I think it best to first wait for the bleeding to stop.

The ones on my Triumph work as well as the twin disks on my R65. Of course the disks are stopping more weight.

I've commented before that I actually prefer the feel of a drum brake on the rear for street applications, but I love modern discs on the front.

Referring to front brakes:

Most early discs suck compared to the best drums from the same period.

Almost all modern discs are far superior to even the best 50 year old drum designs.

It would be really interesting to see what a modern drum design could do against modern discs. There's no reason why a modern drum couldn't be hydraulic, which would allow it to be ABS.

And then we are back to the bloody bleeding!

All I see is ruined paint and fluid hydroscopicised.

These feet were made for walkin'.

I like drum brakes on the back because of simplicity and because they do the job. Whether powerful drum brakes on the front would suit all riders is less certain. Drum brakes and especially twin leading shoe drum brake could be prone to grabbing because of the self servo effect of the leading shoe. They are generally more fussy than discs to set up and anything that changed the dimensions e.g. thermal expansion could impact on the way the shoes contacted the drum. Better than disc in the wet though

I have only one airhead with a disc rear brake. It works much better than all the drums I have. I don't actually mind having a rear brake that works. In fact, I like it.
