Hi - Brake question for those in the know...
HPDE this weekend and my brakes developed a moderate pulsation under light to moderate pedal pressure, but very light (or no) pulsation when braking very hard (near threshold).
Swapped the Carbotech XP10's out with the stock pads tonight after I got home and with a quick run, the stock pads seem to have a very very slight pulsation - but you almost have to be trying to feel it...
My first thought was uneven transfer layer - but after a bed-in procedure between sessions, I had the same issue when I went back out. My next thought was a warped rotor (or rotors) - one reason I swapped pads - wanted to get a look at things.
Attached are pics of the rotor right after I took the XP10's out, and the pads - the black areas on the pads are just brake dust - it wipes right off. Does this support a warped rotor?
Otherwise - how do these look - is the dark area at the center of the rotor indicate I'm only getting good contact for that ring vs. the whole rotor surface?
Thanks for the advice...
