  1. The hissing sound suggests a failed booster. After you test the booster per my previous post, and it fails the test, replace the booster. Typical booster installation errors include push rod adjustment and/or the reaction disk falling out. See the brake FAQ and brake forums for details. Suggest that you read up on push rod adjustment and the raction disk.
  2. Sounds like a booster problem. Check your booster and vacuum hoses to the booster. Also, make sure that the check valve is installed correctly. Check that the push rod between the MC and the booster is adjusted correctly. Booster check: With the engine off, place your foot on the brake pedal and apply pressure like you are trying to stop the car. Hold that pressure. While still applying pressure on the brake pedal, start the car. You should feel the brake pedal sink a bit and become softer to push. It means that the booster is working. If the pedal remains hard to push during the test then there is a booster issue. Most likely the booster is leaking or it is not getting vacuum from the engine. The other cause of a stiff pedal would be if the MC push rod is adjusted too far out such that it is pushing the piston inward in the MC. What happens is the piston gets pushed past the the point where the the fluid return port is covered so fluid gets pumped out to the brakes but can not return to the tanks when the pedal is released. So the brakes become locked. If this happens you can relieve the pressure by opening the bleeders on the MC.

    The Painless install is documented throughout HybridZ and on the web. Suggest that you purchase a copy of the Jags that Run 240Z V8 conversion manual (link below). Buy the book How to Restore Your Datsun Z Car by Wick Humble. It will save you hours of searching for "how to" info. Suggest you buy a book on auto electrical wiring such as the one pictured below.

    I had the same problem with my first 240Z. The PO butchered the wiring. Took me weeks to trace each wire he installed and put the wiring back to stock.

    What year Z? Download a schematic for your car. There are many on-line. Some are in color. Download a Factory Service Manual (FSM) For example, the 1972 starter wire is black - yellow and it attaches to the solenoid "S" terminal Don't advise doing a re-wire of the whole car at this point. From the picture: has the fuse box been replaced?
  13. Seems to be a rash of new members posting in the FAQ. They don't realize that members can not reply. Suggestion: Modify the FAQ heading to read "FAQ - is read only. Do not post here"
  14. Nice car! Welcome Useful information: Download a Factory Service Manual (FSM). http://forums.hybridz.org/topic/48825-factory-manuals-some/?page=2&tab=comments#comment-1208329 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.
