Brake line Metric VS imperial
Dear all,
The atom is still coming along!
Silently, but still…
Now
Those following the build know I have a Saab 93 Master cylinder and MGF uprights/brakes
It works in theory…
But actually the Saab is metric
And the MGF imperial.
I measured up the lines and I think
the saab is a 5mm brake line and a 10mm nipple, the MGF a 4,76mm and euh ?nipple?... Correct?
Now can I get adapters from the one to the other?
Or can I get thread cutting sets to make one ?
thanks !!

Pretty sure the MGF is metric? pretty close to imperial, think it is 10x1mm thread?
Brake pipes are usually 3/16"

Really? than I missed 
But 3/16" are imperial brake lines, so metric m10*1 nipples (couplings) on an imperial brake pipe ?
It's quite hard as the lines are coated or crusty...
difference between 5mm en 4.7625mm (3/16) is only so small.

3/16 used on all cars I have owned, old and new (ish, modern cars don't need brake pipes after 6 years like they used to!)
Bit like all seat belt bolts being 7/16UNF thread, the world over.

All modern brake pipe (with the exception of master cylinder to ABS unit) is same bore it is an SAE spec adopted by DIN. The outer diameter of the
pipe varies, MG-Rover used plastic coated pipe SAAB used Kunifer at prior to GM downgrade.
Both cars are metric.

Yep! They work fine, most brake flaring tools seem to be Imperial.

Most modern ones are metric .
Using a mix of imperial and metric pipe is a bit of a bodge but it works. If it's Good enough for Rolls Royce its's good enough for me
.Silver Shadow at least

I'm just renewing several pipes on the Trans(h)it, which the MoT man was not happy about (and quite rightly too). It's a 2002, the most
modern thing I've ever had. Metric steel 10mm fittings (13mm head size) and steel pipe originally fitted, now metric steel 10mm fittings (11mm
head size) and 3/16" Kunifer pipe mixture.
Retest next week.

you where most right...
MGF indeed has metric M10*1 on 3/16 pipe...
Saab has it too, except for 3/19pipe with M12 fittings from the brake master to ABS
