Bigj66 Posted December 19, 2020 Share Posted December 19, 2020 What size are the brake pipe fittings for the S3 rear wheel cylinders? I thought they were 3/8 UNF but they won’t screw into the cylinder. Quote Link to comment Share on other sites More sharing options...

Bigj66 Posted December 19, 2020 Author Share Posted December 19, 2020 They are 3/16 👍 Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted December 19, 2020 Share Posted December 19, 2020 3/16 what? That's the normal pipe size, of course... But not likely to be the thread size, at about 5mm. Brake fittings were standardised to M10 in the early 80s/late 70s, otherwise they are 3/8 UNF. Quote Link to comment Share on other sites More sharing options...

I have M10 & 3/8 here and neither will screw into the cylinder. The 3/8 ones I have here may have the wrong tpi though. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted December 19, 2020 Share Posted December 19, 2020 That's for 3/16 pipe, not the thread size Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted December 19, 2020 Share Posted December 19, 2020 Brake fittings are pretty much standard across makes, even more so once M10 came in, I don't know what you have there, but if it is an imperial fitting, it should fit.....

The cylinders are rear axle 88” up to suffix E and came from Bearmach. If these new fittings don’t screw in either then I’ll need to look closer at them.

oneandtwo Posted December 20, 2020 Share Posted December 20, 2020 The wheel cylinders are always imperial on series land rovers - the metricification in 80/81 covered everything else on the brake system but the cylinders remained imperial. 1 Quote Link to comment Share on other sites More sharing options...
Cory Posted December 22, 2020 Share Posted December 22, 2020 My Series 2A has 3/8-24 brake fittings. I replaced and made all new 3/16" nickel-copper metal brake lines, too. Check out the website Fedhill Trading for Girling brake fittings info. Quote Link to comment Share on other sites More sharing options...
Bigj66 Posted December 22, 2020 Author Share Posted December 22, 2020 Well it’s all sorted now. I’ve no idea what was delivered to me the first time but they weren’t a 3/8 UNF. The second lot that I ordered from Bearmach are the correct ones. £6.25 for delivery for four small fittings is just ridiculous though. They were also delivered in an A4 sized Jiffy bag which was just wasteful and no doubt intended to justify the extortionate postage costs. The four fittings I bought only cost £2.96! It’s one of the downsides of ordering from Bearmach. 1 Quote Link to comment Share on other sites More sharing options...
Cory Posted December 23, 2020 Share Posted December 23, 2020 I agree. I asked about fitting sizes listed on their website. They said they do not know. If I can't order from the LR Part number. I do not order it. Since Fedhill was located in the USA it saved on shipping for me. Plus they list all the information about their fitting and other useful info. Bearmach is a minimum of $25 shipping to the USA. So I only order larger orders from them. Quote Link to comment Share on other sites More sharing options...
