I'll be painting my calipers here shortly and was trying to figure out if you guys know of anything that'll take rust off my rotors. Its not exactly on the rotor but rather on the ledge between the rotor and the wheel. I can take a pic of it tomorrow but most of you hopefully know what im talking about. They're brand new rotors so im kinda pissed they have rust on them already. any ideas guys? thanks.

 

its pretty normal.

 

I understand that. I just figured since I'll already be in there, might as well try?

 

take steel wool to it. i can't remember if brake cleaner takes it off or makes it rust

 

I'll try the steel wool. and i searched but couldnt find what i needed. whats a good product to use to clean the calipers. I have engine degreaser but that leaves behind a residue. thanks

 

try rust remover and steel brush?

 

they also make brake disk cleaner, I have a can in my garage

 

its gonna be a pain in the ass.

Once it is clean, it will probably get dirty really quick.

My rotors are disgusting..

 

just had my rotors done, i'll ask my mechanic what he used. Then again theyre resurfaced lol.

 

..could never believe that....

 

different shelf though

 

last i checked rotors were for stopping, not for looks. but seriously, its normal...anything you do, it will come back very soon. not worth the time to clean.

 

i may tackle this soon.. im going to do the rust remover and steel brush, and then use this primer stuff that covers it and prevents rust from coming back

 

or you could buy new rotors with some nickel cadmium coating and it will never look rusty ...btw that what I got when I replaced my rotors....

my 2cents

 

Ever change rotors in a drizzle? Laying flat on the ground, literally within minutes each raindrop will form a little rust spot. Bare metal rusts faster than you'd imagine.


As for rust paint on the edge of the rotor (I'm guessing that's what you're talking about?), put a wire brush on a drill then try POR 15.

The stuff uses moisture to cure, to the point where the company warns that even one drop of sweat dripping into the can will ruin the whole thing. The good thing about that is that it's recommended that you paint over rust rather than reduce it to bare metal. We use this on Jeep frames and tubs and I've personally seen them go 10 years on a 20 year old Jeep with no rust coming through.

The only issue I can think of to look into is how well it handles high temperatures. That, I have no idea. Well, that, and it gets expensive if you use a lot of it. Here it's about $50/quart.

I sanded mine forever before I painted em. You can try that.
