brake facts...
 

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

Bob:)

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.:)
