Hello everyone
I am in a tough bind here. I just got screwd by a friend that sold me this up van. Any way, yesterday I was out with my 4 kids and all of the sudden , NO BRAKES! Pedal go's to the floor but if you pump it you can get the van to stop. I have looked all over and no leaks at all. I replaced the master cylinder and still no brakes. Just keeps fading to the floor. When I press the brake it makes a air leak sound from the back under the van??? I'm lost here, I have a air leak sound that goes away after 2-3 pumps from a system that is not leaking anywhere, Clean fluid all around after the replacement of the master. I believe the sound might be coming from this piece in the back that I think is a proportioning valve. I think. The sound is being incredibly hard to pin point. I have even tried using a stethoscope on the lines to try and narrow it down.
Please help with some thoughts as soon as possible. I start a new job next week and there is no way me and my wife can shuttle 4 kids with one 4 dr car and get both of us to work! It's Monday and I start next Tuesday!
FYI: I'm an ex mechanic from years back and never had this issue with any of the imports I worked with before, I am capable to do anything so all thoughts are welcome!
