I replaced a broken brake line on my Cforce 800 a few weeks ago  and had a nightmare bleeding them , i have never in all my years had an issue bleeding brakes till this i tried reverse bleeding etc anyway to cut a long story short i had read that if you pressurized the master cylinder reservoir and open each bleed nipple in turn this would work AND GREAT NEWS IT DID because i live in the in the middle of nowhere i had to rig up my own tool for this i thought i would post the pics in case anyone else has this problem

Very creative & good on you 

I agree 100% on the nightmare that brake system is, CFMOTO cannot even offer a proper procedure. It's pathetic a decent service manual isn't in existence for as long as they say they have been producing vehicles.....any of them 

 ctdls I agree one hundred percent I managed to find a service note sent to dealers online from cfmoto explaining how to bleed a 500 side by side if I can find it again I'll post it

Check this like link out it's from cfmoto about bleeding brakes

Yes, I've seen it & have a copy somewhere. Just as bad as the system design itself, then you complicate it with sub-grade component manufacturing that leaks air where it is impossible to find & identify 

True

I mentioned it somewhere else & will do so again if some poor unfortunate person is searching trying to bleed this system. This is in addition or an alternative to your method 

Pump the handle bar lever & foot pedal then then secure them in the pressure position. Let them sit for awhile, sometimes over night. This will push the air out & you will be able to pump them up.

You can then try & bleed normally, you may end up losing pressure again & need follow the previous method. I've also had everything pumped & bleed properly only to loose pressure again after a few days. Then you may have a component leaking & you have to try & identify which POS it is
