Chock your wheels and release the brakes. Do a walk around. If you hear air escaping and pinpoint it to a chamber, then you have a bad emergency chamber... in which case, you'll probably hear it escaping from the purge valve between the two axles, and you'll need to take a set of pliers or vice grips and pinch off the lines to each chamber to determine which brake chamber is bad.
After that, press the treadle valve (brake pedal)... I use a hood prop rod for this... you can buy them at any auto parts store, although I bought mine from Snap-On (they're also handy for when you have to adjust a clutch). Check again for air leaks... if it's coming from the service chamber in this instance, it's a problem with the service chamber, and you should be able to pinpoint the specific brake chamber by sound.

What causes your brake caliber to go bad?
Answer: Brake calipers (front or rear) normally "go bad" because the dust seal was not replaced, thus allow dirt to get onto the piston as the brake linings wear down. When you go replace the linings and DON"T clean the piston, it allows the dirt to damage the caliper bore. NORMALLY, brake calipers leak and can be overhauled with a few sealing rings, and a good bleeding of the brake system.
How can you fix your air brake chambers?
First, you need to determine if that's the problem. If you have a co-driver, or someone who can simply push on a brake pedal, get them to help you. Kneel down at the end of your trailer while they depress the brake (they can use the foot brake or the Johnson bar - it really doesn't matter), and listen for sounds of air escaping. If you hear that, get under the trailer and try to pinpoint whether or not it's coming from the brake chambers.Obviously, while you do this, you'll have your tractor air pulled out to engage the spring brakes on your tractor, and your emergency/trailer air pushed in so that air continues being delivered to the trailer.There could be a number of reasons for brake chamber malfunction, but the most common is simply a bad or worn out seal. Inside the brake chambers, an "O" shaped rubber gasket can be found. They do go bad over time.Your problem might be with your brake chambers, just as it might be a problem with air line crimping or other blockage, or with the brakes themselves (although brake problems don't often happen to all sets of brakes on a trailer at once, but discount no possibilities until you know for certain what it is).If this is a government-owned vehicle, they probably don't consider this an operator level task, and would have you either take it to your unit maintenance, or they would summon a professional third party entity to conduct the repairs.
Where is the brake shift interlock solenoid located on a 1999 Ford Windstar?
It is on the steering column, but those rarely go bad. In fact, I have never had to replace one. Almost always it is because you have no brake lights. Possibly a bad brake light switch.
