This made the world of difference on the track. The PFC pads don’t have much bite (quite a bit less than stock) until one or two hard brakings to get them up to temperature, but after that they are solid on the track. I only felt a little light softness towards the end of a 20-25m session. This may have been as much the impact of the Castrol NRF brake fluid which boils at a much higher temperature.
Which compound are you running? No track pad is going to work well until it has warmed up.
