Worth speaking to Tony Wood first and taking advice from people here who have had servos rebuilt, but it looks as though those that use s/steel cylinders may be the best. I seem to recall that NOS are often not so good. Regards David Brake people said $800 plus, they were under the impression it was a Mk. II and not a IIB, which I think was my fault via a txt message error to my father in law. Looks like I'll be getting one from the UK after all lol -Andrew |

Whatever I do I'll be getting it resleeved for sure. I'll give Tony an e-mail and see what he reckons. The chap at bmccomps.co.uk/products.php reckons he could do it, but I need to look into the cost of shipping as it could cost quite a bit. What I'm thinking is do the rebuild myself and get a local shop to resleeve it. Am I wrong in assuming that it's just a replacement of the seals and clamp? Nothing else that needs to be machined? The full repair kit is 100GBP from what I can tell  -Andrew |

Repair kit seems to be anywhere between £100 and £140, Indy. It's the going rate. My personal opinion is that it's an absolute rip-off, but what can you do? It's old, the parts are rare and you can't get the two piston seals and the big clamp band (Which are the bits you really need) on their own.
I'm afraid you'll have to take the hit............
Quite fun stripping it and re-building it yourself though.
Chris.

That's the fella. Bear in mind I had to jig things round a bit, as I had to mount the tank end on the bulkhead.
3:1 ratio as well.

Yep, I'll be sure to mention it to Tony, he says he has a good supplier for the servos _b

Andrew If you do go for the repair kit check out that rubber right angled pipe in the photo carefully. I had two of these fail. The first developed a slight split that I sealed and my neighbour who worked for Girling thought he could replace it and pulled it off not realising that it is held in place by a feeble insert inside the servo! Fortunately he was able to get an overhaul kit and it wasn't too difficult to repair. The second one on another car failed when I took the car to a local garage to pump up the suspension and somehow they managed to catch the pipe and it pulled out of the body. They stuck it back in place with superglue without telling me but that didn't last too long. If I ever have to take one apart again I would definitely look at improving this connector so it could be replaced without dismantling the servo - maybe I have been unlucky but at these prices.... Regards David PS There is now only one left of the one your posted a link to on Ebay Whatever I do I'll be getting it resleeved for sure. I'll give Tony an e-mail and see what he reckons.

The one that used to be on the car had a split elbow. I fitted a grommet into the hole and used a short piece of brass tube which was a tight fit into it. Lasted about 5 years before the servo started leaking.

Now that would have been a lot easier! Good tip. Regards David The one that used to be on the car had a split elbow. I fitted a grommet into the hole and used a short piece of brass tube which was a tight fit into it. Lasted about 5 years before the servo started leaking. Chris. |

Chris Is the one you are using a genuine Lockheed servo? I imagine from the lowish prices quoted on Ebay that the Lockheed type are copies of unknown quality? Anyone have experience of them? David |

The one I bought was Delphi new-old-stock (Delphi/Lockheed - same firm). The current ones are branded Powertune and are Chinese.

Well here's hoping Tony's supply is decent NOS. Don't mind paying a bit more for that piece of mind.

It's rather unfortunate what has happened with Chinese manufacture.
How it works is thus:
Indy Engineering (PTY) wants to manufacture 200,000 left handed flugelhorn widgets. The Chinese will build a factory for you to do it in, but whilst its your manufacturing facility and will manufacture precisely to your specification, it remains the property of the PRC. Six months later, when somebody else wants the same product at a far reduced price (Because someone sees a market for further left handed flugelhorn widgets), the same factory ('Cos it's not yours) will do it, to the reduced specification (and, more importantly, cost) and make cr*p. It's not their fault, they make exactly what the customer wants.
This manifests itself in the UK in my business with domestic appliances. I am now at the stage where it's easier and better for my business to refuse to service these machines. I can make them work, but I can't make them better.
I would suggest that the servos are a reasonable bet. They've only been available this year as far as I can tell, so we haven't hit the second stage (ie - cheaper.......) yet. I worry about where they'll be in two years time.

Interesting analysis Chris. I also do wonder about companies that recondition the servos. Where do they source the diaphragm and seals? Are they NOS in which case have they deteriorated or are they being manufactured to a high quality.
These are life critical components especially on single circuit braking systems. Has anyone explored options for fitting a currently manufactured combined brake m/s and servo? These will all be dual circuit but could be connected to the front and rear brakes with a suitable pressure reducing valve in the rear brake line I assume. Not an easy conversion but longer term may be the only safe solution?
