Bendix 76 coaster brake guru needed for help and advice
Threaders:
Hi. I have just got a front and rear set of tuff gen 1's with a bendix coaster brake on the rear wheel. I have read lots of posts on here and on bmx museum, but none are adressing the issues I have with my wheel. I am a new member, so your sympathy is needed here please.
When I put the rear wheel on the frame without attaching the brake arm to the chainstay and roll it around, the brake arm rotates with the wheel. If I attach the brake arm to the chainstay, the wheel wont move, ie: the brake arm is tightened to the hub and wont move sepeartley from the wheel. This isnt right is it?? Also the freewheel wont move seperate from the wheel also. I am guessing that the frewheel shouldnt move forward and maybe not move backwards either, but you should be able to coast. In which case the frewheel sould stay stationary whilst the wheel moves when your not peddaling if I am right.
All the parts seem to be there although I havent taken it apart yet so I am basically asking advice on what the problems might be. I have seen many posts with pics on re assembaly of these hubs but am a little tentative of taking one apart if it is not needed.
I would rather keep the coaster brake, but if its going to be a headache, then I know allansbmx still have the jb freewheel converters. would this be an easier option and do I need to buy another freewheel as well as the converter??
I have attached pics below of what I have .
I really would appreciate any help I rang round local bike shops, but no one can help. I also would like to thank everyone on here who I have bought things from. Cheers ;) :) :) Ps, I will need things explaining in laymans terms if possible. Ta.

Sounds like it needs stripping, cleaning and re-greasing. Very straight forward and anyone who knows how to use a spanner can do it. Read this site http://www.sheldonbrown.com/coaster-brakes.html for the low down on how to it. Bookmark the site too as it is SO helpful on anything else bike related :daumenhoch:.

yeah sounds like that, or it could just be too tight, try and loosen arm side lock nut a bit, without making wheel wobbly
If not need to take complete hub out and clean, regrease. check cones etc for wear.
NOTE - the cones etc will drop out so make sure you note how they sat in the hub.
its common for these to lock up ive done a couple of them

Thanks for your advice. I was hoping to avoid stripping, but if thats the way to go, then I will do it. I will post pics on here of my progress as now doubt stripping will raise further issues. Check the post tomorow to see what a mess I get into :laugh: :laugh: :laugh: Thanks again for your help, Jonathan.

Forgot to ask can you recomend a type of grease to use. I have heard it has to be high temp so any product advice would be cool. Thanks
