Did a session at the ScoobyZone trackday at Castle Combe, and 2 corners in, the brake pedal went to the floor.
Its got new Mintex 1155's on the front, new standard pads at the rear.
Black diamond grooved discs (on their second set of pads)on the front and standard Subaru discs on the rear.
Goddrich braided hoses all round.
Home made master cylinder stopper. (not ideal but its better than nothing.)
The fluid was completey changed after a track day at Keevil about 3 weeks prior to this. (brakes were vague and soft at best, was being outbraked by everything)
I've done the searches and checked what people have suggested:
The calipers are the right way up.
The wheel bearings are fine.
The hub nuts are done up.
No particular bedding in method (never needed it before) probably did about 300miles on the new pads before the SZ trackday at Castle Combe.
Have bled them again this morning.....no change to the amount of pedal travel.
What could have happened at Combe to make the pedal go to the floor?
And is there anything I can do about the amount of travel on the pedal?
Cheers in advance.

for the pedal to go the floor it sounds like either you have a really poor qulaity b/fluid or a lot of air in the system??
