Squeel from Front Brakes.

[wolverineottawa]

I did a 2g dual piston front brake swop on my 2005 Lancer Ralliart. A few minor fitment issues but in the end ll is well. I am using Hawk hps pads and cross drilled rotors with stoptech 600 brake fluid. The braking power is great no issues but when the brakes get hot the squeal quite a bit. I am wonder if any of you have the same issue?

How new is the set-up. It's probably just do to the coating on the rotors/pads. Check them over to make sure there is no debris in the brakes and apply silicone anti-squeal compound, there are a variety at o'reillys

Thanks car stopes MUCH better. I have cleaned it a few times and using high temp greese. My thoughts were after looking at the set up is the stock rotor is solid and the rotating mass of the rotors keep the pads away from contacting the disc. The cross drilled rotors have an effect???

Wow. I have no clue what you're trying to say.

Another thing that worries me is how you said something about high-temp grease in reply to the suggestion that you add a layer of anti-squeal. These are completely different things. The high-temp grease goes in the slider tubes (since you have floating calipers). The layer of anti-squeal goes between the backs of the pads and the shims.

That assumes, of course, that you have shims. If you don't, then the first thing to do is add some.

If the rotors are new they have a coating agent on them to prevent rusting get some brake cleaner and a rag and remove the rust inhibitor.

Did you miss the part where he says that the car stops well? That suggested to me, at least, that he's already been driving around for a while. So that coating is long gone.

Do you have brake shims? If not, get some, and use some copper anti-seize between them and the pad, as well as in the area where the piston contacts the shim. This has cured squealing with pads that for me were on the edge of being quiet.

Also, while I haven't personally confirmed this helps or not, you might want to put some antiseize on the pad edge where it contacts the caliper. Not the pad material, but the pad backing's edge. I follow this whenever I do pad swaps but yeah, never did a before and after to confirm this really does too much Sounds good in theory though.
