Is my memory playing me up or, having stripped and split the caliper, doesn?t 
one fit pistons while it?s still split? (Just the once, as one splits the 
calipers, say, every 50 years.)

Hi Mike,
Installing those dust covers can be very difficult however with patience and 
liberal application of brake grease it can be achieved. 
First, as Greg mentioned it it imperative that both the grooves in the body are 
scrupulously clean. Scrape around with a dental pick to ensure that any rust is 
removed. 
Now insert the piston seal fully into the lower groove being sure to press it 
fully home with your thumbs. Apply a little brake grease to it.
Next insert the lower lip of the dust seal into the upper groove again being 
sure to press it fully home with your thumbs.
Now lightly  press the closed end of the greased piston against the dust seal 
and use a small wire hook to lift the outer lip of the dust seal onto the 
outside of the piston.
Now it will be possible to wiggle the piston  into the bore through both seals. 
DO NOT FORCE IT IN. LIGHT THUMB PRESSURE SHOULD BE ALL THAT IS REQUIRED. 
Finally use a dental pic to guide the outer lip of the dust seal into its 
groove in the piston. 
Only 3 to go...
