My horn brush was really worn where it rides on the ring. I took it down to the hardware store and picked up a round brush that was a slightly smaller diameter. I trimmed the brush to length, hooked it up to a spring from a pen. Put it in and it works great. The carbon brushes are very soft, easy to cut and mold to shape.
By "brush" what type of brush do you mean? Metal brush (like for polishing)? Paint brush? ANy recommendation as to which brush and spring? Thanks in advance.
A brush for an electric motor. Ace Hardware has a bin full of random sizes. I got one that was a cylinder but just a bit to big around and to long. Easy to re-shape/cut to length.
There are a couple other key bits you must have for the old horn to work.
