Q: Brakes intermitently mushy
The past few months, my brake pedal has been going to the floor randomly while braking. It doesn't always happen. I was recently in the car roaming around for a quarter hour, stopping often, and I couldn't make it happen. The fluid level looks fine. Today, it happened several times. After it had sat for a while, it felt like the brake pedal was mushy when I first put on the brakes. I drove it around. Of course, the problem disappeared. What's going on? If my master cylinder is going bad, would it be intermittent like this?
