1/4" to 3/16" Brake Line Adaptor

[rtcosic]

My car has 1/4" brake lines.
I am fitting a servo with 3/16" fittings.

Google shows me plenty of 1/4" to 3/16" adaptors but exclusively from US suppliers.

Surely these are available in the UK?
Am I just failing to enter the correct search terms?
Would it be more likely to get some from a local factors?

I bought something similar many years ago to fit modern (metric) M16 brake calipers to a British classic (originally with imperial fittings).
Not difficult to find then in the UK, things may have changed since.
Maybe try RallyDesign or Burtons ?

Burtons

Can you help me out with that.
Mrs Google sends me off to menswear, biscuit makers and veterinary equipment suppliers.

I'm chasing down Rally Design, Merlin, Beales and all the usual suspects.

The Carbuilderssolutions website lists the adaptors along with loads of useful stuff , not the cheapest but they always try to have everything in stock

Thanks all - several promising sources to follow up.

My next challenge. The car is all BSF.

Is the 1/4" brake line likely to have 7/16" UNF or BSF on brake master cylinder and tee?

Carbuilder Solutions only non UNF option is 1/4 BSP.

Any easy way to determine this without undoing a fitting and offering up a thread gauge? I would prefer to have all the parts to hand before I disable the brakes.

What car is it? My Morris 8 is BSF on brake lines. It may depend on whether it has Girling or Lockheed brakes. iirc, Girling stuck with BSF for sometime before coming into line with Lockheed.

1951 Alvis TA21.
Handbook says Lockheed drums so presumably the master cylinder is Lockheed too.

Then my money would be on UNF.

Just a thought, would perhaps just whipping out a bleed nipple to check be an option?

I've postponed the activity to another weekend to have time to confirm with the club 'expert' - hopefully.

Why is it never straightforward!

Admitted defeat and removed the short length of brake line.
It's 7/16 UNF and thanks to members I have several sources for the two adaptors for 7/16 to 3/8 UNF.
