Angry Flash rust on rotors.

Ok, this irritates me. Every time after I wash my car, I see all four rotors have flash rust. What can I do to get rid of it? Paint it with clear rust resistant high temp paint?

See the build up around the rotor hats, the rotor surface that is not in contact with brake pads.



A better pic with ugly rust area I was referring to.

Don't wash your car, thats really the easy way. High temp paint on the rotor surface just outside the sweep area will get burned off

+1. I would personally just paint the hat and the rust-prone area and be done with it.

I only care about the surface where the brake pads don't make contact with the rotors, which is an 1/2" between the calipers and the rotor hats.

I just did a quick search and found this VHT Gloss Clear Caliper Paint, which should hold up to 900 degF. I will that a try.

Problem that plagues everyone... I've heard of zinc plated rotors (zinc oxide is white, doesn't look too bad) but that's about it. Problem is whatever you use to cover it up may just flake off - adhesion is difficult when this stuff is going through such wide temperature swings. Whatever you use to coat it has a different coefficient of thermal expansion compared to your rotors, therefore it is very likely to flake.

^You're not helpful.

Maybe I should put olive oil on the rotors.

Keeps my Alfa Romeo rotors nice and shiny, but for some reason it's really difficult to slow down or stop quickly.

Kuhan, what up man?

Your car is still one of my favorite. Do you have new pics?

I think you just wanted to show off your beautiful wheels and brakes. : P

Congrats on Rose winning the league MVP and GO HEAT... I think we'll seeing you guys in the Eastern Conference Finals.

I assume you will always have a little issue eith rust from rainy days an puddles, but when you wash your car you could always cover your wheels with a tarp or trash bag, and then come back and carefully clean your wheels after you've washed your car. That would probably at least lessen the issue

Also, badass wheel BBK combo, looks sexy and I'm sure you can feel the performance too! Your setup makes me jealous! ..... One day I'll hopefully join the sexy club *sigh*

^^ This.

I don't have that problem on any of our cars because the pads sweep the entire rotor surface. I think that's how a good kit should be designed, IMO.

Thank you for the kind words.

Thank you, thank you! Derrick Rose deserves it, imo. But the way the Bulls are playing right now, I'm worried meeting the Heat in the next round.

Yes, that's why I need to find a resolution.

Yes, I agree. I've seen Wilwood rotors and newer bbk rotors don't have the "flat" rotor surface like these Endless rotors.

Thanks for the compliment.

Here are a few pictures that I recently took this past weekend.

that rust will never come off, and has compromised the entire brake setup. i will gladly buy the garbage kit of of you for 100$

seriously tho nice car, post up results if you do use that clear.

Why not get proper sized pads

Pads aren't the problem. Swept area from the pads that fit in that rotor is the problem. In reality, it's the rotor that is too large for the caliper; it's a common thing so that there is more rotor volume to hold more heat, but this is the consequence.
