Ok, well I have a 93 del sol, it starting squealing bad so we changed the rear brake pads which stopped the squealing. But, a couple days later the brake light came back on and you had to press the pedal to the floor in order for it to stop. We put some brake fluid in it and it helped for a day but went back to the way it was before. But now the brakes aren't working at all and I don't know why. Can anyone help, I'd rather not take it to a shop and fix it myself.
