Just so I've got this right, Sierra brake lines are 3/16 but with a metric M10 1.0 fitting on the ends right? Seems an odd combo of imperial and metric...

Also, any reasons not to salvage the pipe fittings from the donor and use them with new pipework?

Yes that is correct.
1 reason is new ones are so cheap it would be idiotic to trust a second hand part that is over 20 years old sat in all the road grime and salt with your life.

Said in the nicest of ways :D

The pipe size thing in imperial will probably be here for ever. Can you imagine the confusion if they brought in 5mm brake pipe. Its the same with tyres on imperial rim diameters with metric widths. Sheet material is still imperial in width and metric length. Or is it the other way round:confused: :)

*Shrug*, the diameter of 4.8 mm looks metric enough to me! ;)

Brake line fittings cost just a bit more than normal nuts and bolts, you'd spend just around £5 for all new shiny fittings. So, same reason why you use new bolts where you can.

4.74mm sounds a bit less metric :p

Getting you loud and clear :-D I only asked as when I took the master cylinder out they basically looked spotless!

My brake flairing set has a 4.8 mm die, the lines I bougt were ⌀4.8. You can call it 3/16" if you want, but 4.8 mm is a proper metric equivalent.

Decimalisation and metrication was forced upon us by Europe,does not mean we have to like it.:p

Feel free to call me 'Noddy' but would something like this be a perfect buy for a Roadster brake installation?

I dont think metric will ever be totally embraced. the yanks for one dont seem keen to give up the gallons,miles,feet and inches,pounds ,stones etc , there are dozens of other countries happy to stay imperial.:)

Pratchett & Gaiman said it best:

NOTE FOR YOUNG PEOPLE AND AMERICANS: One shilling = Five Pee. It helps to understand the antique finances of the Witchfinder Army if you know the original British monetary system:

Two farthings = One Ha'penny. Two ha'pennies = One Penny. Three pennies = A Thrupenny Bit. Two Thrupences = A Sixpence. Two Sixpences = One Shilling, or Bob. Two Bob = A Florin. One Florin and One Sixpence = Half a Crown. Four Half Crowns = Ten Bob Note. Two Ten Bob Notes = One Pound (or 240 pennies). One Pound and One Shilling = One Guinea.

The British resisted decimalized currency for a long time because they thought it was too complicated.

I think we are really lucky in this country:)

Elsewhere in the world children have to learn a foreign language from a very early age:o

Weird that everyone thinks that our 12 pennys to the shilling and 240 pennys to the pound was odd. Makes you wonder why if it was that bad we have not ended up with 10/20 hours a day . No one in the uk at the time had any problems at all working the uk currency in the same way no one has trouble with the 12/24 hour clock:p :p Also weird that formula 1 cars are still littered with unf/unc threads. As said before it will be many many years if ever before imperial measurements disappear.

And for all you unfortunates that remember,every thing doubled in cost,who in their right mind would pay "10 bob" for a Mars Bar.

4 Fruit Salad or Black Jacks for 1 old penny,what has the world come to.

Objectively, the benefit of the 12-base system is that everything is divisible by 2, 3, 4, 6. On the other hand, we memorise 10-base multiplication table in the primary school, 12-base one would be larger almost by half.

That said, time and calendar is the weirdest measuring system of all, even before you take leap seconds, timezones and and daylight savings into account.

How right that is:) A few years ago we were in a chip shop and the guy handed my mate a bag of chips and said that will be 75p, my mate took a step back and shouted you robbing B@stards how can a bag of chips be 17 and sixpence:) :) .

Alga stop sleeping on top of an encyclopedia you are soaking to much of this stuff in :)

Yes, this looks just the ticket. You might need more male fittings, and 2 T-pieces, and probably M10x1 locknuts, but this is a start.

No, actually on my car I used 6 female and 10 male unions.
