hi I’ve been trying to bleed my brakes for two days now. I’m working on a 1993 Honda Civic. I recently did a rear disc brake swap on it. Then I had to change my brake booster. While I was doing that I went ahead and changed my master cylinder. For some reason when I’m bleeding my brakes i get nothing but air. I’ve bench bleed the bmc. It works fine. The pedal will not stiffen up. Please help.

 

I would first check the linkage from the pedal to the master cylinder is connected/aligned correctly. It may have come out of alignment when the old one was removed. Next try bleeding in this order RR, LR, RF, LF.
