Rear hand brake doesn't work after replacement on Varg EX

[notna]

Received my bike today and spent a lot of time assembling it along with swapping foot break with a hand break. There's no official guide on how to do it so I had to follow a couple of random youtube videos. At the end my hand rear break does not work.

I'd really appreciate some advice on what I could've done wrong. Keep in mind this is the first time I'm doing such kind of work on a bike.

What I did:
- Removed foot brake pedal
- Removed the brake pump after disconnecting it from the brake caliper
- Disconnected the thin black cable (power?)
- Connected the left hand brake directly to the break caliper passing the cable all the way through the body of the bike
- Connected the black wire from the left hand brake to the wire box

While doing it I also unscrewed the little bolt from the caliper and leaked a little bit of oil. I screwed it back in.

What are all the mistakes I've done?

Needs to be bled properly for a start
as in from the bottom up with syringe
go from there
there is utube vids on that

So the fact that squeezing the brake is too easy should have told me that I haven’t bled it properly? Alright
