davek Posted December 24, 2014 Share Posted December 24, 2014 Hi guys I started this topic with AGAIN because it has been discussed on this forum and others several times but I have not seen pictures to document the interchangability. I have a 73 and have had no luck finding a replacement so far. I have not contacted Black Dragon to see if the 8.5" is available. I tend to stay away from them but need too. 3 main boosters for the S30 cars and please correct me if I am wrong. 7" for 70-72 cars 8.5" for 73 to ?? 78 10.5" for ??? 76 to ??? There is another 10.5" which to my knowledge only difference is longer studs on the firewall side. Again, correct me if I'm incorrect. all 3 have the same MC side stud pattern 60 x 85mm 7" firewall side stud pattern is 70 x 80 and the other two are 70 x 100. Using the 7" booster would require drilling new holes. This does appear to a good option as it seem the holes will interfere with peddle mounting bracket on the inside of firewall. I'm not saying it's no possible. I read you can use the 10.5" and flip it over. See pictures why this won't work on my 6/73 Measuring from clutch MC to throttle bracket I get 9.25". Measuring the 10.5" booster straight across the mounting studs I get 9.5" in standard mounting position. If I would flip the booster over and measure across the studs I get over 10? Impossible to fit. Please show me picture of how others have made this fit. Flipping the booster will make for a none aligned fit to the brake peddle arm I would think. Mayb ethis is a non issue. Is it possible 73 model has clutch MC and throttle plate closer than other years? Tony said he did it in his 2+2. I need a measurement as I have shown please. FYI the 7" & 10.5" I purchased from O'reillys. 8.5" is my leaking booster. I asked for 76" booster for the 10.5" and a 71" for the 7" Please guys show me how it's done. Merry Christmas. Dave ps: I can't find spell check:) Quote Link to comment Share on other sites More sharing options...

davek Posted December 25, 2014 Author Share Posted December 25, 2014 I have not tried Napa Miles. I will Friday. Quote Link to comment Share on other sites More sharing options...
davek Posted December 25, 2014 Author Share Posted December 25, 2014 I will check tomorrow at Napa but the web parts function reads similar to all the other local and internet sources(rock auto etc etc). Searching it seems Cardone in the only remanufacturer of all vacuum brake booster no make what make or model. I'll call them soon after the holidays and see if I can find the reason for not servicing the 8.5" booster. I'd guess too small a market.

Tony D Posted December 26, 2014 Share Posted December 26, 2014 They will rebuild yours-you have to send it to them. Quote Link to comment Share on other sites More sharing options...
davek Posted December 26, 2014 Author Share Posted December 26, 2014 Napa--NOT Cardone doesn't offer a phone number. Only email to their service department. I sent an email. O'Reilly's sent Cardone a "check availablilty meassage and it came back-Part not available. I did find a place on Cardone web site that does take units sent to them and return rebuilt as Tony pointed out. However they only work thru a business customers of theirs. O'Reilly's said they will work with me. I'll continue with this topic but will be week of Jan 5th before I can send the unit to A1-Cardone. I still would like to see how others managed to FIT a 10.5" booster in there 240Z. Tony can you take a picture of your 2+2 Quote Link to comment Share on other sites More sharing options...
Miles Posted December 26, 2014 Share Posted December 26, 2014 Have you tried MSA yet? http://www.thezstore.com/page/TZS/CTGY/classic21a15 Quote Link to comment Share on other sites More sharing options...
Tony D Posted December 27, 2014 Share Posted December 27, 2014 (edited) "Tony can you take a picture of your 2+2" I'm in Lucena, Quezon Province, Republic of the Philippines 13 56' 22" N 121 37' 47" E My 2+2 is in the 951...formerly the 909...formerly the 714... 92572! 33 56' 32"N 117 13' 46" W I think Google Earth can give you an accurate ruler distance between those two points! If you can wait until middle to last week of January when I pass through, I'll snappy and post for reference. What I recall from my swap: 74 260Z 2+2, 12/74 Production Date Donor Booster was from 1979 S130 Coupe, and I used a 15/16" MC from Autozone on the buildup to replace the original MC on the donor booster. The booster was turned upside down, and the bolts were cut off to remove the distance of the big die-cast spacer that is in place on the S130's. It seemed to function well, and everything lined up straight. Edited December 27, 2014 by Tony D Quote Link to comment Share on other sites More sharing options...
davek Posted January 4, 2015 Author Share Posted January 4, 2015 My plan is to have O'Reilly's be my medium to A1-Cardone next week. I have not tried MSA. Tony, a picture with a measuring devise in the photo for reference as I have shown would be appreciated for myself & others to see. Obviously there are differences between the 2 models. Ps: I don't head back to Shanghai area until Feb. I know from other posts you live in the Philippines. I did 135 days in China/Korea in 2014. Much less time in Asia this year I expect.

