Nurse Julie:
Try 400 four bits. If you can't see what you are looking for, email Steve and ask, he is a very helpful chap.

Yeehaw I've finally got the front brake working. I fitted a service kit to the spare, I think original, master cylinder. Now I have to tap in a new thread as I have removed the broken mirror stem by drilling most of it out. Could someone tell me what tap I need? Have sourced a clutch casing from 400 four bits. I'm concerned about what the thread might be like in the crankcase but that's for another time. Whilst idly moving the right footrest up and down as it is removed, it was clicking up and down nicely with a click in and out of the up position when suddenly it went floppy, I didn't see anything ping off anywhere but that's not to say anything didn't. Does anyone have a photo of one or a link to a drawing. Meanwhile, following in Macabthieles wake, I am in great admiration of the paint job on his, intact clutch cover. I must ask him how he did that super looking paint job.

Got the front brake working yesterday but I thought it still felt a little spongy. So I used the cable tie trick on the handlebar that I found on this forum, well 24 hours later it is much improved. There is a tiny amount of fluid around the bleed nipple and I have read again on this forum that it needs to be really tight. I have fitted a new nipple but I'm loathe to swing on it much more as I have given it a fair old tweak already. I'll keep an eye on it to see how it goes.

Wrap PTFE tape around the bleed nipple, it's cures the leak and prevents it seizing.

I did that with the old nipple, when I was fault finding. I thought I'd try without as it is a new nipple, however I'll have a look at doing that if it keeps weeping.
