brake pads and motorbicycles
Hi I use almost exclusively Coaster rear and drum front now, because of the bikes I now build. Prior to this I used and built for others many coaster reay, and caliper front bikes. The caliper pads are so cheap, and so easy to replace, that you can carry them in your lil toolbag, and change them in the skdae of the convience store, while you have a nice cold soda.
Center Pull, or cantilevers have longer shoes (pads) better leverage, and more stopping power, these too are easy to change. They do require studs on the bike that none of my best early model american cruisers were built with.
A rear hand brake either gives you 2 levers on the left, or you can go with the rotary clutch handle (in stock) they work great, but take a little getting used to.
I NEVER use, promote, sell, or approve of the dual cable lever. This is because you are putting all of your eggs in one basket, and I don't know about you, but I don't want all of my "eggs" broken at the same time.
The potential problem with disk brake, and chain sprocket marriage is that it's very bad to have grease or oil on the disk pads, and few of us run a truly clean chain.......Possible, but I/ve not seen it.
Aditionally disk brakes are very new in the bicycles lifespan, and still rather expensive.
I am not a light rider, and have had no coaster braking failures on the run, but do relube them, and adjust the lash, or replace bearings as needed.
I hope this helps you, if you have any further questions please ask. I wrote you this as I was noticing that you were not getting detailed responses.
