How could I cover up the rust on the base of the brake rotor? I'd like to remove it permanently but covering up is just as good.

I was thinking some high temp paint, black would look pretty mellow behind the rim.

 

yes, how do you?

 

sand it down with sandpaper (start coarse, then go to fine). a better long term solution would be to buy stainless steel rotors or hubs.

 

just sand it down like dFreezy was saying.....then i'd paint it w/high temp paint to keep it from comin back....thats what i was plannin on doing when i do my brakes again, painting them silver/cast iron color....i have 2 sets of honda rotors that i switch out when i do my brakes...... they rust too
to rust!

 

Don't use sandpaper, it will cause a chemical reaction that could lead to 'pitting' of the rotor. Use garnet paper instead (can be found in the sandpaper section of the hardware store).

can you elaborate a little more? i've never heard of this

 

This is from Stoptech, and it is talking about uneven deposits of pad material, but the same thing is true of rust:

"vigorous scrubbing with garnet paper may remove the deposit. As many deposits are not visible, scrub the entire friction surfaces thoroughly. Do not use regular sand paper or emery cloth as the aluminum oxide abrasive material will permeate the cast iron surface and make the condition worse. Do not bead blast or sand blast the discs for the same reason"

 

interesting....i havent heard of this before! so, are you suggesting that even on the surface where the pad doesnt have contact then?

 

Well, if there is rust on the hub or on the edges of the rotors, I guess you could use sandpaper since it isn't the actual friction surface, but then you would still need garnet paper to get the rust off of the rotor's polished cast iron surface. Garnet paper is identical to sandpaper, except in terms of the materials it's made of - looks the same and is sold in the same section.

 

if its on the surface... u have to get it resurfaced with a brake lathe. if its just the edges, sand paper would do fine.

That's an option if the rust is really bad, you might want to get them turned or just buy new rotors - they are only like $20 each at Autozone.
