Hello,

I'm a new owner of a 1972 corniche, but i have a rear hydraulic leak in left side , i take some picture i think it's this horse... I need some advise to change it. Do you have a parts number and how to make bleeding ? Thanks.

That is a high pressure height control valve hose. The herringbone pattern on it and the other hose in the picture indicate that it is a very old hose. ALL hoses with that pattern should be replaced now as they are well past their end of life. Your closest parts supplier is probably Flying Spares in the UK. Look up the description and order by that on their web page. Bleeding procedure has been posted many times in the past here, just do a search on this forum for "Silver Shadow brake bleeding" and lots of posts will come up.

Hi Erwann,

It looks like you are in France, you can ask Marc SAUZEAU all aprts you may need as he is The french specialist:
The best is to send him a request through his website.
Advantage is that he has high quality parts and being in France you will not have to pay the ne Brexit taxes...

I would think that you will need a full set of hoses and a complete flush and bleed of the whole hydraulic system. Maintenance on that car has been neglected and it is probably dangerous to drive.

And every hose, including the one pictured, is nothing special as far as brake hoses go. The only special ones are the ones from the accumulator valve bodies out to the actual pipework on the car itself. See the chart I created in the:

RR & Bentley Parts, Repair, Restoration & Other Resources Compilation

You definitely need new hoses though as if that's currently the only one "weeping through" it certainly won't be the last if they're all of that vintage. And it is a big safety issue, as @shadow 11 has already mentioned.

Thanks Brian,

Just a little mistake in the email which is : [email protected]
VIN is absolutely necessary in your request
It might be easier to contact him also through the website formular
