Soft brake pedal after track day

[del mar]

Morning,

Yesterday was my second track day at goodwood, on Saturday I replaced the brake fluid with motul 600.

Car has no servo or abs - the pedal felt Rock hard with very little movement. Towards the end of the session pedal was noticeably soft with loads of travel. The master cylinder was damp looking.

What has gone wrong here ?

Would this be a fluid or a pad problem ?

Thanks

Del
