what years and models will work for a conversion to a vacuum brake system?
David …
1987 to 1989 for sure.
From 1990 to 1994 Jaguar changed to the Teves Hydro boost system which used a different type of master brake cylinder so I’m not sure about those years.

David any year that had girling brakes with the hydraulic boost and the engine driven pump.Google "Jaguar specialist " the kit maker they may have one for other years as well. John
In 1990, Jaguar changed the brake boost system. The engine-driven pump was eliminated and the Teves system was installed. This system uses a motor-driven pump on the firewall to provide the mineral oil pressure to boost the brakes. This Teves system also differs in that it does not use a traditional master cylinder but rather has an “actuation assembly.”
Has anyone out there done a vacuum brake conversion on a 1990 - 1994 XJ40 ?
well time to bite the bullet, wife needed the car and when I put it in the drive there was a big puddle of green expensive brake blood on the ground! No more hemming and hawing I bought the kit.
