Master brake cylinder gone bad?
I've tried all suggested methods to firm up my (ABS) front bakes and recently rebuilt my master cylinder and replace both front calipers but the brakes are still softer than they should be and I often pump them to stop properly. I tired the zip tie method on the brake lever and leaving it that way over night. It didn't work but what I did realize is that if I hold steady pressure on the lever it eventually bottoms out onto my handgrip. So I don't think there's air in the line as I've pumped/bled over 2 quarts through the system, but perhaps my (rebuilt) master cylinder it still may need replacing. Any thoughts?
