What the hell is wrong with my brakes....i thought that part wasnt supposed to rust, not on an 04...

 

nah, that's a part that rusts on just about every single car ever produced (not just rx8s), unless it has a clear coat or is painted.

you can either see if you can get your dealer to paint it for you (some will) or paint it your self.

 

what kind of paint do i need to get, and how much is that gunna cost me

 

you can either get a high temperature brake paint kit like G2(~$35) or you can get some high temperature engine or grill paint ($3/can). make sure you clean really well, and if you are going to spraypaint it, mask it off really well.

the brake paints (like G2) say not to drive the car for 24 hours after applying the paint. the G2 kit comes with basically everything you will need. with the spraypaint cans you can either mask the hell out of the car to make sure there is no overspray issues, or you can spray some paint into a bowl or something and apply it with a brush.

on a previous car, i used a black glossy grill paint to paint my rotor hubs and calipers. i basically waited an hour for them to dry. lasted 3 years without fading or crackign/chipping.

 

hmm...sounds pretty sweet, i would need to take the brake off if i spray it though, right?

 

to paint the rotor hub, you might not need to take the caliper off, but i can't say for sure. i haven't painted my brakes on the rx8 yet, and i haven't paid that much attention to it. also, you might be able to paint the front side of the caliper without taking it off.

that said, you'll most likely be able to do a more thorough job and most likely have better results if you take the caliper off. but if you don't know what you're doing, brakes is a bad area to screw up on

 

my brother and i always worked on his t/a, and we also installed the brakes on it, so we should be able to

 

...i hope

 

Here's what your rotors should look like. These were painted with the G2 high-temp caliper paint, but you can use any high-temp paint. To paint the rotors you will probably have to at least swing the calipers out of the way. Make sure you sand the rusted areas to get the rust off before painting. You might want to paint the calipers while you're at it. There's a DIY thread on that in th DIY section of the forum.

 

Didn't you just buy this car a few weeks ago? If your car's still under warranty do what I did. Bitch bitch bitch at the dealer until they paint them under warranty. Took me awhile but got them to do it. The worst that could happen is they say no. Still worth trying though.

 

hmmm....not a bad idea actually....maybe i can get them to fix my scratch too!

 

Cool! Yeah I was dealing with a fairly new Service Manager so he was apprehensive at first. But when I persisted they finally painted them.

 

Just do a search on here. Snap-On posted the Mazda info that makes the dealer have to paint them for you. It is NOT a TSB, but if you take that info in, no problem to get them painted.

Your dealer will have to dig for this one. It is NOT a TSB. Have them do a ESI search with 2004/RX8/Brakes. It will post as an "MRI" (mazda repair information)

Rust can be seen on the brake rotor hub area when looking between the wheel spokes. The rust is most visible on vehicles equipped with 17" chrome wheels. 1. Remove rust from hub(s) by sanding. 2. Clean/prep hub surface for primer. 3. Mask off brake rotor area. 4. Apply primer around entire hub area. 5. Once primer dries, apply a heat type silver paint to the affected area to repair the vehicle. Note: Replace the rotor(s) only if the affected area cannot be repaired enough to satisfy the customer.
