Brake MC Reliability
Just a quick poll of you guys. Have any of you had your brake master cylinder fail in any way?
I'm trying to determine if I just need to do a flush or if the MC is failing. I don't get the typical soft-pedal-that-stops-and-then-sinks, which is typical of MC failure. I just get the soft-pedal-that-travels-a-lot-and-stops.
Trying not to spend unnecessary money/time if I can help it!
Thanks in advance!

I have replaced my MC. It started to feel like a little more than just the usual soft pedal and I figured it wasn't worth a second guess. I did get a small improvement from the new MC.

Update: did a flush and the spongy pedal did not improve. So if you have a spongy pedal after bleeding the brakes, it's likely the MC. It's weird that the pedal doesn't stop and then drop like most bad MC symptoms.
