I changed the brake and clutch masters in my 76 X1/9. I put everything back right, I think. Or at least the way it all came out. I replaced the hoses too. I am trying to bleed them, what a pain in the a**. When I try to pump them up I am not even getting any bubbling in the reservoirs. I could pump all day long and I don't think they would take any fluid. I think I will loosen some lines and let gravity work over night.
