I once had a Ford Motorhome, around 92 vintage, with front disc brakes. Large size for E-350 chassis. Brakes seemed to work ok when cold , but It had a problem which occurred after driving for an hour or more. The brakes would fail almost entirely, with good pads and shoes, properly bled without warning. Very scary! The e-brake would still stop it, but gradually. I finally figured out the problem, after a long stint on the interstate, the brakes failed on a two lane road with stoplights. Luckily I was able to make a turn and get stopped with the E-brake. I decided to feel of the wheels to see if one of them was hotter than the others and sure enough, the front left wheel was too hot to touch. The conclusion I reached was that the front left caliper was not retracting at all keeping pressure on the rotor, causing it to overheat and boiling the brake fluid. I changed the caliper and rotor on that wheel and had no more problems. Pulled my hair out over that one.
