The Peugeot 406 rear drums have 195mm ID and the 944 drums have 190mm ID, it's not terribly far off. The heights are a bit different though with the 944 part being somewhat taller, 11mm.

Unsure of how the offset of machined-down 924 brake drums compares to the proper 944 hubs. If the brake rotor surfaces are further inboard using the 924 brake drum hubs than the 944 hubs then you might have a chance of making that setup work...

Working on my own version of this now.

My new front calipers are supposed to use a M10x1 Banjo but obviously the 924 front brake hose uses a M10x1 male straight fitting.

Since the thread is the same size, is there any reason I shouldn't just stick a copper washer on the end of the existing hose (assuming it's got enough of a flat for it) and join it directly?

Can't see a problem with it as long as it seals correctly and doesn't leak, to be on the safe side after it's done I would give it a thorough test before driving the car.

I have a bracket made up for the front caliper now in 1-inch x 1-3/4 inch 6082-T6 flat bar with M12 10.9 grade bolts...

The holes are a bit sloppy for the bolts (I don't have the capability to get more than 1mm tolerance, drill is worn out so the holes tend to not be really straight and thus have to be oversized) so I'm thinking the best way would be:

1. Line up the bracket to the steering knuckle by eye.
2. Bolt on the caliper loosely.
3. Check that the outer edge of the pad is reasonably following the disc (otherwise the bracket needs adjusted)
4. Pump the brake to make the caliper true to the disc
5. Tighten the bolts in position

It could still be misaligned if Porsche didn't machine the spindle surfaces square or if my aluminium block is not square or if the caliper mounting surfaces are not square but I don't really see any way to make that adjustable.
