I have this odd sort of situation that's been going on for quite a while and I'm not sure what to make of it. It was exasperated in my last track day.
When the bike is cold, the front brakes work spectacularly. After a while or on a hot day, when the bike slows to say 20mph and the front brakes are applied, the front brakes chatter, very much like the rotor is warped (continuous, pretty consistent skipping). This is not seen in the cool mornings even at low speed.
Since I just pulled the front wheel off for a tire change, I loosened and re-torqued all the rotor bolts to spec, hoping this would resolve the issue; I haven't had a chance to ride it since the change.
Anyone have any thoughts on what might be happening? Could the rotors be perfectly flat/straight until they heat up, and then warp? If so, I presume my only option is to replace them, but how do I avoid this situation in the future? What are some possible causes?
