Re: [VAC] Brake Magnets

[Jim Dunmyer <jdunmyer@xxxxxxxxxxx>]

John,
 You have it exactly correct. The little spring serves to keep the
magnet in constant, light contact with the "armature" face of the drum.
This is necessary so that when the magnet is energized, it'll create
drag, pulling the actuator arm around to apply the brakes. The "other
hole" and pin is just to keep the magnet from spinning around and
ripping the wires off.

Remember to dissassemble the adjusters, clean and grease them before
reinstalling them. Pay attention to which way they must be turned to
tighten the brakes, they can often be installed either way. Although I
always try to install mine so that I move the adjuster tool 'up to
tighten', the only thing that's important is for you to know which way
YOURS turns. It goes without saying that you want them to be all the
same.

I also ususally put a tiny dab of grease at the cam and other wear
points. Make sure that nothing is frozen up, that everything moves
freely. Don't forget to clean and grease the seal surface on the spindle
or the seal will be destroyed very quickly.
