Rear disc conversion

[400 Cafe Racer]

Lovely chubley






Happy with that

Will need to make up the required wheel spacers nearer the time that will replace the round black and white areas you see at the moment

All really that is left to do is sort out a torque arm that fits between that hole in the hanger and the original fixed pint on the swing arm and improve the hub locking assembly as per the earlier post this morning which I see as a no brainier

As the wheel assembly design is almost complete and looks totally practical and all the main problems are solved I will next look to see how I can sort the rearsets to accept a master cylinder which will need my thinking cap on as it will need to look pleasing / factory like the rear disc assembly

Hope all are enjoying the posts so far

Hi Allan,

I've just caught up with the progress on your disc brake conversion, some lovely work going on there, nicely finished.

Looking at the mounting position of the underslung caliper, I just wondered what your thoughts are on potential water soaking of the pads from spray coming off the front wheel, it looks as though it could be in the line of fire. ?

What do you think ?

Regards

Dennis

Yes I see what you mean, the set up is the roughly the same as the Cagiva Mito that I have copied that has a under slung caliper too.

Maybe slight lower but still under slung

Worse if it was an issue I could always add a subtle 3 d printed “deflector” mounted on my lower exhaust mount that sat in front of the caliper for extra protection from spray if I ever go out in the rain

Lastly pads are well hidden / shrouded inside the caliper due to it being an opposed piston unit rather than a sliding type with minimal gap for the disc thru the caliper body (about 1mm per side clearance between disc and caliper body)

" if I ever go out in the rain"

Yes I know what you mean. !!!

The Delkevic looks very interesting.  Do you have any video footage so we can all hear that "music" through the rev range with the 400f on song. ??

The 3d printer you are using is giving really good results, can I ask what model it is and approx cost of running it?

Hi Oddjob

I am a greedy person

I have three in total, two ultimaker  2’s and bought my son last Xmas a Flashforge creator pro 2 that I borrow now and then (plus jump on his pc that has  Fusion 360  when I cannot use my SolidWorks pc)

The ultimakers tend to get used for big stuff like the disc carrier and my rd sale parts like replacement clock cases







and the flashforge for smaller stuff like the rear set stuff



And some nice dual extrusion/ colour parts too in ABS as the flash forge is good for fine detailed parts due to it using a smaller nozzle and filament and has a more controlled filament feed system




As for running costs,  other than upfront purchase and a few maintenance parts they run for free and at a good profit as they are always on the go making parts for eBay / FB and the Rd forums as shown below as a little home business as well as home projects too like the disc conversion

Hi Dennis

Yes the Delkevic is a nice stainless system pipe and much cheaper than a yoshi pipe and British made







As for the sound

“Hear” you go

Not great videos but these two show how to be anti social

Well the little Honda is a stable mate to a hooligan RD350LC

Hi Al,

Thanks for the "music" of the Delkevic. It sounds like a nice balance, not too obtrusive while cruising and releasing the full throaty character of the 400 Four on acceleration and upper rev band. Its the first chance I've had to hear the Delkevic on the 400 Four.

Cheers, much appreciated.

No problem and glad you like

Even the darling wife thinks it sounds awesome and prefers it to the RD

Hi Oddjob

There a a few free 3d packages out there and I think you can get Autodesk as a free trial package and if you have a “sibling” in full time education you can get the full package as a student for all the time they are in full time education as I did with Logan also as he now has an account once he leaves full time education he can get a license with up to 75% discount

Also it’s easy to learn and once you understand the principles of how a model is created you are away

For the flash forge don’t forget this is a dual unit thats a bit more pricy but all printers run free downloaded “slicer” software so the real outlay is the printer and a decent pc

Yes I believe you can but I tend to measure and model up the original part and save it then modify the model after

If you are after sometime I would be willling to help out but as it a home hobby things do take time

Also don’t forget most time I am limited to only smaller items and my disc carrier was at my printers limit for size

Feel free to pm me if you want

Ok back to topic

Just bought this

After a chat to the real “boss” an early Xmas prezzy for the rear disc conversion project

Original Dresda box swing arm (hence my other thread on interchangeability for swing arms)




Will need a bit of TLC but another non standard part for the old girl and will go well with the rear disc conversion

Only problem is this bike modification process has now started to become an obsession

Also now got my hose from Venhill so should be able to test fit this too to see if I got my hose length right

Catch up again soon and all have a good week

Best wishes and ride safe Al
