Missing Emergency Brake Spring? Assistance w/E.B.

Hello gang my first post! What has led me here is that I inherited my Dad's 1996 Tacoma 4x4 with only 30,000 miles when he passed last Thanksgiving. He only used it for getting out in snowy weather (he was retired) so obviously very low mileage... but he has not maintained it as one would hope over the years.... anyway... i'm relatively new to the world of auto mechanics, basically learning as I am fixing/tuning up our 3 vehicles... on to the (first) issue with the Tacoma.

First thing I noticed when I got the truck was that the brake light stays on all the time, and that the emergency brake does not work at all (to be clear, as in the truck is moving at 2mph and I fully engage the E.B. and nothing happens at all and the truck keeps rolling while in neutral). When I finally had time to investigate, I have been unable to find the spring at the rear of the vehicle that keeps tension on the brake, but I have been unable to find any good pictures to indicate exactly where the spring would be, and it is not evident under the truck where it should go either.

So for starters, can someone help me locate where the spring would be located underneath the truck for the emergency brake? Can anyone point me to any photos of this spring and/or where it is located to aid me in verifying this is my issue? Does anyone have any documentation on the E.B. mechanism or point me to it?

Thanks,
PJ
