Bought a polaris 400l 4x4 had just working rear brakes.the front brake line was cut and master cylinder removed got the parts to fix it.now I can not get the breaks to pressure up .tried bleeding with nno luck .anyone got any ideas thank in advance

 

Try a mityvac if you haven't already. Usually makes short work on jobs like this.Would also help to prime the master cylinder first by holding your thumb over the end and pumping the lever until fluid squirts out.Then you'd have better luck on pumping up the master cylinder and bleeding lines. Bleed at the rear caliper first,then front right and then left.If you still have problems you can try reverse bleeding starting at the rear caliper.
