Not sure what you did.CJH wrote:
When I was reassembling and doing the initial adjustment, I did make sure that the handbrake handle was released, and I did tighten up the adjusters by hand until the drum was a 'light friction fit', but I think with hindsight that if the shoes weren't properly centred (and there's no way they could have been at that stage) then the light friction was probably from one edge of one shoe. I think I just didn't get the adjusters tight enough before diving in and tightening up the handbrake. And maybe that was compounded by not backing off the handbrake adjustment first.

Just half fit the drum, adjust the shoes so that both shoes are a just near touching at the top and bottom that will make sure the shoes are central.
