Well, its not really permanent. You can sand it off!!

thats why i said permanent-ish.....

Correct me if im wrong, but isnt it that speed is converted to heat DUE to the friction.
So mirror smooth finish = less friction = less speed lost.

Cool....will see if its worth it at a later service....

Well, this is another one of those things that I know in my head, but when it comes to putting it down on paper, or the PC in this case, I kinda lose the plot! So, with some assistance, this is basically what I meant...

"All friction material (the materials brake pads are made of) has a coefficient of friction curve over temperature. Friction materials have an optimal working temperature where the coefficient of friction is the highest. Sometimes you can use the brakes so hard that you get the temperature over the point of maximum friction to where the coefficient of friction curve starts to decline. "

Hey Rtech,

Awesome link man!
Didnt know about green fade! (thank god for traffic, otherwise i sure as hell wld have had some of that the day i got my pads replaced!...lol.... actually i was kinda cautious coz i wanted the pads to bed in properly...but had no clue abt this green fade stuff..lol
