So, I have a break calliper that needs to be replaced but I've been putting it off because I've been thinking about selling the car and didn't want to spend the money if I wasn't going to have the car much longer. Needless to say it wears down my break pads a little quicker than normal. Well I have been putting off replacing them recently even though I can hear them grinding because I just haven't had the money. Well today I was driving and all of a sudden my breaks went to the floor and I had to use the hand break. I checked my break fluid cap and it was loose so I tightened it and it fixed the problem for a few minutes. For the rest of the drive I had almost no breaks. Does anyone know what might have happened?
