No Name Series Resto

The S1 M/c's are available from the UK there are two types the early with 1/4" pipes & the latter with 3/16" pipes .
You can have the old one resleved & rebuilt for almost the same cost as the new ones but run the risk they will drill the porting incorrect . When I had mine resleved 30 odd years ago they did it wrong & drilled the port the wrong side of thr cup & which prevents the fluid entering the M/C . I know a number of people that have had this problem. My brothers M7 Jag has the same type of cylinder he had three done before he got one that worked.
You will have enough problem bleading the brakes without having the problem with a m/ c that hase been drilled wrong.l would advise buying a new one over a resleved one .
Well that is my 2 bobs worth.

When it comes time to bleed the brakes invest in a pressure bleeder it will save you a lot of time & hearake.

I heard that the Series I club was getting them made but hadn't found anyone selling them.
I can import the ones for 3/16" pipe but both ports are threaded right through rather than machined for the flared end of the pipe.
Sourcing direct from India they are cheap, just need a couple of fittings so that the pipes can be connected!

That is easy to fix. Flare seat with a copper washer underneath it. If you are lucky enough, you might be able to find a fitting to take a 1/4 flare. If not, change the to 3/16 when you replace the brake lines. Then you will either have to get new 3/16 size brake slaves, or get the flexible lines with appropriate ends to suit.

I personally would still get the original stainless sleeved. I can't see how the brake shop can drill the hole in the wrong spot. They bore it out and press in the sleeve. The holes can then be drilled in the correct location by drilling down through the threaded holes where the pipes connect.
