These seem to be a great idea, Larry, even easier than the Eezibleed system. But they don't list Jaguar in their imported makes section. Do you know if ones that fit another car would suit 40s and 300s?

Aidan, I think you just have to match up the thread pitch and possibly length to get the right ones, a lot of these sold on ebay quote the sizes, so not too difficult to match up - one time I had a bad bleeder and I ended up picking up a Mercedes bleed valve, same thread but a little bit longer ...still worked though.
Check out the listings on eBay

Thanks for the link, Larry. I suspect these will come in handy one day.

OK now I am miffed, changed masyercylinder for known good one, bought vacuum bleeder, bled rear brakes using the cars pump as per the advice on the forum. Bled front brakes but never got anything but bubbles with ignition on and off so got a visibleed which is a one way valve on a tube and you clamp it to the nipple. Front brakes bled in 10 minutes. Have I got a pedal????????
No the pedal still goes to the floor, abs light went off briefly when I took it down the road but stays on now. Feels like the master cylinder still as the brakes do work if you stamp on the pedal. I cannot spot any leaks but cannot rule anything out due to the place I am having to work. I am not having much luck with the weather either (it's raining again) so I am trying to hit things in short bursts. Any advice?
Are you able to bleed the mastercylinder/boost pump if so how?

Sorry, but your problem now seems to be beyond my ability to advise you. When you say you bought a "vacuum bleeder" what product is that?
I hope someone else on the forum with more knowledge and experience can assist you. Good luck and please advise us of the solution.

Thanks for your post Aidan,
The vacuum bleeding tool I bought is identical to ebay number
223949712886
The idea is you hook it up to the bleed nipple create the vacuum and undo the nipple to let the vacuum drag fluid down the lines. In theory it should work but I think the plastic tube had problems sealing and I just got bubbles.
I will keep you informed of my trials and tribulations.... :roll:

Update,
Well it seems that I mis diagnosed my brake problem. There was no evidence at all of any leaks but the reservoir level did get lower. It seems that dot4 soaks into a packed fine gravel road very quickly and is invisible when it is wet. With the recent good weather the road dried out and there was a huge fluid stain under the n/s front wheel. Asked a passer by (before the lock down) to press the brake pedal and flexi hose failure was obvious. Ordered, delivered and fitted now and I have brakes again, thank heavens. For your information I bled the brakes in next to no time with a tool purchased from Halfords for less than £10, called a visi-bleed it is a one way valve on a tube that you clamp to the bleed nipple, it works really well and I didn't have the ignition on either.
Thanks to all of you who offered help, it is appreciated. Stay safe all of you.

Well that's a great result! Glad it all worked out for you despite the worries en route.
