XJS - 1988 V12 convertible Teves III (with square reservoir on top of the master cylinder)

Hi. We have had the same problem with the car unexpectedly veering off to the right when braking. We’ve removed the pedal assembly and removed / drained & sent the valve block away for service/repair.... it has now been returned with no fault found. All valves operating. We need the 3 ‘O’ rings that seal the valve block to the master cylinder as the old ones are hard and out of shape. Can anyone help...? Thanks

 

Orings can be sourced from suppliers if you match sizes or get lucky with a Jag supplier that did the work for you.

alternatively OrangeBlossom having been thru hell with the brakes says likely its the electrical strip not an actual physical fluid or oring failure...I have same issue on 89 XJS, I'm sure he'll post here if he sees a brake thread lol...

 

Another 89 XJS here.... with same problem....
