Hi folks. My Brent wheel has been plugging along nicely for many years. Then, as I pressed the pedal, i felt a little "pop" and it quit.
I unscrewed the bottom, and discovered a little white fork (like a tuning fork, y-shaped) whose tines had originally been on either side of a black lever which speeds and slows the wheel. I managed to pop the black lever back into place between the tines of the fork, but it pops back out. The plastic parts don't seem to be bent or stressed, particularly. So here are my questions:
1.) Was there originally a little ring, cotter pin or fastener holding the two together? I might try to invent one.
2.) If the problem is that the black lever is somehow gummed up or gritty and doesn't slide as easily as it should, would it be safe for me to lubricate it with WD-40, or would that damage the works?
Thanks in advance to anyone who can figure out what the heck I'm trying to describe here.
Yours, Kelly in Ohio

Dear Kelly,
Sorry it's taken a couple of days but I had a look at the inside of my Br=
ent footpedal. If your "tuning fork" is about 3 and threequarter inches l=
ong - a tapering white plastic rod with two "pins" or prongs at the end w=
hich hold the black sliding lever between them, then we have the same ped=
al. In my pedal I don't see how the two could ever pull apart because the=
other end of the
tuning fork goes round a metal shaft or bar that goes from one side of th=
e foot pedal to the other. This allowes the "tuning frok" to move up and =
down - pushing the sliding rod (that alters the speed) up and down - but =
cannot move from side to side. It is attached to the metal shaft with a s=
plit pin - could this be what has popped out so allowing the "tuning fork=
" to slide along the
shaft and therefore away from the slider control?
I have some diagrams of the footpedal workings, as well as the control bo=
x, that I was sent when I needed to work out how the thing works. As I sa=
id in previous posts, it was broken when I got it 2nd hand and cheep.Anyw=
ay, I'm sending you an annotated diagram of the internal bits of the foot=
pedal directly - hopefully that will help you see how your pedal SHOULD =
be.
By the way, anyone have any wiring diagrams for a Brent B control box tha=
t they would be willing to share? My diagrams show a picture of the wires=
and works but no technical information as to the component specification=
s - which I need.
