Car is fully washed and detailed, what about the rusted brake rotors?

**Don R** · 12-13-2018, 02:47 PM

Im wondering how some people deal the brake rotors rust after its been washed. The only thing I have come up with is drive the car very slowly with foot on brake a very short distance and the rust dust isnt too bad on the wheel. If I get in car and drive normal speed to the first stop I make it will have a nice coat of rust on the wheels.

I generally do something similar to you. I drive my car up and down my driveway slowly and work the brake slowly till I do not hear that *sheering* sound anymore.
Some people like to use a rust stopper product like Hyde`s Serum Rust Stopper which you spray on the rotor, brakes and it helps stops the rust build up from occurring.

Do you know if that affects a coating like Gyeon Rim that I have on my wheels?

It is ph neutral and acid free so it should not cause any issues with the coating.

I never worried about that because I consider it trivial.

The surface rust on my rotors is sometimes too serious to be dismissed as trivial; it literally ruined the S8`s rotors one time when I figured it`d be no big deal to just let it go

I do the "drive it a little". Then I use a RW to reclean the wheels.

I thought the Hydes would be great, but IME it`s merely so-so. And, while it might be a complete coincidence (yeah, right

), after I used it on the A8 the last time, getting some on the calipers, I had to get the calipers refinished as their oe finish suddenly went bad. I`d used it before without issues (other than its mediocre performance), but that time it cost me a bundle and now I`m leery of using it again.

Thanks for the comment. It was great input. If its so trivial why even bother to read post and then take time to make a worthless comment?

When I spend time and money doing something like cleaning my wheels I like some pay back. That pay back is they look good for a little while.

Don R- FWIW, RTexasF might`ve come across more, uhm..dismissive..than intended. He`s not the kind of guy who trolls a thread just to tell somebody their concerns aren`t valid.

It seems that the severity of this issue varies greatly, from "what?!? no big deal.." to my "what do you mean I need new rotors?!?".

You might want to try RWing the wheels after a spin around the block (with some good, hard braking included). I worried about scratching their finish or something, but that`s never actually been a problem. The light coating of rust cleans off quite easily as long as the wheels are LSPed, and easily enough IMO when they`re not.

Just be a little careful about getting the RW on the rotors, I was *astounded* when having IUDJ on the swept surfaces resulted in a "holy [cow]!" moment when I first applied the brakes, man that stuff sure make `em slick, never woulda thunk it. That one hard stop did cut right through it, but two gentle stops before that did not.

Since I have 3 coats of Gyeon Rim on my wheels and calipers I think I will stick with the pull out of driveway and and drive real slow with foot on brake to wipe rotors clean.
I dont want anything eating away the ceramic coating on the wheels

Hydes won`t do anything to Gyeon Rim. You will be fine if you decide to use it.

Don R- I bet the coating will hold up fine if you do that quickie rinseless wash of the wheels after driving it around the block/etc. It sure doesn`t compromise the LSPs I use on wheels, let alone the coatings I`ve tried.

Even just going up/down the driveway might be enough for the pads to wipe the rotors clean, and once that`s happened you can clean off the rust-dust easily enough since it`s not as tenacious as brakedust. Well...easily enough for something we`d all rather not have to do in the first place!

This has become a standard part of every wash for me. If the weather`s too bad I`ll move the car around in the shop, but that isn`t really very effective even though I have pretty much room.

I wish I could shake the idea that the Hyde`s messed up the finish of the A8`s calipers...just *too* coincidental, I could almost watch it happen...every place the old oe finish was a little compromised (and had been OK like that for years) looked *awful* after that use of the Hyde`s, cost me a [freakin`] fortune to have all four redone properly.
