Brakes, or Why can't I use them?

[MartianDestiny]

Now, I know that the brakes are more effective (as bad as they are)

Get the brakes in working order so that you trust them. I won't get on a bike if I don't trust the brakes.

Simple adjustments to the cable tension, maybe some new pads, and if necessary a good oiling (the cable, not the brakes!) will make quite a bit of difference for very little $$ input. Cleaning off the braking surface well can also help.
