I've got a brake question. The car is stopping fine, and under normal conditions nothing is unusual. However, after hard cornering and/or hard braking, or occasionally just after 20 minutes or more of driving, I start getting a noise from the brakes. I believe it is only the front right, but it is hard to tell since it only happens when moving. The noise is a scraping noise like one of the pads is scraping the rotors without the brakes engaged.

Unlike the normal "pads are gone, replace your pads n00b" problem, the sound stops when I actually start to apply the brakes. I also took the wheels off and checked the pads, and although they are starting to get low, they're nowhere near gone, still about 1/3rd there.

Also, if I don't drive for a couple hours then starting driving again, it goes away.

I just had the brake fluid flushed and replaced along with some other work at the Honda dealership.

Thoughts?

Thanks

sounds like the caliper might be sticking a little. pad is touching the rotor a bit, creating heat, which expands the parts causing more friction and makes the noise audible.

there's only one way to fix it...

comptech is out of business fool

for a couple months now too

just get Brembo's

oh shit!

damn, i'd thought about SCing another S2000 one of these days. I guess you could go Vortech, but it's not as good.

hawk pads, stock rotors/calipers, and super blue fluid ftw. no one on here is driving hard enough or fast enough to "need" big brakes.

4/18/2007 11:32:37 AM

yeah, i agree. i was just kidding.

i had big 4-pistol Wilwoods on the front of my Miata (and 2nd gen Miata brakes on the rear), and didn't find them to be particularly noteworthy (although maybe in that example, 1st gen Miata brakes would've been inadequate...but they certainly didn't have anything over, say, stock S2000 brakes).

yep. in alot of cases, a drilled/slotted rotor isn't any better than a solid/vented one due to the loss in surface area.

with bigger calipers, you've got the issue of harnessing that braking power. if you;re just locking them up at the same time as stockers, what's the point.

I really don't think anyone here is driving hard enough on the street to warrant super blue, either

I think I still have a cup of super blue sitting on my table in the garage. I think it's yours, Callahan.

Thats kindof what I was thinking...any advice on what I could do to resolve it? I'm a n00b when it comes to brakes (and most car stuff, but brakes especially).

Also exactly right...even the race S2000's tend to go with the stock rotors/calipers...they're plenty heavy duty for any normal tire. I'm not running Hawk Pads yet (have a set to put on when the current pads wear out), but they're an equivalent brand that I've gone blank on the name of (squeaky but awesome stopping power). I was running Super Blue because I was getting fade with the stock fluid, but I've heard it picks up a lot of water and you need to change it often, so I just went back to stock fluid for now. Sure enough, the brake feel improved a lot...I'll probably swap back to Super Blue later this summer. It was definitely a lot better after repeated Dragon runs and such.

yeah, by nature any brake fluid attracts moisture bad. i have also heard super blue is worse, but i don't know if it's actually true. if you're serious enough about your braking to run it, you're going to be bleeding/flushing your system enough it won't matter anyway.

as for the caliper, if that is indeed what it is, you can rebuild it (assuming they make a kit for those calipers, i don't know). you don't absolutely have to, but i would reccomend doing the other side also. if they don't make a kit, your only option is new calipers.

you might be able to free it by taking it off and running the piston in/out a few times, but usually not.

get ATE type200 instead of superblue. same stuff but w/o the annoying as shit blue dye.

however, i'm skeptical that its needed on a street car.

rebuild the caliper, give 'er a flush w/ new stock fluid and call it a day

Haha, what a crappy night. Thanks again for the help. What's new w/ you?

Tell us about your luck w/ rebuilt calipers

4/18/2007 12:52:09 PM

rebuilding them is easy. its getting all the damn air out thats the hard part.
