What are the two small white wires for on most wheelchair motors?

Summit Law

I am wanting to use wheelchair motors to pull a remote control lawn mower up hills and through ditches. I bought a used wheelchair and even drove it around to make sure the motors worked before I took it all apart. Electric motors normally have a positive and negative power input. However, these motors have two small white wires also. What are they for? And, do I need to use them for anything?

Answer
It could be for a shaft brake. You would energize the two white wires and an internal solenoid would pull back a brake pad or lock pin and allow the shaft to turn. This would keep the wheelchair from moving further once the user stops it or releases the control.

I have rear engine Snapper riding lawn mower and had got grease or oil on my drive plate. I cleaned it off with gasoline really good but the drive disk/wheel still seems to be losing traction when I go in reverse or up a hill. What can I clean the drive plate with to increase the drive disk to drive plate traction?
