Default Brake problems. Help please

I built a go kart and i just can't get the brakes to work good at all. IT has 20" car wheels and it weighs at least 400lbs without a driver. I have 2 honda motorcycle calipers setup on the rear axle. I have bled the brakes and they are good, but i still can't get it to stop reasonably. Not sure if the master cylinder doesnt have a long enough stroke to put out enough pressure and i need a bigger master cylinder or what.? I have 8" rotors, maybe that's the problem.? I

Even if you can't help with troubleshooting then maybe you can tell me a brake setup that will work. (Really considering mechanical now lol)
The pic attached is mine, touched up a few spots and got overspray on it, which is reason why it looks discolored.
This is also the link to master cylinder i currently have. The pic is also attached Any info is greatly appreciated!!

Are the calipers fixed or floating? Fixed may dampen your braking.

We need pictures of the entire brake system but I'm betting that master is too small for the calipers.

see..
My bet would be on calipers too small for the kart...

I mean motorcycle calipers can be anything, from 205 horse CBR front calipers
(stopping power of a dropped anchor)
to 10horse MBX rear calipers (stopping power of a dropped anchovie)

And with car whels, the rotational mass is far beyond what small to midsize motorcycle brakes can handle.

combine smallish motorcycle brakes with the small master cylinder up there and
hitting the brakes is as effective as waving the kart to a stop.

More like opening your mouth and hoping the drag will stop you.

It’s heavy. It needs front brakes or else it will never stop correctly.
