Why do my brakes still squeal!!!

[Blown10thCobra]

So I did a brake job on my Cobra a little while back. First brake job the car has had since it was brand new, only had 30K on it, did it right after I bought it. Turned the stock rotors, and did it myself at my work so I know they were done right. Replaced the pads with some Hawk HPS pads, which I've used on my Supercharged Mini before and had no complaints. My brakes under normal light braking and when braking from backing up still squeal. Anyone have any thoughts??? Yes, I greased all the pins and moving parts of the calipers before putting things back together and cleaned all the calipers as well. It's about to drive me nuts!!!:??:

Mine are the same. I don't know what causes it, but it is a normal occurrence. Don't worry about it.

We did cross drilled and slotted rotors on the Mini when we did the brake job and I'm considering doing the same on the Cobra next time, I'm wondering if that would make any difference at all in the squeal? Probably not.

 

[ABrown]

I couldn't tell you. I'm on the same setup you are right now. I don't see it making a difference.

You've got the HPS pads? Do yours dust up bad? Because we've got the HPS on our Mini with literally like no dust at all, but the ones on the Cobra seem to dust up bad.

Same thing happened to me. I installed Cobra front brakes with HPS pads on my GT and now they squeak like crazy. Greased everything up and can't get the noise to go away for anything.

My Hawk HPS squeal when there cold. Had them a while now to.

I'm so tired of it now I'm willing to just scrap the money I spent on the HPS to get a pad that stops good but DOESNT squeal. Any suggestions????

My HPS pads on my 01 cobra squeekd with the stock solid rotors however, they did not make a single sound when I installed the CD/S rotors. Its just the price you pay for better stopping power... On the flip side, when they get up to temp they will stop making noise on the stock rotors.

 

[Blown10thCobra]

I was SOOOOO close to getting an aftermarket set of rotors, and I've about made up my mind I'm going to.

The cross drilled and slotted rotors werent bad at all, EXCEPT, (1)the slots in the rotor will sound like your being chased by locusts until the edges wear down and (2)your rims are gonna dust up bad depending on your driving habits.

We're running CD/S rotors on our Mini Cooper S and I ride an R1, I'm used to the sound and have learned to love it even.

*edit* Mind if I ask where you got your rotors from, who made um?

if the pads had those gay backing plate/shim things on them take them off,those make brakes squeak when they come loose. i did the brakes on my sebring not too long ago and about a week later the squeaked,i took the shims off and hasnt squeaked since.

 

[Blown10thCobra]

^They did.

So I put on my new stock replacement Brembo rotors last night and bedded the pads with them. All the squeak I had is gone. Mine squeaked constantly when I wasn't on the brakes, and even louder when I hit the brakes. Now there is nothing. I guess even after turning the old rotors, they were still a tad warped.

I still have the Hawk HPS pads in there and they make no noise at all, so that shouldn't be the problem.

 

[Blown10thCobra]

bedded the pads? You mean like breaking them in?

*edit* And warped shouldn't cause squeal, just wheel shake under braking
