well i have a scary(not that much) brakes story:
I was driving in my father's 1984 pajero when i was going into a round about, i hit the brake and the padel went all the way in and the car slowed down slightly. so i removed my foot and tryed to break again when i found that the padle is realy hard to press. but when u press it with power only the rear brakes work like a hand brake.
so with all my power i pressed it and the rear wheels locked and started to slip but fially i stoped it.

The problem was in the master cylender, i didn't realy know what it was but the master cylender was replaced
thanks god i didnt go into the round about
