This is exactly what brake fade does! Ask anyone that’s tracked cars hard. Fluid gets hot and things get spongy in a hurry.

I would suspect that the bad adjustment overheated the drum, which then weakens the entire braking system. Have an unassisted like in the morgan and you’re close to the floor under normal conditions, the threshold to hitting the floor can be minimal.


If brake fade is so bad that the pedal hits the floor, then the primary cause will be VERY old fluid that has absorbed moisture and reduced its boiling point dramatically. This moisure when hot forms bubbles in the fluid, which of course being compressible then proceed to do just that, losing all your braking ability. Anyone experiencing a really, really long pedal after a hard ession on track should look to change the fluid before the next session. A condition like this on the road should never really occur however, but if it does, then something is significantly wrong with the braking system and wants addressed ASAP.....!
