I think I may do that. my ring compressor has a slightly too coarse ratchet to get tight enough but we'll give it a go. Renault definitely recommends in their factory manual to insert pistons from below on the 1647, 1565 and 1472 cc engines...FWIW
Not sure if I'm trying to tell you how to suck eggs - but here goes. My experience of Peugeot brakes, limited to 203, is that being Lockheed they follow imperial dimensions - lines cylinders et al. However, unions are metric. Accordingly I was able to use an imperial double flare kit to make up the lines with 1/4" pipe. I'm not sure if the same applies to the 404. There is a metric standard flare kit available. It may have a different angle on the flaring tool. Which one are you using? Are the 404 lines 1/4" or 6mm?I never did get the image of the taper type ring compressor....
Anyway after a bit of a layoff due to being busy cycling and then about 4 weeks ago, a knee injury, I had a go at making some more brake lines to see if I could get the new ones to seal.
To recapitulate, I bought some 10 mm unions out of Der Franzose, thinking that they'd be better than the ones I bought locally (which were non-metric on the wrench site, threading is the same). Noticed on a couple of practise flares that the shape of the union at the contact point is very different: the dirty union is a factory original; the longer union is the locally sourced one; and the short shiny one is the Franzose union.
The original and the local one have a very different taper where the flare is pinched against the cylinder - definitely incorrect!
Does anyone know where to get properly tapered 10 mm short unions?

Yes and a friend in the Netherlands told me it's from a Peugeot J7! It's a nice piece.Windscreen washer jet?
