+George Isted hi thanks for the comment glad the video's helped good luck with the overhaul

+greasemonkeygarage Watson. Yep, all done, went back together quite easily, but need to tidy up the bulkhead before refitting and bleeding through.

hi George bit of advice prime to servo unit before you mount it tilting it to get air out makes it easy to bleed once installed. regards Jeff

Thank you so much for taking the time and effort to upload this videos. It really helped me a lot. I have en internal leak in the servo on my MGC GT which has the same servo. I took it apart today. It still had the spotwelded clamp around the housing so it probably hasn't been touched since 1969. So I was a bit curious how it would look inside. But everything came apart without problems. Even the plug came out without problems. Took about an hour to take it to pieces. And it was about a teacup of brake fluid in the vacuum housing. Have replace all the rubbers so its ready to put back together, just waiting for the paint to dry. Again, thanks a lot :-)

Hi very glad to here the video helped, it sounds to me like you have the skills to carry out this repair just needed a picture to look at ive watched many videos that gave me the drive to get the job done. regards Jeff

Well I am an aircraft mechanic, and has been for more than 40 years, But I have never done this before. We have all fancy tools in our workshop so that helps for sure. If it was a succsess is yet to be seen, but I think so. If not, I will let you know :-)

Hello, great series of videos on rebuilding these units. I have 2 apart at the moment, a MK IIA and a MKIIB. One for my '68 Volvo 1800 S and one for my '64 Volvo 122 S. Two points: there should be a flat rubber gasket under the air filter but I didn't see you install that , and secondly it was not clear whether you painted the inside of the vacuum canister, which I would recommend not doing. The action of that piston/diaphragm sliding back and forth will probably rub the paint off and gum up the works. One of the major causes of the brakes locking up is the air piston binding up inside that canister. Some folks send the canister out for the inside to be Teflon coated to prevent bonding. The MKII A has a leather seal on the piston instead of a rubber diaphragm, and that's even more complicated and difficult to source. Also the Girling info stresses rebuilding every 40 K miles or every 3 years, so it's definitely a maintenance item. Keep up the good work!

Hi fretman6 unable to remember the rubber gasket fit its been a year now since I completed the rebuild and the car is now well covered up for winter so unable to check for sure but I do remember the seal so think I did install it. will have to check. no I didn't paint the inside for the same reasons you mention mine was remarkably rust free canister so just cleaned and dried but think this unit had been overhauled before at some time and was coated inside with some thing this had not chipped or worn so left as it was. see you mentioned the service intervals I tend to go for fluid changes every 2 years regardless of mileage would leave a full overhaul longer checking other parts ie cylinder rubber seals for general condition if there is a problem there then I would look to service the whole system. thanks for the great comment its good to hear someone else is out there doing this kind of work keeps the shared information live for all. regards Jeff.

fretman6; Yes there is a rubber gasket under the air filter. And regarding painting the inside of the vacuum housing, its not a problem on the Mk2B but it is on the Mk2A. Beeing scandinavian I have had some Volvo's in the past :-) The Mk2B is a better design, if the piston gets stuck on the A model, and at some time it will, the brakes may lock on which is normally not convenient :-)

Well done, it's absolutely amazing what you can find on youtube. I shall now try and renovate my girling servo. Was it Past Parts you got your servo repair kit from? Have you seen any Jademutley videos on his vitesse restoration project? I know a few years ago he restored a Mk11 GT6. cheers Steve

[@greasemonkeygaragewatson1069]

+Steve Hill Hi Steve how you doing made the top job yet?. yes it was past parts I got my kit from but there is another I saw on ebay your looking at £100 for the full kit there are other servo's out there for that price worth thinking about. Jeff

Hi Jeff, your video have been really helpful. I have an MGC that I have just completed the servo rebuild for. 20 years ago I bought a replacement rebuilt but with your help I chose this time the rebuild route. Fitted it today, hydraulics look ok but the brakes stay on and and stay on, the front wheels do not turn, leave it 1/2 hour and the pressure has gone. Any ideas what I may have done wrong, or what to look into, I think it something to do with the vacuum, the valves? There is no white return valve, only the red piece so I should fit an alternate return valve, even though that was not fitted previously. Thanks again Paul

[@greasemonkeygaragewatson1069]

hi Paul its difficult for me to answer this one as its clear its not venting the vac there could be several things wrong what i would try is look through the internet and try to find a breakdown of the unit manual or parts list and compare your rebuild that may show up the problems. you may well find the problem to be very minor let me no if you have no luck regards jeff
