That is difficult, because basically, you have bought a custom bike. Normally adjusting hydraulic brakes comes in 3 parts.

Make sure there is material on the brake pads.
Make sure free play is taken up if they have an adjuster.
Make sure there is no air in the system.

There is some generic help in the link.

'TRAM' Trike is unknown unless you meant 'Tram*'? (with a P)

I see Fixya Profanity Filter doesn't like that 'T' word!

For a battery to go dead on you like that there must be something draining the battery while the vehicle is switched off. It could be something like a which is not switching off or a short across some circuit that does not show up on any light. The first and easiest test is to disconnect the battery negative cable whenever you park the vehicle overnight etc. and see if the battery still runs down.
As a more positive step disconnect the positive lead from the battery and wire a bulb like a tail light bulb, between the terminal and the removed lead. The bulb should light up. Make sure that everything on the vehicle is switched off, the bulb should still be lit. Remove and replace the fuses one by one until the bulb goes out. That is the circuit that is running your battery flat. Check all the components on that circuit until you get the light to stay out and your problem should be fixed.
Check your charging system. With the engine running at about 2000 rpm, a volt meter across the battery terminals should read around 14 to 14.5 volts and drop to about 13.8 volts with the engine at idle. If this does not happen, the charging system may be defective. Even with lights on the voltage should climb, but will drop lower at idle.

Make sure the battery is good, ie. no bad cells........should read 13.2 volts min. Take it to any local parts store and have them load test the battery. If battery tests good, make sure that the charging system is not putting out more that 14.8 volts max. If it is putting out more than max, replace voltage regulator/rectifier.

I would check you fuses.

I image when you put the battery in backwards, you blew at least the main fuse on your bike.

Try to check all the bolts tht holds the engine to the frame they could be lose.
I had a similar case and only to find tht the engine mounting bolts were lose the bike was Bultaco 125 sherpa.
Hope this helps!

try looking for the idle screw in the following place...
standing facing the side of the bike that has the clutch on it.
look in the area between the front cylinder and the rear cylinder, close to the tank.
the screw is black and can be difficult to see.
hope this helps.
