Disc brake on D-300
#1
OWhat kind of disc brake was used on the Rupp D-300? 
Found what I think is a '67 or '68 and curious if the brake would be satisfactory. 
Would probably run a Clinton on it. 
Thanks

Art,
That sounds like it. Do you know who made it? How well does it work? Thanks

The D-300 I believe came with the 6" Bendix drum brake or equivalent. Usually had a 4-cycle engine sold with the kart. I think a Clinton (2-cycle) would be fine. Model was sold for a lot of years under Rupp Manufacturing, then robron, Inc.

3D Images. BOTH karts shown are D-300s one is a 71 (background), 72 (individual). Being younger vintage kart owners, these guys upped the power to get some more GO, however, their karts had the 6" Bendix brake.

Thanks. Great pics. Do either of you remember if the D300 had a 1/2" or 5/8" steering shaft?
This one has the Dart steering wheel.

I bought em with both brake styles. The bendix brake would be better in my opinion than the mechanical disc. I took of the cheapie disc brake off and put the bendix on my 300 , also cut the fixed motor mount off to put a swing mount on. Just that and get the wire type pedals and you have an Abone with no real work or money spent.

Mine as the mechanical disc.   But it's a project kart and I haven't driven it to see how effective it is.
