411 master cylinder
Kevin I have researched this closely.If you check photos of various cars you will find series 3 4 & 5 all have a plastic tank , These are common to 70s80s range rover and are held in place with 2 studs on the firewall. What has surprised me is that series 1 have the same mounting system although a completely different cylinder. As you can see from the photo mine doesn't mount that way rather it has 2 cross bolts which attach to two parallel fabricated little walls .These are clearly original on my car. A search of the internet found a site CLASSIC PARTS on ebay. They list my cylinder as suitable for 411 1969 to from memory 1977.Listed at 365 pounds.
My brother Geoff had a series 1 which has chambers of different sizes. He purchased a kit from Bristol Cars but being very old stock it failed. With some modification he eventually fitted an xj6 mk 1 cylinder.
Clearly then there are at least 3 variations that i know of.
Im hoping to find a brake specialist in Melbourne who carries a large range of separate rubbers. Any clues ?
