Rear Brake 11/23/13

In order to ride the Cannonball 14 safely I felt I needed a second brake and preferably a front brake. I spent a considerable amount of time talking with people and measuring every front brake I saw at Rhinebeck. I did not see anything that would fit and look good on a Henderson. I spoke with Kent Thompson and he said his plan for his bike is to use the internal brake with a hand brake lever versus the right heel brake pedal. This made a great deal of sense. I would have a second brake operated with the hand brake lever to make starts on an incline manageable.

I showed up with my parts. The goal is to make the parts for the internal expanding brake. This was an option and impossible to find parts.

here is the brake plate after we honed it for a new brake cam bushing

We put a shoulder on the bushing

Next is the outer contracting band

I used new outer band material. My original band was beyond shot. So all these pieces came off the original and riveted on the new band

Rivet this piece on. All these pieces are different than the standard external brake band.

Next is the outer band. I had already cleaned up all the parts and riveted the top piece on. At his shop we then drilled and riveted the two bottom brackets that hold it all together

Now the internal expanding band. I had bored the hole in the band and made the post. Pierce showed me how to adjust and fit it better. It is seated, peened and silver soldered

Next we fit and riveted the two feet on the end of the bands. Once they were in we milled the two faces parallel

Then we fit the two eye bolts to the band, drilled peened and silver soldered

here it is

Man, that looks so COOL

here it is in place.

This sure looks great

Here it is with the outer band on it.

And, here it is with the brake drum in place. The next step is to temporarily attach the brake band material and fit it on the bike.
