Hey guys
I'm a new 991s owner & I always end up with a rusty looking brake discs after I wash the car

Any thoughts ????

Cheers

 

Same here. But no big deal, disappears as soon as you drive off and apply them.

 

Unavoidable.

 

Is this your first car with disk brakes?

 

not technically, but you do have to give Porsche another $10k

it's one of my pet peeves about washing and detailing my cars. I haven't had the luxury of owning a car with carbon ceramics yet (I swore my next car was going to have it, but my build already cost too damn much this time

Like others said, let it dry and knock the rust off with a quick drive.
I usually wait a day or two after washing and then I take it up and down my driveway, YRMV, I have a large driveway.

Not sure if you're storing it for winter, if so, don't leave them rusty, take it for a quick spin so they don't rust all winter long

 

Griot's Garage makes a rust remover spray for rotors and such. Never tried it so no opinion on whether it works or not. I say for the price, try it.

 

Yes, unfortunately with steel breaks, this is what we have to deal with. Using a leaf blower or a master blaster will help, rather than letting the breaks air dry, especially in winter with cooler temps. I usually take a rag and wipe the discs the best I can before I drive because a lot of that orange rust will end up on your wheels in the form of dust, which is a bummer on a freshly washed car. This is one of the benefits to Carbon Ceramics. . . . No Rust, but pricey and overkill for most of us.

 

interesting, I'll have to check this out. Not sure how comfortable I am with spaying something one my brakes, but I'm sure it's safe, right?

 

I'd spray it on a rag and wipe. If it eats rust, it might eat something else too.

 

I'm assuming this is the stuff:

Doesn't mention using it on rotors, I'm not using it on my brakes, maybe I can try it on my neighbor's car first

 

I have the same issue

 

They are steel and will get surface rust when wet - after a few applications of the brakes that surface rust will go away - seriously - just drive her around the block a few times and that will be done(or get pccbs).

This has ALWAYS happened with disc brakes - its just that these days as compared to a decade or 30 years ago - the wheels/alloys are not solid and you can see the calipers now -

Progress aint pretty but it sure is effective :-)

 

Noooooo! Don't put anything on the rotors!!!! It's normal. If it bothers you wait until dry and drive around the neighborhood. It will come off

 

But therein lies the problem! It most definitely comes off over the course of the next day or two, and then you spend a hour or so re-cleaning the rust residue off the inner portion of the wheels.

I was so frustrated that I tried to figure out a way to keep the rotors dry during a wash. Got some magnetic vinyl sheeting and cut them to roughly the size and shape of the rotors. Actually worked fairly well in keeping the rotors dry, but over time they became a mess from all the brake dust. Honestly, if someone could come up with a product that would address this issue I think he could make a tidy sum.

 

This is going to happen all the time even if the car sits outside you will get some rust on the rotors. Like most stated once you drive they will come off.

If this really bothers you and you're ocd this will be a good quick temporary fix (we use this in the shop it's great for cars that we are delivering.)

We do have a product that we sell that will temporarily get rid of rusty rotors after a wash. however if it gets wet the rust will come back (due to the rain or another wash)

Take a look at the videos.
