Brake squeaking

[Damian]

I'm trying to help a buddy of mine fix his brakes from squeaking horribly bad. He has the Evo 8 Brembos (front 4 piston calipers) with Hawk HPS pads. I've run HPS pads quite a few times and they neve squeaked this bad, not even close. You can hear his a block away!

So, he has brand new pads, rotors, and his calipers are rebuilt. We put some brake squeal stuff on the shims, the pad alignment pins, and the metal tensioner thing that goes on top of the pads. Everywhere there is metal to metal contact, we lubes it up. Did all of that, and still is bad. Any ideas to try?

Brembos squeak. Thats the breaks...

I've put Brembos on quite a few Eclipses and they never squealed like this.

Its possible that the brakes got hot enough at one point it warped the spindle. Now when he bolts down the calipers it slightly contorts it.

IIRC Hawk pads are noisy as shit at first and gradually quiet down. Not sure if spraying a bunch of crap on them was the best solution :huh:

The best brake squeal stuff is red and silicone based, stays slightly tacky and holds everything in place.

He has the red stuff, I forget what brand it is exactly. The sad part isthat his brakes only squeal on the drivers side. We've pulled that wheel off at least 10 times trying to figure it out.

I can tell him to change out the hub, but I don't think that's it to be honest. It does it off and on though. Doing a bunch of hard braking yesterday, it would do it once, then not the next time, then do it again, then not. That tells me something is loose but there are only 2 caliper bolts and the brake pad hardware that doesn't use any bolts. I even took the brake pad hardware off of my other Brembos and put them in there and that's when it started acting like this off and on stuff.

Maybe the caliper has a bad piston :huh:

We just rebuilt them and they looked perfectly fine.

The brembos on my Cobalt don't squeak at all... Watch, now they will sing like a canary cuz I said that.

Maybe there is a hard spot in the pad or something. If something is loose I'm pretty sure it would be constant under any braking condition... The fact that it goes away when you do some hard braking and then comes back after a bit but will go away again points my mind to the pad material needing to be warmed up a bit.

By the way, which pads did he get? Some hawks squeak way worse than others.
