My front brake's cam doesn't work anymore. It is seized up, so that when you rotate the lever, the cable bolt rotates too. If I hold the cable bolt with an allen key, then I can rotate it, so it's not 100% seized.
I'm trying to take it apart, clean it and reassemble with some fresh grease. However, it's not coming apart with gentle force. Assemblies 19 and 20 come off fine.
From the exploded diagram, it looks like I can push on the thread on the frontside where the small screw was located, and that should push the rear assembly out. I tried with modest force with a screwdriver on the back too, but it's pretty stuck (I guess the seized running surfaces for rotation are also the same surfaces that need to slide on each other to pull it apart).
I've not pulled one apart for a while, so don't remember if there was a trick. My google ability is also not providing answers.
Any good trick to use? My next try will probably be a longer bolt in the front and pushing with a vice to press the two pieces apart. I just don't want to jump in their with more force and do some damage. This brake was an eBay purchase a few years ago for my fixie, and I don't want to spend more money on the bike (but I do want a working front quick release).
Thanks.
