    And to all those who wanted to pontificate on whether i should or should not be working on my car remember your opinion doesnt count if its not on the subject. To all those who kept on topic i value your opinion.

    Yep i did. It was the check valve. After replacing brake fluid got better brakes than it had from new i think. Maybe the 550 booster helped that. Thanks for your input.

    Yep thats all well and good. BUT the manual shows a check valve for the Petrol engine. It does not show for the diesel hence i dont think it has a check valve.

    Somthing more to think about. I have done all the brake work on this car since i bought new in 07. When bleeding the brakes yesterday i had to have the engine running to get any fluid out. Now i dont remember having to do this before.

    I did test (a) above and its fine. I then went looking for Lack of Vacuum even though the finger over end of hose showed it was good. I made a T and put in vac line to booster. The vac gauge shows 28 in/hg which is perfect by the manual. Not bad for a 290k vac pump. Repeated operations of the...

    Discount the pedal going to floor. Had a leak. Just took it for a drive. You get one application of the brakes and then goes hard. Same as before. I think losing vacuum. Will check all the pipes.

    There is not a lot on the forum regarding Brake Boosters as i suppose they rarely play up. The symptons i have are i apply the brakes and work ok. I might get a second pump but after that the pedal goes hard and and l am looking for an exit strategy with both feet on the pedal. Cars done 290k...
