Richard Oben Posted April 4, 2018 Share Posted April 4, 2018 Get your favorite bottle of whatever relaxes you. Lay down close your eyes think of nothing, empty you thoughts as much as possible. Then in the first sliver of conscientiousness what color is your dream car? Don't over think it. JMHO. PS we have this problem with lots of guys and the FFR color choice. LOL.

trackzpeed Posted April 10, 2018 Author Share Posted April 10, 2018 Ok, after all the years of owning Z's, this one in new to me..... I have an occasional very hard break pedal that I have to really push on to slow my car down. With my foot on the pedal and revving on the engine the pedal rises a bit....... Do you think my booster is going bad or the vacuum check valve? I have a race on the 15th so I'd like to get this resolved... Thanks Jim Quote Link to comment Share on other sites More sharing options...
G-Tech Posted April 10, 2018 Share Posted April 10, 2018 Assuming your master cyl is an upgraded one based on all the other mods you have. You probably are confident that's not the problem...I'd say start with the check valve (easier fix) then there isn't many other options than the booster....when my booster went, it was after sitting all winter and the first time I got in it the pedal just fell to the floor and I ended up with brake fluid In the booster ...good lock, let us know what you find.hope this helps, I didn't see anyone else chiming in so figured I'd give you some kind of input Quote Link to comment Share on other sites More sharing options...
Richard Oben Posted April 11, 2018 Share Posted April 11, 2018 Booster had the same problem. R Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted April 11, 2018 Author Share Posted April 11, 2018 Thanks guys. Yes the master has already been upgraded when I went willwoods. I believe it's the booster at this point..... any recommendations on the best replacement options? Quote Link to comment Share on other sites More sharing options...

Richard Oben Posted April 11, 2018 Share Posted April 11, 2018 If stock worked for this long go back stock. I have the WW MC and have the stock booster. Make sure the plunger measures the same on the MC side. Don't ask how I know.... Richard. Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted April 13, 2018 Author Share Posted April 13, 2018 New booster arrived today. Hope to have it in and race ready for Sunday. Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted April 15, 2018 Author Share Posted April 15, 2018 Went to pick up the booster that “arrived” and it turns out it didn’t. Won’t be here until Tuesday. It rained here anyway so the race would have been a bust.... next race in May. Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted April 21, 2018 Author Share Posted April 21, 2018 Still no parts. Kinda sucks to be promised parts that never materialize. Trying (unsuccessfully) to be patient. Lol 😂 Quote Link to comment Share on other sites More sharing options...
JoeK Posted April 23, 2018 Share Posted April 23, 2018 I ordered a rebuilt booster from Rockauto also, showed up 2 days later. Might cancel from your original seller, if they can't produce the darn thing. Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted April 24, 2018 Author Share Posted April 24, 2018 Finally showed up today. Hope to have it in before the weekend. Quote Link to comment Share on other sites More sharing options...
Suchfun240z Posted April 27, 2018 Share Posted April 27, 2018 (edited) Hey Jim, I think the gray would look really great... another blue color you may like is a 2002 year bmw color Laguna Seca blue. It may be worth taking a look at? I painted my motorcycle this blue. Your build has given me so much inspiration for my build!

trackzpeed Posted April 27, 2018 Author Share Posted April 27, 2018 sweet bike! Love love love your bike build. Nice work. Thanks, Jim Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted April 29, 2018 Author Share Posted April 29, 2018 (edited) Well the new booster is in..... can’t believe how well the old girl stops now. I believe the old booster has been failing slowly for awhile and I just grew accustom to weaker brakes over time. The only modification i had to make was to drill and tap the clevis. The new booster had the 10x1.25 push rod and the old was and 8. I can’t tell you what a braking difference the new booster has made. My wilwoods have come alive, but my back is damn old to get under that dash to many times. Lol 😂 .

trackzpeed Posted April 30, 2018 Author Share Posted April 30, 2018 Stock replacement booster. Trying not to “fix” what already worked. Can’t wait to hit the track. Quote Link to comment Share on other sites More sharing options...
Richard Oben Posted April 30, 2018 Share Posted April 30, 2018 Yup, went from no brakes to great brakes, new booster was magic. Keep it simple keep it easy. Richard. Quote Link to comment Share on other sites More sharing options...

trackzpeed Posted May 1, 2018 Author Share Posted May 1, 2018 Parts suppliers don’t necessarily understand the difference between early and late model 240Z’s. The late model had larger diameter push rod than earlier. Easy fix all in all. Like most parts for 45+ year old cars.... they need to be modified a bit to work.
