Dear all,
I have an MKIV 1989 (AK1317).
I just realised that there is a brake liquid leakage between the airvac and the master cylinder of my Brake mastervac.
There are quite few references on the system body : ABCDEGHJKLMN 8 and 74660862 as well as a reference that looks like Q1370?
I have attached some pictures of the system.
Does anyone know what brand and reference it is ?
I would think it is a Ford part but not absolutely certain and maybe an ATE model but I cannot find these references.
Many thanks in advance for you help.
Best Regards
Laurent

I think it's a Girling part from a Ford Granada MK I 1972-1976, but I am not sure.

Noticed post on the Cobra forum regarding a master cylinder with the same markings. See:
http://www.cobraclub.com/forum/showthread.php?t=43512
Its off a Sierra Cosworth, but you need to read the whole thread. It can well be the same item as the Granada mentioned in
the previous post, but I've looked at a picture of one from a '78-'81and that has three brake pipe conections, the earlier model only
appears to have two connections. Compare pics for '72-76 and '78-'81

Here is the original Ford part number. I found a NOS master cylinder after a long search on ebay UK.

I had the same issue - got a kit from www.powertrackbrakes.co.uk and rebuilt the master cylinder. Cost £18. Works great.
