thanks for all the help guys you are absolutely correct about the no break fluid, my brother was driving it the other day and the break wouldnt engage until all the way down. I think im going to have to bleed the brakes because air must have gotten into them because after putting more fluid in it still doesnt engage.

I didn't think about the warning light indicating a brake system problem. Sorry about that! These Mustangs are so new that the thought of hydraulic problems didn't occur to me.

If it works the way it did in older cars, the light lets you know if one half (front or rear) of the brake system has lost fluid. The only way it would go low is if you have a leak. So that is something you need to check very carefully. In the older cars a bad master cylinder would also light the brake warning light.

Definitely bleed it as a first step and then carefully check for function and leaks before trusting your life to the brake system.

Let us know what the outcome is. I know that many of my other cars would illuminate the brake light on the dash with low brake reservoir fluid, sometimes even if it was just below the "max" line.

Most of the time, the 'brake light' means fluid is low or the handle is pulled up at least a little.
But keep this little tid-bit in the back of your pocket as well. Recently I fixed a 'brake-light always on' issue on a '98 Ford (not a Mustang), and the ABS light was always on, too. As it turned out, the belt was slipping and not enough power was being supplied to the battery, hence voltage was too low. Very unusual symptoms, oh yeah, the headlights were a little dim, too.
But the brake light switch circuit just had, also, the fluid level and parking brake on sensors, so it's a simple dual-function circuit.

the stang is back up and running I bled the front brakes yesterday and it seemed to have fixed the issue. Thanks for all the help guys

You should bleed all four brakes just to be safe. Start at the caliper furthest from the master cylinder. RR, LR, RF, LF. Also, you probably understand this by now, but it's not an emergency brake light. It's a brake warning light for the whole system. Most cars work exactly the same way, nothing special about the way it's handled on the Mustang. .

if all of the above fails, the simple solution I found was pull the parking break up has hard as you can to the extreme than release it again.. simple but effective!
