2006 xj 2.7tdvi brake servo to vaccuum pipe seal/grommet
on my car this seal/grommet split causing brake pedal to go hard as no vaccuum, tried everywhere to buy but to no avail, jag dealer wanter almost 600 for new servo which has seal in it, but new part was not even similar in size, my experience at jag main dealer was to be polite dreadful and very annoying, As an engineer and worked on cars since 11yrs old i could not spend 600 on a seal or the 950 plus they wanted, after more research i was able to buy the seal, two minute fix for 20quid, hope no one else falls for it

 

You might try to seal it with RTV. Vacuum is not so strong at that junction.

 

rtv? sorry excuse my ignorance not heard of it i tried alsorts but a split rubber grommet in my experience cannot be repaired properly and should be replaced

 

RTV Silicone gasket maker, liquid rubber, etc.

 

cheers iv used similar before and it may have worked but maybe its the engineer in me feels better knowing it has a new part as opposed to temp repair if you no what i mean

 

The engineer in you might want to get familiar with WD-40 and duct tape. Keeping our old gals running sometimes requires what we used to call "field expedients".

 

For anyone else with this problem, the part that you require is JLM21101.
It's available from any Jag dealership and costs around £6.

 

Thank you so much for this I think you have just saved me £600 plus
