Personally at that age I'd sling it and put a new one on, lucky its lasted (if the original which it may not be) as the 300Tdi vacuum pumps are not reknowned for a long and happy life! Can't recall if the servo unit is the same on a Disco or not (I think maybe not) but the brake servo on 300Tdi Defenders is a regular failure, they crack around the bolt holes on the front of the servo can, we change loads of them at work, symptoms are a loss of brake vacuum, can be hardly noticeable except under emergency braking which is not a good time to find out... or the brakes can be as bad as if the engine was off.

Many thanks for your reply ,it is good to know you are not the only one in that situation You must be spot on ,there must be small cracks that let the oil seep when these crack widen ,i'll loose the braking power Ill be ordering a new pump tomorrow!! many thanks again and ..Happy New Year peter Quote Link to comment Share on other sites More sharing options...
BogMonster Posted December 26, 2006 Share Posted December 26, 2006 I'm talking about the servo can on the master cylinder that cracks, not the pump, but I don't mess with anything in a braking system, I change it! Quote Link to comment Share on other sites More sharing options...
