I think it was Marcia S. But not sure. ("Marcia, Marcia,Marcia". - Brady bunch). But turns out I need to replace potentiometer in my wheel pedal.

Wheel accelerates fine, but when u left off pedal it will barely stop the start turning at a slow rate of speed.
It's not a name brand wheel, it's harbor freight wheel and no support or parts are available?

Where can I get this part?

Lou, in a Brent pedal there are 2 pots one for low speed and the other for high. There is a adjustment to balance on each of  these out, does your's have this feature? Could it be an adjustment?

Its probably out of adjustment like Wyndham mentioned.

I'm not real sure how HF has the wheel wired.

You may or may not find the adjustment screws in the foot pedal, In a regular DC power supply the high/ low adjustment pots are in with the power supply.

 

Hope that helps.

Look on the sides of that slide pot. There should be a resistance value (Ohms) listed.

 

Also, no matter the total Ohms value, it LIKELY is a what is known as a linear taper...... not an audio taper. That means that the total Ohms value (resistance) is spread out evenly over the physical travel distance. If the wiper is at 1/2 the travel... it is 1/2 the total Ohms.

 

Then call one of the places I listed and order one that matches or is as close a resistance and physical size match as possible. Solder it in and test it. As long as you are very close, you shouldn't fry anything.

 

best,
