Ok, I think found it, it is this one:

I phoned an official Piaggio reseller just now and it sadly confirms that part does not exists anymore. But, you may be lucky: if you are willing to share the exact measures of the one you dismounted I'll call again and will let you know if there is something that fits/replaces that one.

Hope this helps.

"I've checked the manual and I cannot find any adjustment mechanism on the rear brakes, which is strange as hub brakes normally have a automatic mechanism which you have to let-off before removing the hub. New shoes have been ordered so that will be a job for later!"

Automatic? You must be working on newer fancy brakes! I was used to adjusting the drum brakes with a screwdriver and sheer luck that I was rotating the adjuster the right way, in what today would be the equivalent of trying to insert a USB device, but with far more frustration.

The missing parts are out there somewhere, just have to either search harder, or find whether that part may have been used with other Vespa models and find it that way.

Still envious of your closer reach to accessing spare parts. :)

A lot has happened over the last few weeks F<)

Smallwood Vintage Rally - https://www.smallwoodvintagerally.co.uk
The Ape went to it's first show just down the road from where I live, it's the first time I have been and it was a lot bigger than I thought! There were lots and lots of vintage tractors, cars, buses, steam engines, steam trucks, vintage caravans, well worth a visit next year.

First job trailer the Ape Cornuto2

I used a lighting board on the rear of the trailer as I still need to finish modifying the trailer for the Ape.

The Ape was put in the 'Light Commercial' section of the rally, just after I took this picture a Pontiac parked behind the Ape and completely dwarfed it!

Since we were staying at the Vintage Rally overnight in my wife's vintage caravan I didn't want the Ape to get rained on so I parked the Ape in the caravans awning C-; You could easily fit two Ape's in there!

On the Saturday I was going to join the commercial vehicles in the arena, however, the Ape refused to start, after an hour I gave up. Later that evening I tried again, did my basic checks, fuel - yes, spark - no!, turns out I had a faulty spark plug, luckily some of the trade stalls were still open and I found a new spark plug - it then started first time!!!

On Sunday I join the commercial vehicles in the arena, the commentator said that he had never seen an Ape before and referred to the engine as a lawn mower engine :((

I will post another update about the rear brakes soon

Rear brakes

I ordered some rear brake shoes from Juergen Kamm.GaLabau@t-online.de £54.00
IMG_8433.jpg
These are unbranded, the 'meat' on the shoes is 7mm thick.

The old pads below still had meat on them, about 4mm, but it looks like there are three different brands of pad on the rear, if you look at the left set one shoe has three 'humps' in the metal.
IMG_8451.jpg
And the left set is different from the right!
IMG_8452.jpg
Changing the shoes improved the braking however it still left two problems....

1) The handbrake still didn't work!
As I have read on other posts the handbrake didn't work even when adjusted, the handbrake could be pulled all the way but the wheels would still turn. I happen to see a post on another website which mentioned that the 'bar' which operates the brake shoes when the lever is pulled gets worn over time and therefor doesn't 'push' the shoes with sufficient force. The measurement should be 7.5mm.

This is the o/s
IMG_8443.jpg
and the n/s
IMG_8450.jpg
This one was also bent!
IMG_8449.jpg
As you can see the 'v' shape is 3.5mm longer than it should be in addition to this the other end was also worn on both sides
IMG_8442.jpg
To fix this I used a bit of weld to fill in the damaged metal then filed it back to make the correct shape
IMG_8444.jpg
IMG_8445.jpg
Once assembled it fixed the issue with the handbrake Cornuto2
IMG_8446.jpg
2) The n/s rear brake is binding when the wheel is turned.
I noticed that when the n/s rear wheel is turn the brakes bind at points, I need to do further work on this to investigate the problem but as I have rebuild the brakes several times I know they are assembled correctly. I will post my findings.
