hey all. i have a 95 ex sedan with 4 wheel abs. was driving around and my brakes were working flawlessly for 4 or 5 miles. suddenly my brake pedal got extremely hard and had no movement to it so i kicked it as hard as i could. as soon as i did i lost all braking pressure. i thought maybe it was just air in the lines or a vacuum leak but bled them fine and don't see any lines under the hood that correlate with the booster or braking system that don't look right. also thought it might've been my electronic master cylinder cap but replaced that and the issue still persists. maybe the master is leaking into the booster or there's an issue within the booster? the fluid level in the reservoir hasn't changed at all except for when i bled the brakes. anybody know what might've happened or a fix for this issue?
