OK, so I have a nice set of Ceramic breaks, new calipers, rotors, etc... I've been having an annoying squeak from the front drivers side and I thought it was gonna get fixed when I got a few other things looked at on my car. We replaced the broken brake clips on it, and there were a few minor other things to do with the brakes, but it still happens. This squeak isn't when I apply the brakes, but rather, it happens when I'm driving, and it goes away when I brake. It's also somewhat intermitent. It still happens 75% of the time, but the other 25% of the time, it won't happen again until I come to a complete stop and then start again. I know that nothing is locked, all the fluid is topped up, and everything to do with the breaks is 100% - now I've been told that there may be a lip of buildup on them and that they might need to be grinded a bit as well as the rotors, but I was not sure if you guys were aware of any other problems that may cause this. Also, how much of an advantage would I get if I went to the nicer brake lines (I think they were the braided ones).

That happened to me too.

Check the stome shield behind the rotors. Mine had bent a little and was just touching the rotor and at time could sound pretty wicked. I just bent it back out but ever once in a while it will start back up again. I need to just take them off. Give this a shot and let me know what happens.

About the stainless brake lines - they would look sweet but I don't think that you would notice and difference at all.

The difference between rubber and SS lines is day and night. There are tons of posts on FEOA talking about the benefits of buying them.

Thats fine - I think it you would be farther ahead to go with a bigger rotor that a stainless line. Big rotors are like a breaker bar on a wrench - gets the job way more efficientley and applies more power - the friction point of the pad on the rotor has a larger radius from the center axis of the wheel. I know there would be some difference but I can't imagine that much pressure loss/fade from a standard line.

Do you have SS lines on your car?? What differences did you notice. I'm curious. If it is a big difference I will put them on when I do a big brake swap.

One of my buddies (actually 3 of them now) with ZX2's. Put on SS lines last year....ALL of them notice the brake grab a lot sooner....and they also grab harder when they need it.
I know one guy swears that they saved his life last fall when he dodged a Civic (I think?) that ran a red light.

Did you resurface or replace the rotors? A very common mistake when brake work is done,is not to resurface or replace rotors. Even if you didn't feel your brakes pulsating with your old pads,you should do so. You will alwayshave some degree of runout on your rotors that COULD lead to that annoying(chirp,chirp,chirp,chirp) when your foot is off the brake pedal. Also make sure your caliper slide pins are nice and loose. That can also contribute to noise. And third make sure there is nothing between the hub and your rotor,where your rotor could be sitting "crooked"on the hub.

As previously mentioned, first check the useless, rusty shield on the inside of the rotors. Just remove them - the do nothing but cause trouble eventually. I've run really bad rotors in the past with really degraded sleeve pins and never had any squeaking sounds. Bad pins/rotors will show up as brake pedal vibrations or uneven pad wear - and I have seen plenty of that.

So have I.I do this for a living.I can affirm that stuck slider pins can also contribute to noise.A rotor with a small degree of runout,running with new pads, on a caliper that has seized pins,can glaze out that small portion of the rotor and create that annoying chirp while your driving and dissapears the moment you touch the brake.

by any chance does it sound like a school bus when you try to stop?If it is you have a seized brake caliper.When I did my rear disc brake swap I got a faulty caliper and it sounded like a school bus was trying to stop.

Or, to paraphrase, If it sounds like 60 screaming 7 year olds, It could be a stuck caliper :lol: :lol:

Thanks for the help guys, getting the rotors resurfaced, and I'm gonna see about that stone shield. As for the screaming kids and such, no, I had mentioned that it went away with stopping, but thanks for the help there too! If I do ever find that happening to my car, I'll check that out!

New caliper can sometimes come already seized or with some defect so don't eliminate that as a possibility until you really check them out. This is great. Swigger is relly giving Sirigan a run for his money. And High, We are all waiting for you to get an avatar lol. : )

I know that they can come already seized, but the sound is NOT when breaking, it goes away during breaking.... it happens upon just normal driving or acceleration AFTER breaking. Could that still be seized if it doesn't happen during breaking???

only hear it when driving, it stops the second that the brakes are touched, as long as the brakes are on it makes no noises whether stopped or stopping. And yes, I hear it when driving, at a high enough speed, I'm not sure whether it drowns it out (my tires are fairly loud) or whether it just stops at the high speeds, but you can definetly hear it at the low speeds most of the time.

It seems to be happening less and less, but still sometimes, as for the wear, it's even wear, and only about 4 month old pads. Still haven't got the time or the money to get the rotors resurfaced. It actually seems to only be happening in the rain now, or on humid/damp days.... I'm gettin really confused. It doesn't seem the be anything serious, so I'm just gonna leave it. My front shocks are dead though so it looks like I've gotta save for my GC coils and toiko struts.

get new brake fluid, bleed them 2x, drive for about 2 miles with the brakes depresed. this will "cut" whatever is on the pad off thats making it make that sound. this is typical of of new brakes and rotors.