Tony D Posted January 4, 2015 Share Posted January 4, 2015 (edited) I try to stay out of China, it's not worth my time and aggravation until management decides to listen and act upon suggestions of field personnel. Multiple field personnel. Technically, I'm based in LA. My company doesn't do shit for me living here in Philippines now. I just figures by saving the $26,000 in airline flights every year (153,000+ commuting miles) that something could be worked out... Instead of that, the MBAs decide to "leverage" my investment in a houseful of furniture and vehicles to "save" more money availing of the flight savings anyway since their bet is I won't pull a George Costanza and start maliciously flying back to LA for a day to get on another flight. Hey, my 500 hours a year on a plane flying over the Pacific can be spent productively....or flying. Their choice, right? New Year, new attitude. It's the year of the Sheep. "Baa Baa Motherf-ers!"

Miles Posted January 5, 2015 Share Posted January 5, 2015 When I was searching for a 78 280Z booster for my 240Z I discovered that there was a company in my hometown that rebuilds boosters and master cylinders for a variety of companies. I bought a booster from a local Nissan only wrecking yard and had the booster repair company rebuild it for $125. Check your surrounding communities for companies that rebuild boosters.

davek Posted January 16, 2015 Author Share Posted January 16, 2015 Stopped in to O'Rielly's to send my unit off to A1-Cardone today. They highly recommend not sending it. Said Cardone looses more than they ever return. Manager said he would not send his own parts to Cardone. Searching the old web I found and talked to a rebuilder in Portland Or. I felt comfortable with him and will send him my core for rebuilding. $149 plus $21 return shipping. 4-5 day turn around. Power Brake Booster Exchange. I'll post again with pictures and review when it returns. Quote Link to comment Share on other sites More sharing options...
davek Posted February 6, 2015 Author Share Posted February 6, 2015 Received my booster back today UPS.. Looks nice, fresh black paint, new rubber bellow grommet. Won't know for months how it performs but I say I'm satisfied now. I would attach a picture but I don't see the icon for it. Anyway it's shiny black and looks new. I did get a call back from Long Motor(VB(Black Dragon) They cannot measure a unit to see if it's 8 1/2" and they are out of stock with no restocking date. They know absolutely nothing about what they sell but tried to be helpful. I used them- VB --on an MG project in the past and had the same results. You probably knew this.

GIchiro Posted January 24, 2017 Share Posted January 24, 2017 What is the name of the company in Sacramento that rebuilds the boosters? Thanks, GI Quote Link to comment Share on other sites More sharing options...
Miles Posted January 24, 2017 Share Posted January 24, 2017 (edited) What is the name of the company in Sacramento that rebuilds the boosters? Thanks, GI As of 9/21/2011 Air Brake Repair Service Inc. dba Power Brake Sales 1517 McCormick St. Sacramento, Ca 95811 800-624-8185 916-446-7829 www.powerbrakes.com They had all of the parts to rebuild the booster in stock. Took less than a week. Cost to rebuild 280Z booster: $120.63 I bought the 1977 280Z booster at a wrecking yard for $50.00. Nisson Only wreckers 3561 Recycle Road Rancho Cordova, Ca 95742 916-631-8333 As I recall I used the 1977 280Z booster because the push rod matched the brake pedal clevis of the 240Z better than other year 280Z boosters. The treads of the 280Z booster push rod matched the 240Z brake pedal clevis. There is a thread in the brake section on this subject.
