  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"

  15. The reason I eliminated the tank was to eliminate gas odor inside the car.
  16. On my carbed SBC I removed the vapor tank and sealed all of the ports on the tank except the fuel pick tube and one port on the top of the "bulge" part of the tank. I ran that one vent line to the neck of the filler tube so air could escape as the tank was filling up into the "bulge" part of the tank. If the tank is completely sealed, a vacuum will develop as fuel is drawn out of the tank. To prevent the vacuum, I drilled a very small hole in the filler cap. Other consideration: with the vapor tank removed, do not top off the tank when filling up. On hot days the gas will expand and run out of the cap. Done this for 20 years with no problems.
  17. Most likely a bad ground in the brake light harness at the back of the car. Pull out the rear panel and look for the ground wires and clean up their attachment points. Also could be a dirty lamp socket. Pull the bulb and check the socket. Suggest that you down load a schematic for your car. You are going to need it as a Z owner. Ditto a Factory Service Manual (FSM).
  18. This is interesting. I pulled the R200 and half shafts from a 78 280Z, replaced the U joints and installed the R200 and half shafts in my 240Z. Are you perhaps thinking of the driveshaft? Take the half shafts to a drive line shop.
  19. The strap is no longer required. The stock rubber differential mount you replaced would flex and rip apart eventually. Nissan installed the strap to keep the nose of the differential from pitching up under load. For normal daily driving the solid mount works well. But the racers have reported that under hard driving the front cross member can crack and/or pull the center bolt through the cross member. I installed solid mounts in both of my Z cars 20 years ago and have not had a problem. Cars present us with lessons. The lesson is repeated until we get it and then we get another lesson etc etc.
  20. Just to be certain. These are the bolts you are working on:

  22. That solid mount you are installing may require longer bolts anyway.
  23. Why not just remove the differential from the car and apply heat to the nuts?
