I am looking for a new/reconditioned Jaguar Mk 2 brake servo. These are pricey from Jaguar specialists, but I suspect that the same servo is fitted to other vehicles (eg Land Rovers), and would be much cheaper. Can anyone advise? Thanks, Ian.

If you are not really stuck on originality, I suggest look at other brake boosters.
The PBR VH40 is a great replacement. In Australia they run from A$200 to A$600.
It is typically only the fraction of the price quoted for an original booster rebuild.
If you sniff around, you may be able to dig up a similar replacement in the European area.

i purchased one recently, they can be had for 300 to 500 U.S. at the usual parts outlets for jags, although it's not really a jaguar OEM part.. it's probably a reproduction. a used one, if it can be found, would be about half of that. i think i bought mine here...

Thank you for the above pointers. The SNG Barratt offering is still over £200, whereas typical Land Rover ones are around £60 and look remarkably similar.

I think the boost ratio of the original servo was 3:1. The alternative offered by SNG and others is more like 4:1. A lot of the less expensive remote servos have a boost ratio around 2:1. Since the standard Mk2 brakes, though they work well, require a strong push, a 2:1 servo might not be very comfortable to use.

Disc brakes require higher pressure than drum brakes
I suspect the Land Rover booster would be for drum brakes and not suitable for disc brakes.
MK1 3.4 s with drum brakes used the same booster as the disc braked cars including MK2s however they were fitted with a restriction valve/port to slow the onset of otherwise harsh braking.
