Diagonally split brakes were introduced in the mid ‘60s and probably by the mid 70s most cars in the west were produced with this system. They are considered more safe. This car is 1986! My Mercedes W123 has diagonally separated brakes and it is older than the Spider!
Brake bleeding sequence is also affected by which system is used. So on the Spider you can bleed per axle. Technically there is no reason to starts at the rear or even find the longest brake line. Because the reservoir is split as well.
Although, some manufacturer specify very whacky bleeding sequences which do not make sense. (E.g. my Jaguar for instance. Nobody has been able to explain the sequence on my XJR, even the Jaguar specialist have no clue. They had no clue to start with, as they were not aware until I showed them the Jaguar workshop manual.

This is an aluminium wheel on a steel hub. So there is going to be galvanic corrosion. If you add copper to that mix it is going to be a whole lot worse!! Never use copper paste on aluminium wheels!!
The vaseline works as an insulator to some extent. These are machined flanges, so a very thin coat, evenly spread is required. Any water ingress is only capillary effect and the vaseline blocks that effectively. The vaseline stays surprisingly long in place. Wheels come off regularly .
Thanks for mentioning the ceramic based assembly pastes. I have some, but I rarely use them. I work mostly on old cars and most workshop manuals will mention copper paste, because that is the stuff in use when these cars where new. It did fine then, and it still does.
I know the limitation of copper grease (e.g. see above) but I am les familiar with assembly paste. There are a lot of them about advertised as general assembly paste. But I have a health distaste of stuff being advertised as “general" or worse “universal". Because it usually means it is average at best, mediocre at worse.
So unless I see it specifically mentioned by the respective manufacturer I stick to what I know will work best.

I use this paste in my work to prevent seizing of stainless steel fasteners due to galling and, in the assembly of shafts in gearboxes to prevent them from seizing to each other.

What kind of work do you do, if I may ask? Surprised to see any paste being used at all in these sort of applications? A stainless steel fastener on a gearbox shaft?
Did a few more odd jobs on the Spider. Getting everything ready for when the paravan comes back from Johan.
Although I had test my overhauled wiper motor and linkage, I had not run it with wipers on it yet. So I decided I better try that. I don’t want to have to remove the paravan again!!
So put the wipers back on and fastened them properly:
Got my wife’s plant mister to simulate rain in my garage. Wipers working fine.
Even did a little video:
So the problem with the interval is completely gone and it runs superb on normal and fast speed too!
I go the air intake ready to be mounted onto the paravan. Cleaned the edges:
As you see I made a very carefully little bed for the air intake. It is face down, so with the paint down! I don’t want any scratches. So there is a blanket, a paper and some workshop paper towels.
Note: When using news paper underneath (painted) car parts make sure you take the stables out!! They can scratch badly!!
Cleaned all the little bolts and washers. Also, fastened the little hose for the window spray system with some tie-wraps.
All done. I also touched up a few tiny spots of paint along the edge of the paravan and on the car. Like I mentioned, I do not want to have to take this paravan off again, ever!
