Yeah, I like that guy, Delboy. He shows lots of ways to do things when you don't necessarily have the "proper" manufacturer's tool. He also seems to do a lot of work on Triumphs. One of the first things I saw from him, I think, was how to clean the calipers. Before that I had never thought of it.
@1K9 I'm not sure (?) you necessarily need new pistons IF the rust is just on the tips where it contact the pads. The problem is when it is pitted where it would come in contact with the seal. If in doubt, get the kit with the pistons, but if once you clean them they look slick and shinny further back, you should be OK.
I just ordered a seal kit for the rear (already have the front), have brake fluid, and now just need some new shoes for the rear. It's hard to find rebuild kits in the US for the rear. This one I just ordered is from England, but with free shipping and will get here pretty quick....

Sounds like I'll see you in Maggie Valley. Yeah, good to have those brakes working in top form on the rides around here.
