  1. I was going to suggest you contact Randy, but I no longer have his contact info. He used to advertise on Sacramento Craigslist.
  2. Welcome You may find this information useful: · Download a Factory Service Manual (FSM). http://www.xenonzcar.com/s30/reference.html · Download electrical schematics for your car. PDFs are easier to read than those found in books. Some are in color. · Buy the book How to Restore Your Datsun Z Car by Wick Humble. It will save you hours of searching for "how to" info. · Focus on searching Hybridz as 99% of questions have already been addressed. · Start bookmarking Z car parts suppliers - there are many! · For SU carbs, parts and instructions go to Ztherapy. Buy the "Just SUs" video. · Remember these are 40 year old cars and will need restoration to be safe and drivable. · Join ClassicZCars.com website and search there as well. · Become well informed about modifications before asking questions. People will be more inclined to answer informed questions. · Search the Hybridz forums. · Read all of the new member guidelines and FAQs Links: https://www.datsun-240z-upgrades.net/ Recommend the headlight relay harness http://zhome.com/ https://www.zcar.com/ https://www.classiczcars.com/ http://www.zcarparts.com/ http://www.arizonazcar.com/ http://www.jagsthatrun.com/index.html http://www.ztherapy.com/ http://www.xenonzcar.com/reference.html
  3. In your part search contact Eric Neyerlin at https://zparts.com/ 541-670-7310 Eric has been collecting and selling Z parts for over 20 years

  5. The part number you gave is for a relay inhibitor switch. You sure it is part of the light circuit? https://www.nissanpartsdeal.com/parts/nissan-relay-inhib-sw~b5230-89985.html The right half of your schematic is missing. Here is the complete schematic which shows the combination switch (lights, wiper, washer and turn signal). The combination switch is located on the steering column:
  6. Contacts in the TS switch need to be cleaned and/or adjusted . Common problem for all Z cars. You can repair the TS switch. Search for turn signal repair. Start here: https://fiddlingwithzcars.wordpress.com/2012/12/04/turn-signal-repair/
  7. You measure from the face of the aluminum spacer on the booster to the tip of the push rod. So, if you replaced the stock 7/8 MC with a 15/16 MC, which has a deeper socket, you adjust the push rod out 0.53"as measured from from the face of the aluminum spacer. The 0.53" is a starting point. You may have to fine tune the push rod length by making small changes and then road test the car to make sure the rod is as close as possible to the bottom of the MC socket without pushing the piston too far inward which will cause the brakes to drag or lockup. If the push rod is adjusted too long, the piston will block the return port in the MC and the brakes lock up after 2 or 3 stops. If this happens, open the MC bleeders to relieve the built up fluid pressure, limp home, and adjust the push rod a little shorter etc etc. If the pedal moves too much before engaging the MC you will need to lengthen the push rod in small increments. Note that you do not have to remove the MC to perform this adjustment. Just remove the mounting nuts and then pull the MC out and push it aside. There is also a tool to measure push rod length.
  8. Look here: http://www.classicperform.com/TechBook/BrakeTroubleshoot.htm
  9. Please post a picture of your front calipers.
  10. Again I ask, what size MC did you install? Calipers require a larger volume of fluid. So the pedal goes low because the MC has to pump more fluid. You may have to install a 15/16 or 1 in. MC
  11. one more thing to check. There is a push rod between the booster and the MC piston. The rod is adjustable. When you change MCs you have to adjust the push rod because the piston socket depth is different between the 7/8 MC and the 15/16 MC. Look it up. If the push rod is adjusted too long the brakes will lock up because the longer push rod prevents the piston from retracting all the way which blocks the fluid return port inside the MC. This will result in your brakes locking up after a few stops. If this happens while road testing just open the MC bleed screws and limp home and readjust the push rod. If the push rod is too short you will experience a long pedal because the piston is not pushed far enough to fully engage the brakes. That is, the piston is not pushing enough fluid. Your brakes will feel mushy and you will experience a pedal with long travel before engaging the piston Do a search for push rod adjustment. It is critical to properly functioning brakes and brake feel.
  12. Do your speed bleeders work with your Motive power bleeder ?
  13. Yep, p/n 639560 for the front calipers https://www.ebay.com/itm/Russell-Brake-Caliper-Speed-Bleeders-Front-Rear-for-1970-1973-Datsun-240Z-/192230009783
