Squeaky Brakes

[79_maro]

So I've had this problem before, where my brakes would squeal when I pump the brakes and won't stop squealing until I stopped. I fixed it originally by putting disc brake quiet on, and it didn't squeak for a solid few months. I'm having this same problem again, where the brakes squeal loudly as I come to a stop, and don't stop squealing until I'm fully stopped. The brakes work fine, and are basically brand new, so I don't understand why they're doing that. Any helpful tips to stop the squeaking would be highly appreciated as I am really started to get sick of it. Granted, its a 1979 Camaro, so it is old, and I've been told that this is why its squeaking, but I don't agree 100%, and think there could be a solution to stop the squealing. Again, thanks for the help guys.

Your driving habits can glaze the rotors and pads causing noise. Using a quality synthetic grease on the caliper pins and the back of the pads will reduce noise too.

How much wear is on the pads? Some pads have a wear clip that squeals when you hit the brakes to indicate low pad line life.

The pads are only a year old, so there is hardly any wear, however I do tend to stop hard a lot because well I tend to drive fast in it and stop sooner than I should. I don’t think the pads need to be replaced, but if that’s the case, I will definitely do that. I’m just trying to come up with a solution to stop the terrible squeaking.

Semi-metallic pads are known for the squeal.

The goop you put on the backs of the pads helps but it needs to be redone now and then.

Ceramic pads are quiet but they hold a lot of heat and heavy braking followed by a dead stop can heat check the rotors. (Did that.)

I went back to semi-metallic pads and new rotors and just redo the goop when needed.

Believe it or not, I've been putting a light coat of anti sieze on the metal backing of the pads for a while now. We all know that stuff is impossible to get rid of, so it has been working great. A few hundred brake installs with no noise. I use synthetic grease on the sliders as others have suggested.

I think that most of the ideas have been covered by the answers you got. I find that if I get rid of semi-metallic brake pads and use organic pads, they don't squeal. Also, I put some anti-squeal on the back side of the pads before installation to get rid of vibrations that can cause squealing.
Everything I have with semi-metallic pads has a "groan" or "moan" when stopping or first releasing the brakes when cold. The organic pads don't make that noise.

I think you got a bad set of pads. I run semi-metallics on everything and never hear a noise. Ceramics don't seem to have the stopping power that I am used to. I do grease the pins and goop the back of the pads as a habit.

Me too, I started after I realized some OE companies supplied it with pads, like Honda.

Anti seize on metal to metal contact where the caliper comes in contact with the pad backing plate.

I do use synthetic caliper grease on slides

If you've turned the rotors, do you have a non-directional finish? Look at a new, quality rotor. They put a spinning grinding wheel against it to get that swirly look. This will keep the caliper from vibrating.
