I just recently replaced my master cylinder cause it would sink to the floor periodically when it would get hot it works fine now only problem is now that I put the new master cylinder I checked for leaks and it's leaking on both brakes lines and the right bolt on the master cylinder not alot but moist.i cleaned it with brake clean thinking I didn't clean it when I did the job but check it the next day and it was moist with brake fluid. Any suggestions? The master cylinder is a brand new duralast

 

Post pics of the leak locations.

Also, car information is always required when you make a tech thread.

 

Brake lines that connect to master cylinder and right screw that holds master cylinder to booster. I have a 92 civic si
