Please vote and post an explanation, the outcome may surprise you!

nice..... this will definately help me...... thanks

define used?? id figured the best braking would happen after the parts have been broken in, used. for some reason i think that non slotted/drilled rotors with a good set of pads break the best.

Not too many votes...at any rate, yes used rotors with worn in pads will stop your car better than new. I wouldn't even begin to touch which application of rotor/brake pad combo will do the best, that's a can of worms well enough left alone IMO.



The reason used (between 500 miles and needing to be turned) rotors and worn in pads perform the best is because the surface area of the rotor and pad grow. Yes I said that, grow, now before you call bullshit let me explain;



New rotors and pads have a profile that looks like this_____________



Used rotors and worn in pads have a profile that looks like this^^^^^^^^^^^^



So while the diameter of the rotor didn't change and the length and width dimensions of the pad didn't change there is more surface area that makes contact between the rotor and the pad...more friction=stop better

bump..... thinking about getting brake rotors for martin's fd and i need help to decide

you want the heaviest rotors. the rotors job is to turn motion into heat. the bigger the rotor the more heat it can absorb. all the vents and slots remove mass and give cracks a place to start
