That too, different rotors, different care instructions...

Please don't comment if you don't know wtf you're talking about.

Ceramic pads cut the dust to almost nothing on my 335.

I've had really good luck with ceramic pads. They don't have the same initial bite, but you get used to them really quickly.

Just take a second and search for the rotor problems related to using rim cleaners. I have no reason to make things up.

Simple Green and a soft brush works pretty well on BMW wheels and is kind to the environment. Waxing the wheels helps, but I'm curious; do you really need a special wheel wax??? I guess you do if you run with nitrogen in your tires...

If you have an accumulation of brake dust, consider Suzuki motorcycle cleaner. It's available in spray bottles at motorcycle shops. Leave it on the wheels for a bit but don't let it dry before rinsing. It is a highly concentrated soap requiring quite a bit of rinsing to get the bubbles (soap) off. As good as this stuff is for wheels and the engine bay, be careful; it will take the spots off a dog if you don't rinse thoroughly. From experience, I know it can leave barely visible perma-spots on BMW X5 running boards if not well rinsed.

Personally, I wash my wheels every time I wash the car and I wax them with leftover Zaino most of the time I wax the car. If you don't let the dust accumulate, it doesn't take long.

Pressure washer was my best investment ever. I line both cars up, pressure wash both wheels in <2 minutes then hand wash the bodies. If I do it weekly, I never have to touch the wheels.

Lets change the site name from bimmerfest.com to spellingbee.com

I DONT GIVE A **** who spells what they write incorrectly as long as i know what they mean. Stop being a hard on and correcting people for typos. LOSER!

LOL.. hopefully your Brakes dont Break then...
While I agree that spelling isnt very important as long as the meaning is translated correctly,sometimes peoples spelling and grammar are so poor that it is near impossible to figure out WTF they are attempting to say. When is enough ,enough?
Spelling has never been a stong skill of mine and I frequently went afoul of my teachers and professors with negative effect on my grades. People have it easy these days with computers with spell check. If a person knows that they dont spell very well or are prone to rambling, disjointed run on scentences it would be best to avail themselves of the technological assistance that is available to them. Point is that sometimes people dont know how in left field they are.

Anyway, Brake Dust is a fact of life. Clean as needed

Really?

(Please tell me your two spelling errors and lack of apostrophes was a joke.)

As someone who writes about cars for a living, I see "break" instead of "brake" all the time, even among those within the industry. Quite common.

As someone who "doesn't" write for a living..... I was only attempting to make the point that there is quite a bit of tolerance for poor writing out there already. If you read correctly, I AGREED that as long as the meaning is understandable, its not an issue. I told you spelling "aint" one of my strenghts
Guess MY meaning was at fault ??? HUH?
ps : if you see people within YOUR industry making the "quite common" error of Break and Brake.. THEY should be ashamed of themselves.....

Have always used P21S on my wheels, recommended by wheel makers and Porsche I believe. Works wonders and damage free.

Nobody said you need to know how to spell to be a good writer.

I'm on my second can of this stuff now...lasts about 2-3 weeks, depending on weather. It honestly does work just as good as it shows in the video. I have no idea how it works, but it takes a couple of seconds to apply to each wheel, and then absolutely nothing sticks to the wheel until it wears off.

I remove my wheels everyday for cleaning

Hi! Before I get torn apart, I've been doing this to my style 71's on my 2004 330ci since I bought it and the same for my 2012 x5. Mothers aluminum wheel cleaner spray it on dry and cool wheel, and let sit 1 minute NO LONGER rinse well. The oxalic acid is a weak acid that eats up the brake dust, it's the same ingredient thats in barkeepers friend you can get in a harware store mix with water spray on and make yourself for pennies.

I have the same problem, and can't stand dirty wheels. I just changed my brake pads and put the best ceramic pads. They do not make any dust at all. It's been 8 days and wheels are still pretty clean. Washing tomorrow.

But you decided to do it anyway, eh?

ard's been here a long time. He's a valuable source of advice. And an occasional source of entertainment. OTOH noobs have a habit of making a couple of posts (often with egregious spelling and/or grammatical mistakes), then disappearing.

Please, who gives a crap about what people think of my contributions?

It is one think to miss a spelling in a message (like 'think' versus 'thing')...but another to blithely misspell the title, AND THEN JUST NOT BOTHER TO CORRECT IT. I fully expected the OP to go 'OMG, let me go back and edit that'

And my comment about washing was not just snippy- why bother with changing pads? just wash the car and you'll save the $$$ and have the optimized breaking/pedal feel. All pads dust, some more some less. My Porsche, my BMW (both with stock and Stoptech pads), by F250, MDX, Infitniti, Dakota. Some look 'bad' after three days, some after a week...

I also suspect, but do not know, that 'pad wear' (and subsequent dusting) and rotor wear interact (ie the relative life of both parts)- is there a trade off? Do ceramics' dust less, but wear more rotor? Dunno. I just wash it.

Now, on the P car, I run track pads for track use and less aggressive pads for around town- but 'dusting' is not a criteria in my choices....

Because for the vast majority of BMW owners, it's easier to throw money at the problem rather than pick up a hose and a brush. I'm willing to bet you bleed your own brakes and swap out your own pads on the P car (I know I used to). But I bet the prospect of doing that would be too intimidating for most BMW owners.

PS Do they still make "dustless" (aka concours) pads? I remember instructing for one guy in a 930, whose pedal went straight to the floor entering Big Bend. You're right about your observation that harder pads wear rotors faster. But the 3rd part of the system is the fluid. Brake dust comes from the pads burning off as they turn kinetic energy into thermal energy. If the pads don't burn off, the heat gets transferred to the rotors ... and from there to the brake fluid ... and if the fluid boils, life can get really interesting, really quickly.

At least there was plenty of run-off room at Lime Rock (and I had spare underwear in my overnight bag). But boiling your fluid running a series of twisties (Tail of the Dragon, anyone?) could have much worse consequences.

Couple of misconceptions here....and I hope I spell everything correktly.
Semi metallic pads are harder than ceramic
Ceramic pads are cooler than semi metallic
Ceramic pads produce the same amount of dust but the dust is non-metallic, lighter in color and does not stick.
You would have to be an extremely sensitve or professional driver to notice the difference between ceramic and semi metallic pads.

There is not a rim cleaner that will damage rotors, period. The light etching that may occur with some stronger cleaners will disappear after the first block of driving.
