Clutch master to slave pipe

[Sloppy 2000]

Hello. My master to slave pipe of the clutch needs replacing. I have a Mk 1 with the raised reservoir that is connected by short tube, so as to avoid the Servo. All that is ok. Its just that the master to slave pipe is leaking. It could do with reflaring at the master end. it must have been undone and redone up many times in its life. It is a 68 so has had 54 years of grubby hands. There are kits out there to do it in situ, but they are 3/16th. I don't think this would be the right size (what is?). Is there a full hose that I can buy for this single circuit master. CW has a mark 2 flexible pipe but noting else. There appears to be one on rimmers.

I am not sure it is for MK1 or mark 2.

I did (until this leak) have the trouble bleeding the slave. I turned it up the other way and that has helped. If anyone has used the one in the link. Can you let me know if it allows you to rotate it, so I can get all the air out.
So 4 questions:

1 What tool and size should I use to flare the pipe?What is the size of the pipe. (non flexible)
2 Has anyone used the one in the link above. If so, how did that go
3 Does the pipe in the link give the benefit of being able to rotate the slave 180 degrees so that you can have the bleed nipple at the top to get the air out.
4 Before replacing the slave, the bleed nipple was at the bottom. Should it be, when fitted, with bleed nipple at the top or bottom?

Thanks in anticipation.

Mine has the bleed nipple on top. Bleeding involves nothing more than opening the nipple half a turn and letting a bit of fluid out, bubbles first.

I notice that there are two slightly different styles. Mine has the two ports set at a slight angle, but the illustration in Autobooks has them both parallel and horizontal. I don't see anything that prevents the cylinder being mounted either way up - in fact I've read somewhere that the two ports are identical so pipe and nipple can be fitted either way round - but obviously nipple on top makes bleeding easier.

Hi Jeff
In no particular order, firstly the slave cylinder should always have the nipple at the top to allow the rising air bubbles to be bled out. The clutch pipe on rimmers site is a Mk2 flexible item.m I am sure that the threads are the same in the master and slave cylinders between Mk1 and Mk2. CW also shows the Mk2 pipework. Maybe that is the way to go.

Hi Jeff,
If you aren't fussy about originality, the red flexible pipe will work ok on your Mk1.
However, to keep it looking as original, I've seen members Mk1's with the clutch pipe made from copper. Copper can be easily shaped to route it with the relevant unions which should be readily available. The slave end of the pipe needs to be flexible to allow for engine movement - either with a couple of loose circular winds, or better still a section of rubber pipe (compatible with brake fluid) between the copper and the small metal pipe from the slave.
The red Mk2 hose would be easier - you could always sleeve it so that the red colour doesn't jump out as much!

Thanks John. Do u know where they do red ones. The one Rimmer's is white.

Hello Jeff,

as I have had problems in the past with the flexible hose, when it gets warm it expands and the clutch can be reluctant to give clean engagement of the gear.

I make up the line in 1/4"copper and use a short flexible hose at the slave end. The fittings are UNF, but I forget the size, possibly 7/16", the pipe and the suitable fittings are readily available?

Hi Jeff,
I would be tempted to go for the white version from Rimmers - it won't stand out as much as the red one!
Chris Witor also does a couple of versions - a plastic pipe and also a braided version. He also does the original style short flexible link pipe at the slave end as the original on a Mk1 if you chose to go down the route of original metal pipe.

I did the same as Alec a few years ago and have had no
t rouble since After a while the colour blends in with the surrounds !
