Hi this is Jim long time since i wrote on here just pulled tarpaulin off front of car today lifted bonnet,the lockheed master cylinder and servo looks like it requires a overhaul or new one.Can fit a repair kit in master cylinder on ebay for £15 inc postage SSB905 but can't find any servo's anywhere does any one know if there's any other servo's from any other vehicle can be fitted.Its a 1973 Vauxhall Viva HC 1256 auto with lockheed Master Cylinder and front disc brakes reg no SXE 579L thanks for looking.By the way on my previous posts i got the registration no wrong thaks again Jim.

Are you sure you need a replacement servo or are you just trying to replace items cos they have been stood a long time?

As Fred says, the servo will probably be serviceable but not look great. Best to try it and see.

Triumph TR7 4 speed servos are very similar and would probably fit the bill OK. The vacuum pipe location may be on the opposite side of the master cylinder, I'm not sure. Just check that the overall diameter is the same and the cylinder mounting bolts are horizontal like the Viva.

Thanks for you're replies the car not in running order yet the servo in all honesty just looks a mess would probably clean up and re-paint will post some pictures of the car tomorrow hopefully.Will buy a repair kit for the master cylinder make my own brake pipes up anyway the engine bay doesn't look too bad just need to have a really good look underneath the car and check the state i know it needs some welding looking forward to getting started.Thanks again for you're thoughts.

Be careful with the brake pipes. The majority of the fittings are UNF but there are some master cylinders from about 1973 that have M10 fittings. If the master cylinder is M10 the rest of the car will still be UNF. Unfortunately UNF male fittings can be screwed into the M10 female at the master cylinder but will be difficult and never seal properly. My advice is to try M10 and UNF male fittings into the master cylinder before making the pipes to see which fit best.

The best way. If you try both fittings, the loose one will be obviously very loose compared to the other. Metric fine, I think.

there are always Chancers on ebay trying it on with greedy prices - we have bottom ball joints in Club Stock at reasonable price - good contact though you have identified there - perhaps you can put it in Suppliers links at the end of For sale and Wanted please.
