I just installed a new rear master cylinder on my 2015 c-force 800 and I can't get it to pressurize. Any help would be greatly appreciated.

I know it must have air in it and I also know it feeds both the rear caliper and both front calipers. I also hear it's pretty tough.. if not impossible to bleed the system without a power bleeder. Otherwise with two people doing the standard bleeding, start with the fronts first then the rear..make sure it never runs low on fluid.

We have fought some issue's with brake bleeding & CFMOTO. I've used old fashion pump the pedal then mighty vac & pressure. Results are the same.

Don't be skeered of the old fashion crack the bleed & let it gravity feed. Or start with the longest line such as the RH rear & work up.

If you are able to get good pedal then it bleeds off after a period time, such as a day or two...post up.

Which bleeder screw on the front? There are 2 on each caliper.

Yeah the brake on the bars have it's own section in the caliper so..trace the lines from the rear and use the bleeders closest to those lines.
