Braking on the Barclay is a bit limited. We get some rear shoes and nothing in the middle. Is this prototypical?
Anyway, the whole lot hangs together OK with everything attached to wires poking from the chassis. I did wonder if the operating gear would look better if the oval cam thingy pointed down rather than up as the instructions show. There's little in it, so I followed the manufacturer. Most of this is hidden behind the back steps anyway.
The brake shoes are plain so I bent some square plastic strip and superglued it in place. Then I filed it back a bit to reduce the thickness. I could have used thinner plastic but it's easier to bend a square cross section without it buckling.
