Technical Brake Difference

Typical drum brakes are a drum with with brake lining on shoes, What if the lining was on the ID of drum and the shoes were plain metal? Difference in braking ability?

 

They would fade really fast, the drum is a better heat sink.

 

I would think it would be harder for the waste wear material to be removed during operation as well.

 

See how it works is. The train leaves not the station.

 

Did you ever try to stop a truck using the transmission mounted band type parking brake?

 

Where would the heat go?

 

No never had a truck with band parking brake. Don't think the same, band brakes can be very self energizing.

 

No gearing involved when brakeing at the wheels. That said, when I was in wood working we had a 48” wide 3 drum sander. Each drum had it’s own band brake. That thing would stop those drums in a heart beat.

 

I realize Seb is just thinking outside the box, but with lining on the drum, it’s possible it would have a balance issue.
The lining would still need to be replaceable as would the “shoe “ metal. And probably thicker material as well.
Seems like a complex way for a drum brake setup to work.

 

Probably minimal and momentary advantage. Once some heat builds up there will be a marked loss in braking ability.
Cost of wear parts, design challenges mounting lining materials to drums

 

It would work better if the friction material is on the side of the drum, and to prevent flex put more friction material on the other side to get clamping loads working against each other

Come to think about it, I just described a disc brake

 

Back and I mean way back when I didn't shave yet there were drum brake setups for racing that used brass blocks for the friction material. I'm pretty sure it was a race car / circle track only thing and I don't know how long the use lasted if it lasted very long.
All I can find right now are brass brake pads compatible with Honda. Amazon.com: Brass Brake Pads (1 Pair) compatible with Honda 06431-HL4-A01, 06432-HL4-A01, 06431-HL6-A01, 06432-HL6-A01 : Automotive

 

One of the aircraft I used to work on had brakes designed like this which were cable operated. They worked, sort of, but the Cadet only weighed about 1100 lbs. so even though marginal they would slow the airplane down. But you really had to stand on the pedals to do so...

 

Kinmont brakes?

 

No. Train = drum and station = shoe’s.

 

In kinmont brakes the lining rotates. So train stays and station leaves? https://video.search.yahoo.com/yhs/search?fr=yhs-iba-1&ei=UTF-8&hsimp=yhs-1&hspart=iba&param1=RypDRDjp20T5Vc76fVk9yA==&param2=9dUI1n2R0BLDxNuWfiP4aSFOTltNdSPoIx38+Uf/iXrvPdoGmStdlfwLFZYDvqkAJrWWk4yNReCLnBD/qPsDZd7olTZcV8HMx1G/k786sE2Tis1g8dJd8zxVWs+bKztBnq1TfqUiqPYK9pXifXmJFyorDuCsYXJE71Y6G5tfejC6ZiJFvbOkkuNg81MboqK8SYFWvjG2ogWG2qx4NOjYO3B96v1Bh5bca323E6bjWScQya7BvpBHPNZAAMREljLjRNXlR3E3PIhTKd23bdRJ1u6aYiHDxJrbygzss6FkgO7xOfW2YxDIG7KJmcFLrYmq&param3=NwVEMR/zKcG52XsVBYEh2+7y7tP1R8GKaAIj3YL4xdd/E5efLaBeRWtz/6/JStiLqcinhjFb3AsRYIGqTwSGLpXvEkbK3+jWaNWzizH0nAyD2wFKdOg4FSu/EBh5qoAGGW7FNHUQf/pjezenkB19DWRHUHe2Qym0ouuEV4JMedZU5ZriN4A7Hs6i71hGP+RlKnvM030VMlK5T/d3aTZ1yaj1fgcTUviyqUTlHYJ5Y8n74lITPzxe976UjAOA6Ck9tNYVvLc/wZxaoWPq4FOIgjxHQKSWTreD3zHA+mqrYUNQDPTt+iLJF+ZSk1icZFHdTnxLKFvvJKKeLIr2u9cpwqglcvHrOcrnifj+S9mtpX3BhckORrarOdtn6gmyuggpShI7ePG3uibrwy336kFc+bBpWz3v4pm/Z+KpiLLY4UINIovQfiOhykvXbrpiN0ooIYSttqNeQNPfPaCec1Ag7g==&param4=NcXv6J+Aa4MfOtnXbc2hil9Vmt8Hn+2MliIt3WnJEgM=&p=kinmont+disc+brakes&type=w1pr_5056_CHW_US#id=1&vid=e9f71fe6977de89638cbc58e738a53ad&action=view And Chrysler https://video.search.yahoo.com/yhs/...=5ee9e140b1350fcc2b9007a7af606907&action=view
