I have 96 Acccord.
Rectenly, I have to push the pedal to the floor to stop the car.
But it happens occasionlly, maybe just serveral times one week.
And most of cases are happened when it is hot, usually in the hot afternoon.
I am in Texas.

I have checked it for serval times at two Goodyear autoservice store.

The first time,they told me everything is fine.(Good year A-store)

The second time, they told me to clean and adjust the rear brake. I let them do it.(Good year B-store)

The third time, they told me to change master cylinder, front brake hoses and rotors, loaded calipers front O\Haul which will cost more than 1100$. Then I go home.(Good year B-store)

The fourth time, they told me to change master cylinder, bleed-refill brake system and clean and adjust the rear brake. I was surprised at the 'clean and adjust rear brake' since I just did it one week ago. I feel no trust again.
