This is the second master cylinder. If I block both ports I can’t move the piston after the bench bleed. So I think it’s ok. My brother told me i have leak somewhere and air is being sucked in. I can’t believe that much air can come in and no fluid leaks out. I have gravity bled the system until no air comes out then pump the brakes. Still no pedal until the 3rd or 4th pump… then I gravity bleed and great more air. This has happened for several cycles.
I guess i could still have air in the master but not that much. The master is perfectly level in the truck so i would think the air would be purged when i pump the brakes. Im not an expert on brakes but I have bled many systems and never seen this.
I think the piston is traveling the entire distance with the pedal. I have it adjusted so that there is no play when the pedal is up. I had some play in there but adjusted it out to see if that would help. I will disconnect the rod and see if the cylinder is bottoming out at the other end. It’s worth a try.
Thanks
Rich
