Is it? I have been fighting with my brakes for sometime now. I am at a loss. I replaced rear calipers, pads all around, turned rotors and new MC. I have been through the archives about the bleeding sequence and It appears that the fluid is running through well. I hope so because at this point I have gone through much fluid, more than I feel is even needed. I have come to the conclusion that there is an air leak and I may have pin pointed it. The old resivoir sits on the rebuilt MC not as firmly as it sat on the old master cylinder. I replace the original MC with a rebuilt one went through all the rigamaroll to prep the MC put it on and commenced the bleeding procedure went through a learning curve on that although came out alive. Once i finished that procedure i turned on the vehicle to my dismay the brakes fell straight to the floor with no kind of resistance at all. I pumped them prior to turning the egnition and held them in place and they slid down slightly and when i released and then depressed on them once agian all the way down. By this time I had to call someone else to the scene who had experience in the mechanical field. He thought that it was the mc once agian so I replaced it went through most everything else and still no go on the brake thing. My patience...GONE. The only thing that I think that it could be is that the resivior doesn't sit on as tightly as before. It kinda wiggles back and forth if you bump it. Someone anyone tell me if i am wrong or tell me what is wrong could should be wrong. I need all the help I can get before I take it to a Mechanic (AHHHHHH). My pride is tarnished now.

Thanks
