They do make special wheel cleaner that helps the dust not stick your wheels as much but if you are running stock pads you are running some of the dustiest pads out there. There are pads that make almost no dust (like our Magic Pads) which makes keeping your wheels clean a much less daunting task.

No but it sucks to always have to clean your wheels and it can hurt you in the long run if you never service or clean your brakes. Brake dust can actually accumulate inside the caliper and due to the heat generate by your brakes can turn into a very hard clay like material that can etch your rotors, cause squeaking, and damaged the finish on your calipers.

This is off an EVO we just worked on that has very neglected brakes. Car has 45k on it and its looks like its never been cleaned. As you can see brake dust in small amounts is harmless but if left unchecked can lead to some pretty big headaches.

Normal:


Major Deposit:



Nasty:



This gets into the caliper between the pads and piston everywhere were dust can accumulate.

+1, I had so much gunk in mine after a few track days that they were making the pads stick and retract crooked (as far as I can tell, because after I scrubbed them they don't drag anymore)

may it affect the S-AWD ?

Hi Guys !
I have a good question for all of you.

As you know, the car has a super-all wheel drive control. It's a intelligent control car. The car will control brakes, during hard braking (ABS) or turning fast (only the side you are turning in this case).

BUT, if you change the pad's brakes, it'll change the way its going to brake. If you have high performance brake, I guess it will brake more than it's supposed to. Don't you think the car may lose good ABS braking because it brakes too hard (on snow, dust) and may over turn during fast cornering ???

I'm looking for low dust pads but I don't trust it very well.

What is your experience about it ?

that's true, but i must admit those oem pads are very, very dusty. i thought axxis pads were dusty, but them oem pads are ridiculous.

hm, after searching a bit, i noticed most aftermarket pad makers only make front pair and not rear pair. anyone know why? it's not about the S-AWC thing is it?

No just because the rear is a new pad shape for Brembo and it takes a while to get the backing plate. Satisfied has rear pads available already as they actually produce their own backing plates. Their carbon ceramic pads hardly dust at all and work awesome!

I think the large amount of brake dust is from the material the rotors are made from. I haven't seen any other car's rotors get surface rust this quick. After I wash, before I get the car all the way dry, my rotors are turning a slight gold color.

I took off all 4 rims and waxed them. They still get dirty, but it takes very little effort to clean. Just using a pressure washer gets most of the crap off the rims. Of course this won't help with the other parts, but the rims look better.

Its not the rotors that make dust its the pads and the reason your rotors change color after a was is because of the pad material that's on the rotor. You don't usually see lots of brake dust on most other cars because they aren't running the same pads. EVO, 350z, STi, Corvette etc have higher performance pads and brake systems then a Ford Torus and the dusting is because the pads is producing more friction but wares out faster. Much like the eraser on a pencil. Crappy pencils have hard erasers and don't work very well but last forever where as a nice art pencil will have a soft eraser that works great but wares out quickly.

When you get a new pad the pad will transfer a layer of material onto the rotor so it can generate friction faster. Also the yaw control uses a magnetic trigger wheel in the hub to sense how fast each wheel is traveling and then the yaw controls start to take over it uses these triggers to decide how much to slow down each wheel to assist you. Putting hotter pads in your car will effect this slightly but the system knows when to turn off the control once it reaches the desired force, it just gets there faster. The ABS will still be able to keep your wheels from locking no matter how hot the pads. The only way you can really mess up the yaw is by changing the brake bias by putting a hot pad in the front and not in the rear or increasing the piston sizing of your calipers in the front and not the rear.

here is another opinion from another post : "If you replace the rear pads, it will affect the S-AWC engagement of the rear brakes to stabilize the car. With an more aggressive pad it might apply more braking power than usual to stabilize and cause the car to lock up the rear wheels...

but i'd like to understand what you mean by ... you can really mess up the yaw by changing the brake bias by putting a hot pad in the front and not in the rear.... do you mean that if I change only front pads I'm going to affect the yaw (what you mean by bias ?)

sorry for stupid question !!
thanks for answer

This thread is making me think about changing my pads now. It would be great to not have a layer of dust after driving less than 15mi.
