    I've completely disassembled my Colson Snap Tank.

    I'm wondering if these brake disks are still good, or should they be replaced?

    Picture 1 is side one. Picture 2 is side two.

    (Too hard to tell?)

    I used to know an old Schwinn shop owner here in Hermosa beach who used
    to re-surface those disks by hand... painstaking process
    Sand paper in different grits

    Those aren't bad at all. I resurface them by hand with whatever roll of sandpaper is hanging in the parts Dept. Usually 80-120 grit. Then finish them off with a Scotchbrite pad. Wash them off with brake clean and dry them with shop air. Fill a spray paint can cap with 30wt oil and let them soak.

    They look good to me, but you may want to resurface them as mentioned above. If the edge of any tab catches on your fingertip, file it down smooth and you should be good to go after sloshing 'em down in some 30wt motor oil or something similar.

    After you're done the stack should measure 0.750". This is the thickness when new.
    The shorter the stack, the more kickback required to engage the brakes. Also, due to wear of the clutch sleeve and inner surface of the hub, you make have too much kickback for your liking. More discs can be put in to shorten the play.

    There isn't much about these hubs I like, but that is one nice little trick I learned about them long ago. When a Morrow has too much kickback, unfortunately you gotta replace a bunch of parts to fix it. Nice tip, way to share. :cool:

    One day Scott(rustjunkie) and I were rebuilding the rear hub on my HTB Monark when he suggested adding a disc to lessen the kickback issue I mentioned. Worked like a charm.

    Looks great. Keep that tab on the spring in the drive clutch slot. Nice axle jaws.
