Advice requested: How to keep rotors from rusting

Rotors: The large disc shaped things that spin

Calipers: The stationary things that squeeze the rotors to stop the car

You do not and can not paint the rotors. They will rust. They have to be how they are

Calipers can be painted. I would suggest sanding them down if they aren't too bad and getting a quality caliper paint kit.

If you look at the original post and the pictures provided, you will see the area of concern is the hub. His rotors, where the brake pad does it's work, are nice and clean. I think everyone who responded to this post understood what he was dealing with and trying to fix/prevent.


Additionally, the viper pics posted by Gary go even further to demonstrate this fact.
 
Holy smokes and thats a 2010 model? You'd think Honda would put in a bit more quality into their luxury brand....

cleaning off the rust, prepping and using caliper paint should do it.
 
The reality is that the metallurgy of production rotors, i.e. the bulk of OE supplied and most aftermarket rotors is so poor that surface rust should be the least of your worries.

And it's probably due to the fact that they are considered a consumable item. OEM rotors on most vehicles aren't even worth turning anymore.

Exactly. The days of quality rotors, when you could turn them 2-3 times before replacing them, is long gone. In most cases, it's simply a better value to just replace them these days.
 
A regular application of CorrosionX may help a lot. But may be more trouble than it's worth.
 
 
Serums Rustopper will do nothing for the OPs problem. The only real option is painting the area that already has the bad rusting. Rustopper is more of a preventative rather than a cure.

Perhaps, then, your review http://www.autogeekonline.net/forum/product-reviews/72026-review-hyde-s-serum-rustopper.html (as well as many others) was a fluke. :dunno:


This is my recommendation to the OP:

-Paint 'em with POR-15 Ceramic paint.

-Don't worry so much about painting along the fire-path...
First time you brake, the paint in that area will "burn-off".


-Next time the need for rotors arises try to opt for:
1. Zinc washed (Good)
2. Cadmium plated (Better)
3. $$$$ Carbon Ceramic $$$$ [Best (so far)...but: Ouch!!]

My review was focused on the face of the rotor and rust from washing, not the rust on the "hat" of the rotor, which the OP displayed in his example pictures. Two different things.

When there happens to be "rust" in the general area of vehicles braking system's components...
