dlcoop Posted March 4, 2022 Share Posted March 4, 2022 Have all parts to finish the brakes. Now master cylinder has a few drops under it. I thought I had manual brakes but after looking underneath it appears to be a brake booster (vaccum line to it).. Does anyone have a rebuilt or do I just do a kit for it. These are 2 pieces and they are not together as one unit. My drips appear to come out of the boot . This only happened after I disconnected all the lines and hoses to flush them out.

old-tank Posted March 4, 2022 Share Posted March 4, 2022 The lower picture is a maual brake MC. I have no idea what that other contraption is. More pictures and a diagram of the setup may help. 1 Link to comment Share on other sites More sharing options...
60FlatTop Posted March 4, 2022 Share Posted March 4, 2022 (edited) The lines in the pictures look like copper. That is a sign someone has been there before you. Wire brush a couple of areas and check. Maybe you could get a few more pictures and Compare what you have to other's. This is on Ebay: https://www.ebay.com/itm/312727730996?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=312727730996&targetid=1263094004306&device=c&mktype=&googleloc=9005570&poi=&campaignid=14859008593&mkgroupid=130497710760&rlsatarget=pla-1263094004306&abcId=9300678&merchantid=7868454&gclid=CjwKCAiAjoeRBhAJEiwAYY3nDIOTdHvPxD9TYmS6ykNxHbgIewMTXwazGXaDnT2TZVXdxm2pwTlYvBoCTyAQAvD_BwE At one time I owned a '67 Sunbeam Alpine with a Lockheed remote located vacuum power brake booster. They are fairly common on British cars. Like the Ebay seller claims, it could be a dealer installed option. That would also help explain what looks like hand bent copper lines.

dlcoop Posted March 5, 2022 Author Share Posted March 5, 2022 So in looking more, the line that comes out of the back of the master cylinder goes into the other (contraption) I am assuming it is a booster as it also has a vacuum line going to it. Have read the service book but the description to me is very vague. Paragraph 9-15 very unclear. I think I have a booster but not the vacuum reservoir?????. Anyone have a pic of their booster system. Believe 4-56 are the same. HELP Link to comment Share on other sites More sharing options...
EmTee Posted March 5, 2022 Share Posted March 5, 2022 From what Bernie and Old Tank say above, it sounds like your brake booster is an aftermarket (or dealer installed) option. It is a different system than a factory power-brake car would have. 1 Link to comment Share on other sites More sharing options...
dlcoop Posted March 5, 2022 Author Share Posted March 5, 2022 I was on Ebay last night and found an aftermarket power brake booster. I am also convinced that it is an aftermarket or dealer installed power brake system. Which also means that I can replace the master cylinder with a manual one. 2 Link to comment Share on other sites More sharing options...
old-tank Posted March 5, 2022 Share Posted March 5, 2022 You have options in addition to replacing with a manual MC: remove the contraption, take it apart carefully to understand how it works and refurbish if possible (what I would do ); remove it and eliminate it; leave it alone and maybe at worst it would be non functional and the brakes would work as manual.

EmTee Posted March 5, 2022 Share Posted March 5, 2022 If it was added after the car was built, it stands to reason that in the worst-case scenario it can be removed. Then the car is back to "original". Link to comment Share on other sites More sharing options...
