Just when i thought i fixed everything; my '93 civic's brakes locked up or something. All i know is it started with me having to sit at a light for a long time cause of a train. Then when the light turned green and i let off the brakes and hit the clutch and gas, the car acted like it didn't want to go. I revved up the motor and then popped the clutched and then it stated going but it was struggling to just hit 35mph. I had about .25-.5 miles to drive with the hazards on at 35 before i could pull over. while i was waiting for a chance to pull over i noticed that the brake pedal was really hard and i noticed it was cause it was already all the way down. When i pulled over the first thing i checked was the pedal and i didn't see anything keeping it locked and all of a sudden it just released itself. When i got back into the car and drove home i noticed that the pedal was now traveling a lot further before it would activate the brakes. I replaced the master cylinder maybe 2 yrs ago so i don't know where to start. I feel like this car is just cursed, it's stumped even the best mechanics.
