mbm Posted August 25, 2015 Share Posted August 25, 2015 Hi all,I´m helping a friend to get on the road a 200 Tdi that was parked for 4or 5 years.The clutch pedal had any pressure so we replaced seals on master and slave pumps, bleeded and still no pressure.The master pump has pressure, the slave has pressure (tested manually and out the LR), tried reverse bleeding and still no pressure.What are we doing wrong?(Seals are in the correct position...)

Les Henson Posted August 26, 2015 Share Posted August 26, 2015 Clutch fork hasn't punched through on the pivot point has it? Did the operating rod stay in place when you removed the slave? Les. Quote Link to comment Share on other sites More sharing options...
mbm Posted August 27, 2015 Author Share Posted August 27, 2015 Thanks, Les: Clutch fork was checked and the operating rod is in place.... Quote Link to comment Share on other sites More sharing options...
robertspark Posted August 27, 2015 Share Posted August 27, 2015 master seals in the right way around ?? some of them have a cup washer (to be fair you should get some resistance the wrong way around though...) if you remove the hydraulic line at the slave cylinder end... stick your finger over the end of it and someone pumps the other end... do you get pressure?? If so... problems in the slave.... if not .... problem in the master .... ... note .... I haven't done one for a while so I may be taking out of my rear ... but worth a think and check?

mbm Posted August 27, 2015 Author Share Posted August 27, 2015 Rob: all seals and washers are in the right place, slave too. I can feel the pressure in the master.Les: how can I check the operating rod issue?I have removed the slave and the operating rod, mounting I have felt a big pressure to place the pumpand suddently it went to his place (other way wasn't possible to do the bolts...) I´ll check again. Quote Link to comment Share on other sites More sharing options...
Boydie Posted September 1, 2015 Share Posted September 1, 2015 Try disconnecting the hydraulic line to the slave cylinder at the slave cylinder, and to ensure that you have fluid flow - push back the "nut" and put a hose over the tube and put the other end into a 1/2 filled clear bottle of brake fluid , once that full flow has been established, and any air has been exhausted reconnect and bleed the slave cylinder. If you don't have a good flow, the problem is at the master cylinder, if you do and the slave cylinder still isn't working the problem is in the slave cylinder. If both are working then the problem is at the clutch lever/push-rod. Quote Link to comment Share on other sites More sharing options...
