If you are really chasing performance then perhaps.
The brake upgrade I would be interested in is ABS. It is fairly easy to lock the wheels with standard brakes let alone upgrades. Perhaps a brake bias valve to fine tune front/rear braking as well?


Alloy drums are about heat dissipation to avoid brake fade. As indeed are discs. Spirited road driving particularly with long down hills can give brake fade
Yea, but how many people experience this in normal use.

I never have and believe Me I have driven very fast on very long down hill roads. You can not do much travelling in the Rockies without a 5,000'+ drop from 10,000'+ to 5,000'-. I would expect the Swiss Alps would be the same.

Never the less adding an aluminum fin to a cast iron brake drum sounds fascinating, just to do it.

Similar conditions in the French Alps and Austrian mountains. The motor-brake is a secret not all flat-land-drivers have discovered...

I seem to recall that the Alfin barrels on my Velocettes were made in a similar fashion with the alloy outer 'bonded' onto a steel liner. They were known to distort but I never had any problems on any of mine. It did cause a bit of head scratching by the old boy that rebored my '47 Cammy Velo barrel though. An expansion test of the unknown piston was achieved with a plumbers blowtorch and a ruler! I renewed the small end in situ and a degree of guesswork was needed on the clearance to gugdeon , still must have been about right as I put several thousand miles on it before I sold it and it's still going strong with the new owner.

Back to brake drums, some are balanced which would be removed by the machining so would need rebalancing, the ones on the Healey are renowned for balance issues that cause significant vibration if not done.

Did you have a Mk8 KTT or a Mk 2 KSS?

The only reason I ask is my 1947 KSS has an iron barrel!

I hasve. Going down Porlock hill for example. Hence the old style advice to engage low gear.

Alas it was the less exotic Mk2 KSS, only saw one other with an alloy barrel, maybe a go faster option in its day? Also I fitted a belt primary, not really worth it in the end..

Bonny looking bike Steve! Mines currently in large pieces awaiting reassembly - treated it to a new big end and rebore. Also needed to re bush and straighten the forks. Will get round to reassembly shortly!
