I just purchased a brand new hand brake master cylinder for my 2001 Polaris sportsman 400. When I got everything ready to bleed the system I noticed after pulling the brake lever 8-10 times that there was zero pressure in the handle and the fluid level wasn’t going die at all. I finally pulled the banjo bolt out and depressed the handle numerous times….. Absolutely no fluid was leaving the master cylinder!! Any ideas? Bad m/c ?
