After this very short "disclaimer", he procedes to only expound upon the shedding of brake pad material topic.

Hehe, and Neil Armstrong never "sold" Duralube.

OK, I'm not arguing the issue of brake pad material causing pedal pulsation. I just don't want people to dismiss rotor warpage as a result of improper rim mounting and since the original poster has indicated this didn't happen in his case, I'm stepping off this bus at this stop.

Carry on.

And, I'm not sure if that article is actually a Stoptech sourced one, unless Carroll Smith works for them, but Smith is well known for his books on race car engineering.

Carroll Smith no longer works for anyone. He died in 2003.

His books on race car engineering are indeed excellent.

When I look at an S2000 front rotor, I just don't think it will "warp". The internal vanes just make it too stiff of a structure.

I met Mr. Smith in 1999. Carroll Smith along with Carroll Shelby played a major role in Ford's success at Le Man's in the 60's. He was a cool dude.

The sentence after the one you quoted:

" They are also subject to frothing from high frequency vibration, which gives a soft pedal. Soft brake pedals may be OK in non-high performance cars (in fact, most drivers accept mushy brake pedals as normal) but they are not acceptable in any situation where the driver intends to modulate braking at high force values."

I don't think he's recommending using DOT 5 fluid ...

I don;t think he is reccomending DOT5 either, but I also don't think he is discouraging it enough either. An example of "modulate braking at high force" would be anytime you kick in ABS. DOT5 fluid is completely incompatible with any car equiped with ABS (Like the S2000, and virtualy every other passenger car on the road made within the last 10 years.)

DOT 5 fluids are silicon based and are non-hygroscopic, which is good. They are also subject to frothing from high frequency vibration, which gives a soft pedal. Soft brake pedals may be OK in non-high performance cars (in fact, most drivers accept mushy brake pedals as normal) but they are not acceptable in any situation where the driver intends to modulate braking at high force values.

Carroll is in no way recommending DOT 5 fluid for our S2K's. He just simply stated that because they are silicon based and non-hygroscopic, (will not absorb water) are good. Maybe not for our car's, but for a non-high performance vehicle without ABS.
