Bought my son a 2008 Sportsman 300 and it had a very faint back brake pedal. Thought maybe the pads were worn so I replaced them but still no difference. Got a new rear master cylinder, swapped it out, and now I have problems with front and rear brakes.

The front brake lever pulls in with no resistance unless the rear brake lever is depressed. I tried bleeding the front brakes and still no good. The rear brake doesn’t even build enough pressure to bleed the rear system.

Any ideas???? I’m at a loss here.

Thanks
Rich
