Hello everyone,
I have a 97 civic with a gsr swap, I was driving one night and I went to press the clutch and the pedal was very easy to push and it stayed on the floor. Just bleed the clutch and go, right? Wrong. I bled the clutch and continued to drive home thinking I fixed it, then after being on the highway for about 20 minutes I went to press the clutch again, and the same thing happened. The clutch master cylinder and slave cylinder are both brand new. I should probably include that my diff is welded from previous owner (facepalm), if that has anything to do with it. After bleeding the clutch every time it feels stiff as can be, then as driving I notice the clutch travel will increase, then after a while the pedal will be soft and stay on the floor. Any help is appreciated!!!

Find the leak. It could be the reservoir, any one of the line couplings, or you got a bad master or slave.

Either way, you should be able to find fluid somewhere along the system to pinpoint where it's leaking from allowing you to eventually suck air.

You may have to clean it all up, fill up the reservoir, make sure it's all dry and just pump your clutch repeatedly in your drive way and then inspect for the wet oily spouts that the leak of brake fluid will make.

If there are no leaks visible at any of the connections, peel back the boot at the slave. If no fluid is present, replace the master.

How did you bleed the clutch line? Did you use a bleeding system (bottle/valves)? When I replaced my clutch master cylinder i didn't bleed it properly because there was still air in the line. I made a homemade system with a soda bottle filled with fluid and a vacuum line so that it was completely closed. Some air could still be trapped in the line, even though the clutch pedal firms up.

You definitely want to be sure that you properly bled the hydraulic system. If so, the MC and/or SV may be bad out of the box.
