I have a 1995 Ford Ranger 4.0 6 cyl with 5 speed manual transmission and am having brake issue with it.

I replaced both wheel cyl in rear, booster assembly, adjusted brakes and bled till i got clear brake fluid in lines.

When i apply brake pressure, brake fluid is leaking out of small reservoir tank for clutch master cylinder around 90 degree fitting
Clutch is out of gear when apply brake pedal pressure
Almost seems like bad o ring or seal
At a loss for what is wrong
Would this have to do with clutch master cylinder if apply brake pedal ?

I dont see any leaks around master brake cylinder
Thank you
