Default Both "Master Warning and BRAKE" light comes on while making a turn...

Long time reader, first time post… I need some help from the community. While slowing down to make a right turn tonight with my blinker on, the “Master Warning Light” and “BRAKE” (type A, e-brake) light came at the same time. A few seconds after the turn, they turned off. Slowing down for another turn, blinker on, and both lights came on again, but they stayed on a bit longer before turning off. Has anyone experienced this problem or know what maybe causing it?
Thanks for your help.

Thanks for your help.
Most likely a low oil level.

Oil level is ok. Thanks pwpanas!

I went to start it up today, and now both light are staying on... I shut it down and restarted the car (hoping the lights will go away), no luck they're still on. Any other suggestions? I also noticed that when I looked under the hood for anything that may cause the problem, I heard a hissing sound coming from the "Resistor Pack Part# 28515-46010" (at least I think it came from it) when the car was off. Is this normal and can this be the problem or is it another issue that I have?

Thanks

It's not normal for the resistor pack to hiss. Although this is part of the electronics (obviously), I doubt it's related to your oil sensor.

If your master warning light is on, you'll be able to read the code(s) to determine the problem.
