So i just finished washing my car. And obviously the rotors did get wet. By the time i was done washing it and finished drying everything off the rotors naturally dried. and a layer of rust develops over them in a matter of minutes. This even happens after it rains. I go for a quick drive and the pads erase the rust. But can anything be done to prevent the rust from forming in the first place? im thinking like a type of spray or some easy method. Id like to avoid removing them to coating them with something.

Thanks

 

This is common and is normal. I wouldn't suggest that you use any kind of spray on them. The rotors will just heat up and evaporate whatever you spray on them. The rust that forms on the rotors will not do any harm if you are driving the car everyday.

 

ya but cmon, they make a shiny 2000 look like a 85 rust bucket. but i guess nothing can be done.

 

roll your car, one tire rotation while lightly pressing the brakes

or buy carbon ceramic rotors, I was quoted $800 for a pair, they were two piece and 13" tho

 

using them and keeping them dry will reduce the possibility of rusting.

 

Simplest solution = take off brake rotors, paint area not swept by pad with high temp paint...color of choice.

 

It's normal, if it bothers you just go for a 5 min drive after you wash the car and it should be fine until it gets wet again.

 

I use a small metal brush to clear off the rust, then use high temp. paint...U can do this by just removing rim/tire...just tape off/cover areas u dont want sprayd. I do this bout twice a year...gud luck.

 

or get zinc plated rotors.... mine don't rust at all.

 

Yeah, it is just good for couple of months (i guess depending from where you live).

 

i've had mine for a year now...no rusting

 

I had mine for almost 2 years. About a year ago and when i painted the caliper, I saw mine start rusting. and two months ago, i changed my brake pads. My rotors are getting worse.BTW, i live in new york.

 

yea my car only just saw water about 2-3 weeks ago....I don't wash my car often, It was probably like 3 months ago I washed it. Dirty car FTW

 

Just give it some time!!

 

 

Look where you live....of course they are not rusting.

I just put zinc plated on mine a week ago so they still look great. But i am expecting rust after the first ice when they salt the roads.

As for fixing the problem, you can paint the areas of the rotors that the pads dont touch. On my '99, i just used a brush very carefully with some rustoleum gloss black enamel, and it looked really sweet and held up pretty well for quite some time. I know duplicolor and G2 both make high temp epoxy paint specifically for brake calipers, so that stuff should do well for the rotors as well.

 

this is normal and nothing to get so concerned about. just drive it around the block after you're done washing it to remove the rust.

 

thanks....i think we've come to a conclusion on this thread.

 

Mine are zinc chromated and were rust free for 3.5 yrs and now rusted slightly! The solution for that isto clean and treat with a rust inhibitor!
