Old cars will do this. Gently applying the brakes limits the brake caliper temp. But applying the brakes with force will quickly heat up the fluid/water to steam and lock up the tires - so instead of stopping - the vehicle slides right through the intersection!
Sounds like you have an air pocket that moved from the master cylinder past the piston to the brake line. Then later moved back into the master cylinder. Either way, a brake bleed is in order.
I hate to be that guy but........you're wrong. Look it up. Steam compresses and will cause a soft or spongy lever or pedal just as I described. It's also the reason why when the fluid cools and the steam goes back to being a liquid it will behave normally. I won't bore everyone with the links, unless I have to. It's an important subject and people should know the correct facts, so I can't let this one stand.
