Getting ready for a track day tomorrow, on the advice of Honda-san at Prince Motorsports, changed out the front pads. Had on the PFC racing pads; decided to try this time, Nismo R-tune pads.
And look at these photos - I don't think I could have safely stopped with these on. I was told they only had 3mm left, but actually...
Look at this - the material has literally ground away... incidentally this was from the front left wheel - the one that tended to shower sparks upon hard braking.
FYI - ever wonder why stock brake pads make that awful squeak indicating the pads need replacing. Because they have this "finger" that scratches the disk rotor when there is very little pad left.
