Front Coaster Brake Mad Scientist Crazy (wear a helmet)

[Jim H]

In retrospect, that could really jam you up! I'm still thinking on it dog...

 

[gone_fishin]

it's very simple to do, now that i understand how to block travel. all i have to do is put a large washer (proper thickness) over the threaded part of the driver. done deal.

this project will be completed, it's too close to not be. don has another motoredbiker (another not-member) friend who wants to try. i'll get pics and info whenever something happens.

i'm not gonna mess around with it right now...i'm not one to tempt fate too much

What about mounting the coaster brake in the front forks as you would for a rear wheel and using a short length of chain to rotate the sprocket. One end of the chain is connected to the brake cable, the other end to a spring which draws it back.

Anyone have any thoughts about my suggestion? When I get a moment I'll strap it altogether on a spare Raleigh frame and see how it goes.

I can't remember where, but I've seen it done on a rear wheel on a build that had no drive pedals (It did have a brake pedal). I wonder about how much pressure it would take to actuate.

Yup, that was the guy in Maine I believe that is running a Honda with no pedals. He had the direct drive with tensioner clutch. Can't find the post.

Ah yes, it was Scrollerguy, and you had a link to the plans he probly used. Anyway, if there isn't a leverage problem, I don't see why it wouldn't work.

Front coaster brake

Hi all. a couple of weeks ago I went thru, cleaning and regreasing of a Bendix Front coaster, loaded into a 24" Worksman wheel off of a Schwinn Whizzer.
It was Quenton who told me that brake assembly is worth 300-400.00. This is the second one I've seen, both on Vintage Whizzer bikes.

This brake did NOT have the 2 shoes, it had a series of plates inside, like a multiple wet-plate motorcycle clutch. I should check some of my old Bendix rear hubs and see if they are built that same way.

I'm sure glad for his sake, that all the bearings and races were good!

I have not yet had a chance to ride that Whizzer, but I think I'll see it running soon (Customer's bike).

I had a dig about in the 'stores' in my workshop this afternoon and I'm pretty sure I can put together a test mule bicycle to try out a coaster brake on the front. If it doesn't work I'll just unbolt it all and put the parts away again.

Mike, I'm reasonably sure that a rear Bendix brake has plates too.
