hawk pads front and rear for a year + and don't have this issue at all.

So it might possibly just be the composition of the pads... greeatttt.


Thanks for the tips Thien.  So do you mean put more of the anti-squeal behind the pads (exactly what my mechanic did but it only helped for two months), or actual grey anti-seize that you'd typically use for bolt threads and stuff?  I might need to have my rotors rotated or resurfaced as well, as I'm getting some shudder again.  How do you "debur" pads exactly?

I usually put the grey anti "seize". It works great, and I use it on all the cars I work on. I rarely have comebacks when doing that. If you are getting a shudder, I highly suggest resurfacing them if there is room to resurface. As for deburring the pads, I usually just use the flat part of a concrete floor and just put a little force and rub the pad back and forth.

I have used that red shit that is for brakes, it has worked since I did my GS caliper and Coupe bracket/rotor upgrade, which is like 6+ months now.  they just started to sqweek (htf do you spell that?!) again.  I am going to him them with some brake cleaner and re-apply the red schtuff.

Thien, any particular brand anti-sieze?

No particular brand. All anti seize are the same.

Thanks for all the info Thien.  I shouldn't have a problem resurfacing the rotors if they really need it since they've never been resurfaced before.

I think pepboys does it for 10-15 $

Pep Boys... "does everything for less" lol.

When I cleaned up my brakes and wheel wells last week, I used some brake cleaner on the brake components, and the squeal stopped for like... 15 miles, then came back.  Joy.

Did you use brake cleaner on the rotors and pads? If so, thats why. Do not use brake cleaner on rotors or pads.

That's so confusing.

yeah, why not Thien?  I was going to do that this weekend...

Yeh, wth?  If you can't use brake cleaner on rotors and stuff, than what CAN you use it on??  I didn't even let the stuff dry; everything got washed with soap and water at the same time.

You are suppose to use hot soapy water to clean rotors. You can use brake cleaner on new rotors to get the oil film off. Afterwards, you are suppose to use hot soapy water. Brake cleaner evaporates very quickly and what it does is magentize metal particles together. This will cause rotors to squeek from time to time.

Interesting.  My rotors have squeaked well before ever using brake cleaner on them, however.  I guess I did this partially correct though, because I used soapy water on them... the water just wasn't hot lol.

did brake pad check before it went for inspection. put that spray on disk quiet stuff on, so far after week no squeaking. shims deff help. my friend put some kinda grease on rear pads and they didnt sweack, i think great works better then spray on stuff

Do you spray the disc quiet stuff right on the rotors?

no, you should never spray those
i sprayed it on back of pad where it contacts caliper and calipers themself where it contacts the pad, i did spray under shims as well

That's what I thought... just wanted to make sure.
