Hi all my 05 TD6 has developed a brake fault! after 3 to 4 seconds applying the brake it goes hard (we know the jokes lol) when i run the engine (with bonnet up) then switch off and listen to the area where the servo is i can hear a hissing. new servo i think? just wondered if you guys have replaced one and how long it took.

Still love it!!!!!! If i could would you!!!!

Diseasels don't have a servo it will be your vacuum pump . 2008 MY Supercharged

Yes they have servos, they also have vacuum pumps.
Worth checking the vacuum hose adjacent to the servo, you might be lucky it could just be leaking somewhere. possibly the connection to the servo.

thanks will have a look tomorrow If i could would you!!!!

Right I first took pipe off the vacuum pump to make sure that works and all fine, I then checked all pipe work again good. Then I got the wife to sit in the car with it running and for her to switch off the engine and then press the brake, a big woooosh sound and then no brakes. Ordered new servo and removed old one ready for it arriving, such an easy job if any one needs any info then just drop me an email.

Have a little look around the forum using search. I remember something similar being reported on here (TD6 engine) and that it was considered "normal". MY 2010 5.0 SC Galway green and sand interior!!
Have the Faultmate MSV2 Extreme to be tinkering with the settings etc. !!
