Thanks for the help! The reason for removing the lever is because the part that holds the cables onto the lever is broken. The handbrake still works but sometimes the cables fall off when not engaged.It's very simple.
Detach the cables (back off the adjustment nuts, until the spreader bar falls off of the finger.)
That U-clip on the right side? Pry it out slightly at the top, and press it down in the direction of the U.
Slide / press pivot pin out of the assembly. At this point, the ratchet/ pawl mechanism kinda falls apart, and the handle will come out of the vehicle.
Note that the ratchet wheel (what the handle rotates around) also hooks onto the bracket for the handbrake lever, and said bracket is part of the vehicle body.
Putting it back in is a bit more fiddly, as the center pin is what holds everything together.
Just out of curiosity, why the need to remove yours?
