mk2 and mk3

[fortyeight]

hi can anybody tell me if a mk2 and a mk3 master cylinder are the same cheers

[AlanN]

This is my MK3 AP master cylinder, anything like a MK2?

[Muttley]

Yes it is, but it aint that simple There are so many variations in bore size and pipe sizes that you really need the number off the little tag that hopefully is still attached

[fortyeight]

mine look like that, im asking in case i need to replace them, as im having ishews with the brakes and wondered if they would fit the mk2 servo master cylinder stait swap as i cant get hold of the mk2 ones without buying new silly money,cheers

[FredTransit]

it won't fit mate, but the whole servo/master from a mk3 will. I think bungle found the LDV fits but don't know which model (presumably the convoy). Either way you are looking at new brake pipes unless you go for like for like

[Altransit]

My 1988 Sierra one looks similar, if that's any help

[Muttley]

They all look similar, differences are the distance between the mounting holes and position of brake pipe outlets and bore diameter. I found there were 5 different types of m/cyl fitted to my 1987 MK3 and 3 types on my 1982 MK2, they all looked the same though

hi can u put some more pictures on showing above where the pipes go on the servo and the pipes coming out of the master cylinder to the cylinder above the servo because looking at this it looks like mine as this type on cheers

[fortyeight]

hi taking a closer look it is different to the mk2 ,on the mk2 the resovoir is srewed on with 2 screws

[AlanN]

Some Mk3 ones are the screw down type too

It seems cylinder wont fit on servo?
because of mounting points or shaft length or else?

(just had mine painted, actually master cyl also repaired, but now wont bleed through and has strange step when pressing pedal in middle.)

anyway i got a replacment master silander and servo but not needed as i think the problem as been solved
