adam300Tdi90 Posted July 24, 2007 Share Posted July 24, 2007 Hi Chaps, I've been trying to diagnose why I have to stomp on the brake pedal to stop! I removed the vacuum pipe from the servo and started the engine and there was no detectable vacuum coming from the pump. Therefore the pump is buggered right? Can someone who has replaced this recently tell me where they got theirs from, was it the cheapest in their opinion. What actually goes wrong with the pump and is it fixable? (I have seen an article in the tech archive speaking of this but the link no longer works) I have my MOT booked for Thursday, do you think it will pass like it is? You can stop the car and very quickly, but you really have to stomp on the pedal. My arguement would be that the brakes are fine but completly unservoed, but they let unservoed cars on the road. Will this stand up in the court of law or is it wishful thinking? Many questions I know, any opinions appreciated, Adam. Quote Link to comment Share on other sites More sharing options...
sgnas Posted July 24, 2007 Share Posted July 24, 2007 Two things it could fail on The highly subjective "excessive force required" to operate brakes the other being. foot on brake pedal, start engine, does pedal sink, no, no servo assistance, fail Quote Link to comment Share on other sites More sharing options...
western Posted July 24, 2007 Share Posted July 24, 2007 300Tdi vac pump isn't a DIY servicable part, But some have repaired theirs. if it is the pump a new one is fairly expensive. Quote Link to comment Share on other sites More sharing options...

Guest diesel_jim Posted October 2, 2007 Share Posted October 2, 2007 You're looking at about £100 for a replacement. on ebay you see a lot, i managed to pick one up for £60 (brand new) the front cover can leak on them, causing loss of vacuum assist. i think it was a south african LR site that had a thread on how to repair, which involved drilling out all the rivets for the front cover, removing it, cleaning, drilling out the rivets to accept self tapping screws, laying a bead of sealer down and refitting the front cover. But for what its worth, i'd rather spend £100 and have my brakes working in tip-top condition than trying to bodge it. Quote Link to comment Share on other sites More sharing options...

jwhitton Posted November 13, 2007 Share Posted November 13, 2007 How easy is it to repair a 200TDi vacuum pump using a standard repair kit. Looking at the repaoir kit, looks like it is just a case of remove from the engine, take the lids off and replace the vanes/blades? Anything to watch out for? Thanks, Jon Quote Link to comment Share on other sites More sharing options...
western Posted November 13, 2007 Share Posted November 13, 2007 Jon, it's easy, just unbolt the top cover & replace the 4 vanes, no need to remove it from the engine. Quote Link to comment Share on other sites More sharing options...
nicks90 Posted November 14, 2007 Share Posted November 14, 2007 when you took the pipe off the servo and checked if there was any suck - did you check at the vacuum pump or at the end of the rubber hose where it attaches to the servo? if the end of the rubber pipe - check again at the vac pump. Could be something as simple as a split pipe or internal delamination blocking it. Quote Link to comment Share on other sites More sharing options...
