I have a 99 Tacoma V-6 and a little problem with the brakes that I don't quite understand. The brakes have been a little spongy or soft for awhile and feel like the pressure is bleeding off slowly and the pedal goes down some and then at other times they act fine and are firmer when the pedal is depressed. So I figure the master cylinder is leaking and I'll change it soon enough when the weather warms up.
Well today waiting in line at a bank I shut the truck off to wait. While sitting there I was messing around and pumping the brake pedal to see what happens. The pedal is very firm and acting like the brakes should feel all the time. So with my foot on the brake pedal I started the truck and as soon as it started the pedal went mushy again. What is the problem, it sure does not seem to be the master cylinder any more.
Thanks,
Scott..
