Why do I have to Pump The Brakes on my 2001 Arctic Cat 500 4x4?

I have a 2001 Arctic Cat 500 4x4 Auto,


Every time i go to break i have no Brake pressure and I have to pump the brakes 6 times to get them to stop.


Why is this?


How can I fix it?


Thanks|||Either you have air in the brake lines, or the master cylinder is leaking past the piston...does the master cylinder keep losing fluid? You may also have a bad slave cylinder or broken brake line somewhere...
