Brake dust

Ok so I knew it was going to be bad but it's worse. I powdered coated my wheels yellow and the brake dust is insane. Anyone using ceramic pads?

Brake dust

I've looked into it a bit and it seems that it's not good for tracking so does that mean they are not as efficient?

The stock brakes are amazing as is - there are a few upgrades in grip - I am not sure about ones for less dust. I went black mainly because it looked right with my red - and secondly because of the dust

I got to where I sorta like brake dust. Makes her look used like she was made for. As long as the wheels aren't too complex and are easy to wipe down. The Lotus Sports are great. (New silver set on the water now!)

Brake dust

Even with the anthracite wheels, the brake dust drives me crazy. Compared to the rims, the dust looks brown, so it still shows.

You can put in ceramic brake pads and the dust will lessen. But you will have to put the brake pedal through the floor to stop your car.

This is the trade off. Less braking power = less friction = less dust.

If you never track your car, you'll be happier with ceramic pads after you get used to how ****ty they are at actually stopping your car.

Otherwise, my only other advice is to take your wheels off every couple of weeks and give them a good washing.

And, ceramic pads are tougher on your rotors; you will be replacing them more frequently.

Erm, you may be confusing the ceramic pads I'm talking about with some other kind of ceramic pad.

Brake dust is 90% rotor material.* So by definition, if you have a brake pad that produces less dust, you also have less rotor wear.

* - I got this information from a Brembo brake engineer who told me he knows this because they've run thousands of hours of tests and this is what brake dust is actually made of. It sticks to your wheels because of the static electricity caused by dissimilar materials rubbing against each other.

That's a cool experiment. Someone took it a step further and made a caliper cover full of magnets to try to capture brake dust. I have no idea how well it works, but it didn't do anything to improve their spelling. Break Dust Terminator - Suck It Up - Grimetech

I did a Google search real quick and found a whitepaper from EBC Brakes concerning brake dust as a direct function of rotor wear. Their article corroborates what the Brembo engineer told me.

Being old school, I just keep my wheels waxed so less dust sticks.

So, with all these little piles of dust on my wheels.....how long are the stock pads going to last me? (normal non-track town driving). Seems like they are going fast considering the dust volume.

At least 20,000 miles, according to other posts that I've seen. I'm at 18k now, and still on the original set. So, not to worry.

Brake dust covered wheels doesn't affect performance does it? If not, what's the problem?

I actually wanted dark rims so I guess it worked out for me haha

I found that Armour All Wheel Protectant does an awesome job. My wheels had >1/32" of an inch after 2 weeks with my race pads on the street (pads wore down more than 2mm). I cleaned them up and sprayed them with the Armour All wheel protectant... NO more dust at all! You could see a small area that must have had a small pool of water when I sprayed, that area had a pile of brake dust. It's magical!

I like the ceramic pads from Hawk, but supposedly not good for track. And frt only IIRC. Speaking Elise here, not Evora.

To easily & safely remove brake dust, I use P21S wheel cleaner.

Harder jobs: P21S GEL works well, as you can leave it on for a while.

I wax the wheels with my favorite car was: 1 Grand Blitz Wax. MUCH easier to clean.

My guru in these matters:
