I do most of my own bike maintenance now, except I haven't really learned how to work on the disc brakes on my mtb. I'd like to get some help on doing so now, though.
I needed to shorten the front brake hose a few weeks back, but I didn't have whatever I would need to do so, so I took it to my LBS. When I got the bike back, the front brake lever was way too soft, almost reaching the bar when I'd brake, so I took it back to the LBS to have them readjust it. Now, it's still a little too soft for the most part. Sometimes, though, the lever will brake pretty stiff at first before going soft again.
From what I've read, I'm guessing this might be a bad bleed(?) Does this sound right?
