I was driving yesterday and noticed when i press the brakes the car tries to stop but then the pedal starts fading away and goes all the way back i tried pumping several times its even verse. I checked the fluid level looks normal no abs light what can this be. I have fairly new brakes in the front and old ones needed to be changed. I was shocked good thing i was not going fast. This happened after a an hour of driving and it was very hot in NY about 95 degrees. Please gide me in the right direction. I left the car home today did not want to take a chance driving it. Feels like a loss of pressure.
