DC_ Posted August 22, 2018 Share Posted August 22, 2018 Ok so having discovered a problem with my brakes which don’t seem to be too bad. There seems to be trouble maintaining the same braking performance when going downhill and on the brakes for a good few seconds.... getting advice from another thread ( thank you), it seems vacuum is the issue. So, having replaced the non return valve on the booster, which didn’t make any difference (slightly worse if I’m honest), it’s time to get it sorted. I did the test, engine off, press pedal several times, hold pedal whilst starting engine and pedal should sink when vacuum assists....... there is NO further assist. So, should I invest in a new brake booster? Or a vacuum pump? Also did the finger test on the pump and seemed ok but, on the other thread it seems that’s not enough. 👍😎 Quote Link to comment Share on other sites More sharing options...
miketomcat Posted August 22, 2018 Share Posted August 22, 2018 Assuming your engine has the same vac pump as a 200tdi. You should have enough vacuum on the pipe to suck your finger on (imagine sucking down a straw with your finger on the end). If you have this your pump is fine so a new servo is needed.

Ex Member Posted August 22, 2018 Share Posted August 22, 2018 What engine? Suck on the booster with an see if it holds vacuum. Getting a vacuum tester (little pump and gauge) will make figuring out what is wrong a lot easier than guessing. Quote Link to comment Share on other sites More sharing options...
western Posted August 22, 2018 Share Posted August 22, 2018 2.5 n/a diesel has the same vac pump as the older TD 19J & 200Tdi engines. Quote Link to comment Share on other sites More sharing options...
DC_ Posted August 22, 2018 Author Share Posted August 22, 2018 Yes the vacuum test on finger was done and seemed ok. Thanks guys for the replies, my signature has my truck details on it but I know some can’t view it depending on device used to view the forum. Thanks again Ralph 👍 1 Quote Link to comment Share on other sites More sharing options...

western Posted August 24, 2018 Share Posted August 24, 2018 looks to be plenty of Vacuum, blanking grommet is AFU2627 Item 12 on page 478 http://www.retroanaconda.com/landrover/parts_books/110/6_vehicle_controls_brakes_fuel_air_p472-579.pdf Quote Link to comment Share on other sites More sharing options...
Ex Member Posted August 24, 2018 Share Posted August 24, 2018 Item 12 is the side plug for accessing the linkage. Quote Link to comment Share on other sites More sharing options...
DC_ Posted August 24, 2018 Author Share Posted August 24, 2018 I was thinking that too @Red90 @western on my pictures, the foam seal seems to be glued to the pedal box. After a clean up I can glue it back down.... be nice to renew it though Quote Link to comment Share on other sites More sharing options...
western Posted August 24, 2018 Share Posted August 24, 2018 Ah Sorry DC, misread the photo, thought it was the blanking grommet you wanted, try the 3 numbers below the item 18 line, they are sealing strips but not illustrated 1 Quote Link to comment Share on other sites More sharing options...
Paddy_SP Posted August 25, 2018 Share Posted August 25, 2018 I had exactly the same problem recently - when I put the brake pedal down, it continued sinking after a few seconds. When I fixed the leaking vacuum pump (due to oil coming out), the problem disappeared! Quote Link to comment Share on other sites More sharing options...
DC_ Posted August 25, 2018 Author Share Posted August 25, 2018 Thanks Paddy, there’s no oil leaking at all from the vacuum pump so I’m hoping come Monday evening, all is good 😊👍 Quote Link to comment Share on other sites More sharing options...

DC_ Posted August 27, 2018 Author Share Posted August 27, 2018 So Monday has arrived along with the new servo, got in from work and cracked on before the rain arrived. The hardest part of this job was getting the bas@#§$ing cotter pin In and out to the brake pedal. If you have an angled pair of pliers it sure does help !! what a difference in the braking performance !! I know they weren’t great but looking back at how they actually were it’s frighting. So once again thanks to everyone for their input. Handbrake also adjusted so it’s ready for MOT on Wednesday 🙏🏻 Quote Link to comment Share on other sites More sharing options...
western Posted August 27, 2018 Share Posted August 27, 2018 Good to read the new servo has made a big difference, best wishes for the truck to ace the MOT. 1 Quote Link to comment Share on other sites More sharing options...
DC_ Posted August 27, 2018 Author Share Posted August 27, 2018 Can’t beleive the difference Ralph, thanks for the best wishes for MOT..... so far all I can find is the screen wash reservoir needs topped up. 😊 1 Quote Link to comment Share on other sites More sharing options...
PolarBlair Posted January 23 Share Posted January 23 Didn't seem worth making a new post but I recently found myself with what felt like half braking power. Found this post very useful so thought I'd share my situation and ask if anyone has advice. So apparently some previous owner put in a barbed T-piece. It looked like the remnants of black adhesive which had been blocking it off had failed at some point causing the vacuum leak. I'm assuming someone had an accessory that needed a vacuum? No dangling hoses as far as I could see. It was spliced in near the vacuum pump. Temporarily put on some random hose I had lying around and blocked it off. Hey presto - working brakes! Luckily had some barbed fittings so put in a straight join with a bit of tiger seal making sure none was on the end of the barbs to avoid blocking the vacuum line. Going to give it at least 24hrs before running again. So - any ideas what this could have been for? Or have I deleted a factory T- piece that should be connected to something?

Escape Posted January 29 Share Posted January 29 That looks like a TD5. They have a vacuum take-off for the EGR valve. If the valve has been removed or forced open, the vacuum lines and solenoids can (should) be removed as well. Quote Link to comment Share on other sites More sharing options...
