The front master cylinder is probley in need of replacing.
Have you changed the fluid?

Sounds like bad master like Alex said or a blockage in line. If you kinked the line it may not be flowing back to master.

How much and what all is needed to run it?

 

[alex456123]

It's really just a newer style master cylinder, I imagine its plug and play.

yep just bolt your existing brake line to it

i ve had the same problem. after a a small ride the brakes lock up.i let it cool and the wheels would spin again...
it was the thumb throttle pressing just a little bit against the brake lever enough to rub the pads against the disc causing the brake fluid to expand due to heat and lock the brakes.

^^ I would pm him for a more direct response and maybe a quicker answer

 

[Likibow]

thanks I'll check if it's pressing the brake lever

 

[Likibow]

well I've checked and what i found was the push rod seal was broken and brake fluid was coming out of there, then i noticed that the seal inside where broken too, had no brake fluid pressure in the lines, when i pulled the lever it was extremely soft, anyway bought a new master today got pressure, lever is how it used to be so i'm gonna test this weekend and see if my brakes don't lock up this time keep you posted.
