I don't know if I'm finally starting to brake hard/late enough or just noticing, but halfway through my last track day my brakes started to fall off. Normally I get typical Brembo bite very early in the lever travel with minimal effort. But towards the end of the day the lever would go deeper into its pull before I got the braking action i wanted. Has anyone noticed brake fade with the stock rubber lines? Is it time I upgraded to steel braided?
