spyguy Posted March 15, 2010 Share Posted March 15, 2010 2 months ago, I purchased and installed 4 DBA 4000 rotors. They were beautiful, braking improved dramaticallys (ss lines, fluid and hawk pads). After a couple of weeks, I noticed a bit of rust on the discs, the outter lip, inside the slots, and the inner hat: http://img692.imageshack.us/img692/8282/img00594201003141734.jpg http://img371.imageshack.us/img371/3433/img00459201002141000.jpg http://img715.imageshack.us/img715/4506/img00461201002141001.jpg Does anyone else have this problem? Or am I being too anal about normal rust? it seems that this is beyond normal rusting. i've tried using a soft brush to clean the rotors as well, no help. it almost seems as if the protective paint coating is peeling off too. i've contacted fredbeansparts (where i purchased it from) to see if they can give me some insight. i'll keep you guys posted.

bigb3630123 Posted March 15, 2010 Share Posted March 15, 2010 I get a little rust if I let it sit through a rain shower but after one drive its pretty much all gone Link to comment Share on other sites More sharing options...
rao Posted March 15, 2010 Share Posted March 15, 2010 That is totally normal for uncoated rotors - it has absolutely no effect on their performance. It does show just how useless slots are though all those hot gasses that supposedly they provide space for apparently aren't enough to clean out the rust.

JoeFromPA Posted March 15, 2010 Share Posted March 15, 2010 Perfectly normal. Yes, you get uncoated rotors or you don't paint their hats, and that's what you get over time. I will say though that for fairly new rotors, those faces look awfully striated. Maybe it's just the Hawks. Link to comment Share on other sites More sharing options...
rao Posted March 15, 2010 Share Posted March 15, 2010 I have read that Hawks are excellent pads "confused" Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
SubyShop.com Posted March 15, 2010 Share Posted March 15, 2010 The salt made my rotors rust quickly too. It's only cosmetic. I think Centric hats have a more durable coating to prevent rust. I have a set of those handy to try after the DBA's are done. -Franz Link to comment Share on other sites More sharing options...
spyguy Posted March 15, 2010 Author Share Posted March 15, 2010 dont get me wrong, the braking is great with this break set up (I believe fredbeans calls it stage 2 - ss lines, fluid, dba4000 rotors and hawk hps pads). its just cosmetically, hurts to look at it, especially since the rest of the car is clean. has anyone tried painting their hats? is it possible?

rice_rocket Posted March 15, 2010 Share Posted March 15, 2010 I used to throw on some paint every now and again on my rotors.. no biggie.. it'll either peel for fall off eventually anyways.. just makes me feel happy for that little while I usually go for drilled "for show" since my slots always looked like crap because of it. The only time I had the slots was for my track car.. that burned up the rust in no time Link to comment Share on other sites More sharing options...
spyguy Posted March 15, 2010 Author Share Posted March 15, 2010 what type of paint did you use? also, did you spray the entire rotor and let some spirited driving take off the paint on the disc OR you used painters tape to tape off the area?

LegacyMUN2k6 Posted March 15, 2010 Share Posted March 15, 2010 You would think for the price you pay for these magical dba rotors, they would powder coat the vanes and hat. Link to comment Share on other sites More sharing options...
rao Posted March 15, 2010 Share Posted March 15, 2010 That would add too much unsprung mass. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
Mr. Sinister Posted March 15, 2010 Share Posted March 15, 2010 Cadmium/nickel plating would help to alleviate this problem. Link to comment Share on other sites More sharing options...
01rs25 Posted March 15, 2010 Share Posted March 15, 2010 Did you wipe these with brake clean when you installed them? Slammed more than your girlfriend. Link to comment Share on other sites More sharing options...

Tape off the rotor surface and make sure paint doesn't get into the cooling vanes. You could sand down the hat and use a high temperature paint on the hat. brake cleaner will break down the coating so be careful of that -Franz Link to comment Share on other sites More sharing options...
rice_rocket Posted March 15, 2010 Share Posted March 15, 2010 High temp paint, and I used a cardboard from the box it came in (had a hole perfectly sized for it). You DO NOT want to paint the front surface of the rotors!! it's going to mess up your pads etc I was told it doesn't matter what treatment is on the rotor, they all will eventually get worn off and rust just like the others... Premium just means better and thicker metal, the treatments will all wear off over time, although the premium will last longer because of the initial coat on the vanes and the edges of the rotor that see no real wear for a while.

N.sane Posted March 17, 2010 Share Posted March 17, 2010 Hot damn, i have the exact same rotors, installed since Apr 2009. I'll have to check mine tomorrow, too dark right now... Link to comment Share on other sites More sharing options...

LosAngelesLGT Posted March 17, 2010 Share Posted March 17, 2010 I live in Los Angeles where it simply does NOT rain. It is NOT humid. If I leave my LGT to sit for a week or two the rotors look like that. The OEM rotors did. The DBA4000 do. If you only did your front rotors, try taking off the rear wheel and looking at your oem rotors. I bet they have the same rust.

EDIT : this thread is a non issue I swapped all 4 to DBA4000. i agree, non issue, just an eye sore since its bright orange, and my rotas show a lot of hat of the rotor.

I agree completely but am not 100% on what to do about it long term other than not worry about it. Link to comment Share on other sites More sharing options...
N.sane Posted March 19, 2010 Share Posted March 19, 2010 So I checked mine out and I'm experiencing the same thing, but its less drastic than the amount you have Link to comment Share on other sites More sharing options...
