Are there rotors for the Mach e select or premium that I can buy that aren’t going get that surface rust easily?

[TruWrecks]

Ceramic brakes work great, if you can keep them hot enough.

I used to use them on my track motorcycle after I trashed high carbon steel rotors after one day of use. They would warp under the heat cycling stresses. I switched to carbon ceramic rotors which solved the heat warping issues but they were trash if cold, and not useful on my street bikes for that reason. Those rotors required a couple hard laps with riding the brake lever a bit to bring them up to operating temperature. Once hot they were great. Change the pads twice per track day and have fun.

This conversation has just gone beyond my ability to compute. My mental asthma is getting fired up again.

He could be talking about the Carbon-Carbon brakes Link to Brembo 6 piston Carbon-Carbon Brakes

EDIT: Scratch that, they were Carbon-Ceramic.

I have a friend who is a part-owner of an IRL team. They get carbon-carbon brakes for their car. it's only about $50K to start and about $15K per race.

The surface rust is a result of the metallic brake pads depositing its material on the rotor and then rusting. My BMW was the same with OEM pads, and when switching the Ceramic pads, the rusting stopped. It obviously still rusts...but isn't the bright orange and red after a wash like it was.

I hear that if you put a light coat of oil on them, then they don’t rust as much.

This was a joke. Most people who read it will get it right away and LTAO. 1 in 1000 will think it’s a great idea, do it, and then drive off a cliff. Don’t apply a foreign substance to your brake rotors other than brake cleaner and, no, brake cleaner will not remove rust from your rotors.

You mean carbon ceramic. Those would be about $5-10K per pair if they even made them for the Mach-E. Which they don’t, because they’re meant for serious track use. Otherwise, rotors are iron and surface rust happens when they get wet. Use your friction brakes to magically wipe away the surface rust as stated above. Low dust pads will not correct surface rust on iron rotors.

I installed Racing Brake’s two piece aluminum/carbon ceramic rotors on my 500. At the time they were $12K for all four rotors including the pads. That was literally the best upgrade I’ve ever done on any vehicle. Not because they don’t rust and not because they don’t give off any brake dust whatsoever (those are big pluses) but because I dropped about 65 lbs in unsprung weight. It completely changed the steering, ride and to some degree the handing. Not to mention you can’t get them to overheat at least I haven’t been able to. Wish I had them on my RS when tracking that car.

At this time, Racing Brake isn’t developing any for the Mach-E but if they were to in the future, I’d be first in line.

I bet. $12K is reasonable for 4 CC rotors/pads considering what oems charge for the packages. Does your 500 have the CF track pack already? If so you’re way down in unsprung weight. Too bad there are no lightweight 305/315 meats out there?

Interesting question as I very rarely ever see anything that looks like rust on my rotors. It's been raining off and on for the last 2 days and they still look okay. Are you guys getting lots of rust forming on your rotors?

 

[Murse-In-Airy]

Yep. And I just “cleaned” these yesterday. No rain here. Been too cold for that.

 

[P. T. Magoo]

While going about 40, turn the gear knob to N, then push the brakes until you're going about 10. Then turn back to D, and repeat if needed.

Above is the best answer IMHO although it's easy to miss in this thread.

Often I would come out of work after after a heavy rainstorm and find all 4 rotors on my ICE mustang bright orange with rust. Within a mile of regular driving (several stop and go intersections), they'd all look just fine. In the ICE mustang no need to switch to neutral as Rick suggested, although I'd usually apply the clutch so as not to stall the engine. Switching to neutral in an EV is to discourage regenerative braking, as regenerative breaking keeps the pads and rotors from coming into contact.

20th century solution to a 21st century problem.

Easy-Peasy.

Also: “Wiping” rotors

I think that hummus on the rotors would act as a rust preventative. Would reduce stopping power, but smell GREAT!!!

Those rotors look normal to me. Is the backing plate rusting or is that just mud?

 

[bshaw]

I don't mind the rotors showing rust -- that is cleared by using the brakes as others have mentioned above.

But, there is often 48 hours between when I drive my MME. If I brought the car home during snow/rain, then 48 hours later the pads can be very stuck to the rotors and I have to break free to get moving. Is this because an EV keeps the pads pressed on the rotors vs. an ICE car that has the transmission in park?

I've seen mentions of this in other threads, but not a solution.
Would ceramic pads not meld with the rotors in the same way as the stock pads and therefore not stick after being parked for a long time wet?
