Any one tell me the thread size? I need to order some brake pipe nuts today, but don't have one to hand?

M10x1.0mm?

Thanks

I think the other size is the imperial equivalent - 3/8" unf rings a bell - possibly used on some american stuff like where imperial sizes are still common.

Ned.

yep, all "normal" brake fittings are either M10x1 (anything reasonably modern) and 3/8 unf (anything older or american)

Bear in mind though that 3/8 unf is not at all uncommon, if you are using girling twin single master cyls for a bias bar setup or using wilwood cyls then these are all 3/8 unf NOT metric!

incidentally the feed lines on the girling cyls use 7/16 unf threads, just worth pointing out while we're talking threads.

Saab clutch slave uses M12 x 1, again found the hard work way by me so thought I'd post it here!

Right....

I used the std brake pipe stuff.

The master cylinders are 3/8 UNF, so I put the correct flare to go with that sort of nut that I had. Its the difference between a square shoulder and a cone shape on the pipe end, ie so it fits the flare shape in the M/Cylinder or wheel cylinder etc. I have metric nuts at the wheel cylinder ends. I have done this for years when swapping parts around on my land Rovers, ie using later axles with Disc brakes, and hence metric threads.

Older British Cars will be mostly UNF thread, and newer and Foreign cars will be metric. (Basic Rule of thumb, but there are exceptions)

But then I am an Old Fart. and remember whan anything that was Metric, was considered new fangled and foreign

To add to the confusion some older british cars particularly some Morris Minors used 3/8" BSF.

Thanks, so the standard Sierra bits are all 10mmx1.0?

Dan

yep

how many do you need?
As i bought a tub of 50 and have a lot left over, can post them to you!

cheers Colin

Dan
