Hey guys -

Just curious, at what point do you change pads? I was checking yesterday and my front pads are down to about 50% remaining, and I was debating whether to try and get one more weekend out of them. They've been on for a double school (Roebling) and the first three MARRS races (including two test days). I know the ability to dissipate heat goes down as the pads wear, but I'm not sure if the loss is proportional to the wear, or if the there is a point where it falls off dramatically. Btw, I'm using Blues on the front and HP+ on the rear.

One other question, do you always change rotors when you change pads? I have been, but am not sure it's necessary.

Thanks,
Earl
