As you all know and have heard a million times, the brake dust on these cars is beyond comprehension. Worse than Porsche, Audi, etc. The OEM cinnamon textured dust has etched itself into my CSL wheels, to the point I nearly need a refinish after only 8 months. How BMW allows this to continue is one of life’s greatest mysteries.

Solution: European Auto Source lunch break brake pad swap to iSweep 1500.

The dust from the iSweep is a much more translucent color, rather than brown like OEM, about 90% less dust overall than OEM, and extremely easy to clean off.

On OEM pads, one trip to LA and back to OC (about 85 miles round trip) would turn my wheels full BRONZE looking, and require a full power wash scrub down.

Now on iSweep, I could probably do 4 or 5 trips of a similar duration, and still not have the horrific cinnamon bronze look.

Absolute game changer, and life enhancement. Worth every cent times 50000.

Photo with red mirror caps shows my wheels after 100 miles on OEM pads, to display the cinnamon bronze look, and the photo with Zandvoort mirror caps, and close up, shows the wheels after about 300 miles - pure black and looks nearly dust free.

Brake feel is exactly the same. No squeaking either.

This is a no brainer, must have mod.

I have the iSweep 2000 pads in my trunk right now, just been waiting for the right time to install. Glad to hear that the 1500 pads are working well so far. We've heard this is the best high performance / low dust street pad out right now for M cars!

So do the iSweep 1500 pads offer the exact same initial bite/grab as the stock pads?

So many times I’ve swapped to aftermarket pads and lost that nice bite the stockers had. Brake performance was always the same or better, but that bite was gone, which sucked.

Does EAS stock these, or did you have to order them?

I might consider this when I install my new wheels, but I really don't want to lose any braking performance.

I haven’t noticed any difference in performance or bite so far!

Yes they had these in stock, I emailed them to ask and to set up an appointment to come by for the install

Yes. Here's my official review from a couple nights ago. After having some little-d!*k-syndrome having redneck in his giant truck road rage on me & 4 other vehicles last night on the freeway, I can confirm the iS1500s stop as well (quick, hard, whatever) as oem. I had to slam on the brakes at 80 mph to avoid this a$$hole who cut me off and slammed on his brakes. The car stopped exceptionally well, allowing me to avoid slamming into the back of this jacka$$.

I have them in my M2 & my wife's X3MC. 6k mi on them in the M2 & 10k mi in the X3MC. I drive 500 mi round trip every weekend in the M2 & my wheels stay clean for weeks.

Your original review was what sold me on the isweep’s. I’ve been researching a pad solution for the dust insanity for about 7 months as the dust was destroying my experience with the car since it shows so horrifically bad on the flat black CSL wheels. I watched some reviews of a guy that put them on a Mercedes and didn’t have great results, so I paused the purchase and kept researching. If I would have know how well these pads work and kill the dust, I would have purchased these during week one of owning the car, regardless of cost. I would have flown to Africa to pick these up if I had to.

I trust you know what you're seeing, but it's been asserted that most brake dust come from the rotors, not the pads, so unless they have less friction I can't follow. Read second paragraph on the attached.

Interesting article, I have also heard this before. Whatever the case is, or combination of rotor + pad dust, with the isweep pads in place, the cinnamon brown dust issue from
OEM set up is absolutely gone now

How exactly does brake dust come from the rotor and not the pads that are obviously being worn down?

The rotors wear the brake pad material down. That's what the pads are designed to do. So, yes, the dust is CAUSED by the rotors, but it comes FROM the pads.

To be fair, I don't think that's what the attached PDF is suggesting.

The attached PDF is saying the dust comes from the iron rotors and that coating them prevented the problem.

I'm not saying that's true for our BMWs, but let's not mince words.

It is both. The rotor wears, otherwise they would last forever. Both carbon-ceramic brakes (SiC) and PSCB (tungsten carbide coated) produce very little dust and both have extremely hard rotors. The total surface area of the rotor is much greater than the pad, so 0.5mm of wear on the rotor is "worth" much more pad. The exact ratio is all over the place and I'm not sure what numbers to believe.
