A big word of caution.
Be VERY careful about which type of front drum brake you use this conversion on. Certainly series 1 and 2 machines have a back plate where the location for the link peg is not supported.
I have personally seen two of these back plates fail (even with standard brake arms). The back plate location broke where the link peg fits. The result was the back plate broke lose from the fork link and wraped itself, speedo and break cable around the front axel sending the pilot on a one-way trip over the handlebars and face planting the tarmac.
Always use the later back plate which has a small triangular brace to support this area, it is a lot stronger.

....so a fist full of hydraulic in an emergency stop is the solution...?
thanks for the praise Tony...
quoting on above.. the danger is only when the shoes are badly worn and porly adjusted and the cam locks....

Like with any brake that works you will always need to be cautious on slippery surfaces, I've had the standard hydraulic brake on my GTS lock up at 30 mph on a wet London road, I tend to only use 2 fingers on the brake lever now.

no thankyou joey, while wheelying around the bus station in my tracky and doing front end slides to the kerb edge i was attracting admiring glances from 16 year old girls in tight leggings, top evening. :baddevil:

Make sure it's the thicker version which was standard on disk brake lambrettas since that is much sturdier and wont extend during braking. Scooter restorations sell it for about £4.

Second that - the distance pulled is the same from both ways.
You will "become stronger" and thus might be able to pull it "over the edge", but with ok shoes and everything setup correctly this will not happen.
Finally diving wont affect the pulling.

A video of your claims Al Caholic would be good, endos on a Lambretta drum while attracting nubile young things. That would be something to see.

That looks smashing, cheers.
I will be trying that on my series 1 (series 3 front hub). Hope to soon be doing 55mph stoppies on the dual carriageway on my ride to work.
Reckon your shoes would have to be well worn to jam em on. This could happen if the brake was cabled up the regular way and you pulled like Geoff Capes too eh? But worth bearing in mind though, for sure.
