Thank you all for responding!! I was able to find a used MC from a salvage yard with the rubber cup in the proportion valve intact. I do have a bleeder in the steering column and I cant get the bolt loose. I will be trying your advise on getting that loose. As for the bleeding part, I'm going to try the conventional way first. With that said I have bleed my car brakes many times over the years. Are motorcycles basically same way, push on the rear brake pedal, hold, loosen bleeder screw, tighten bleeder screw, release rear brake pedal (Repeat, repeat, repeat)? One dumb question: If I pump the brake pedal multiple times does the fluid travel up the line or am i just pushing it back and forth with every pump? Thanks guys!! Jakub

Hello, I working an 83 Venture XVZ12. I recently purchased a master cylinder rebuild kit and replaced the the components. Now I'm trying to bleed the rear brake but it seems that I'm not not making any progress. I have read numerous post on this site and feel that I'm doing this correctly, but my pedal is not getting any harder nor am i getting fluid at the back l caliper. I loosened the bolts (i cant remember the name of this bolts going to the front and rear caliper at the MC and i have fluid coming out of both. I did notice a small tear (picture attached) in a rubber seal in the proportioning valve. Im wondering if that tear is causing some of my issue. Also, i checked the valve at the steering stem but a cannot get it lose. I have been spraying blaster at it for days but it will not let loose. Any suggestions would be greatly appreciated on how to loosen that bolt. Lastly, I don't have a vacuum pump, I'm trying to bleed these using the old fashioned way just like in cars.
