On the 240Z the dash light is turned on by a differential pressure switch mounted on the fender below the master cylinder. The switch has a shuttle valve that moves to the low pressure side of the switch if there is a leak in the front or rear brake circuits. When the shuttle moves, it grounds the wire attached to it and turns on the red brake light on the dash. The shuttle also stops fluid from flowing in the low pressure side of the switch. So it tells you that there is a leak/failure in the brake system which most people would notice without the light.. After 40 years the shuttle is most likely corroded and stuck. The red light is also turned on by the parking brake. The 280ZX master cylinder has a float switch that is triggered when the fluid level drops for some reason. That is it. Why bother with it?

http://www.ztherapy.com/ buy the video "Just SUs" You will be able to diagnose and repair any SU carb. Well worth the money for anyone new to SU carbs.

Check that your battery is good and that you may have pulled some wires loose. Also, check that the alternator is ok. Autozone etc can check the battery and alternator.

Hmmm. One bowel has fuel and the other bowel doesn't. I believe you have the answer.

Note: most of the popular disk upgrades do not improve braking performance. They actually reduce stopping performance and result in an unbalanced braking system. Many people regret doing the rear "disk upgrade" once they realize that it doesn't perform well and then they have to change other brake system components (domino effect) to make it work. Check out the brake balance calculations associated with various disk brake "upgrades" posted in the brake section. Hybridz has the most reliable information about Z modifications, but you have to dig it out.

What car and engine would help?

Autometer is the old standard for Z cars, but there are many new gauge brands that work better. The ideal solution would be to find a a fuel gauge that comes with a matched sending unit that could be retrofitted to a Z gas tank. My stock fuel gauge works perfectly so I left it alone.

100s of posts on this. search "Autometer fuel gauge" BTW it takes some doing to make the aftermarket fuel gauge read correctly. Also, Google "240z autometer fuel gauge" and you will find many write ups on fuel gauges: https://www.google.com/search?q=240z+autometer+fuel+gauge&client=ubuntu&hs=6lG&channel=fs&source=lnms&tbm=isch&sa=X&ved=0CAgQ_AUoAmoVChMIoJ3DsKz9yAIVkJaICh2YnAR2&biw=1344&bih=664

How are you going to use the car? Daily driver?

I always carry a wrench that fits the bleeders on the MC when road testing just for this situation. When the brakes start to seize from having the push rod too long you can unlock the brakes by opening the bleed screws on the MC to relieve the pressure so you can limp home to readjust the push rod in small increments. You may know this, but you do not have to disconnect the MC to adjust the push rod. There is enough flex in the hard lines to pull the MC out and push it aside to access the push rod.

72 240Z SBC 350 Camaro T5 transmission. The grease on the clutch arm pivit ball has become dried out. Is there a way to grease the pivit ball without removing the transmission and bell housing?

I hear Kang and Kodos are good. The other picture is me being being attacked, and badly injured, by a mutant transmission mechanic at a shop on Pluto. All I did was say: "your transmission shifts hard" and he went into a rage..

IF after you have bled the MC (procedure in brake forum), and you have bled the rest of the system, press and hold the brake pedal. If it sinks then the MC is leaking internally. If it just feels spongy then there is still air in the system. Not to scare you, but I had two Wilwood 1 inch MCs fail out of the box. They would not hold pressure. Did you adjust the MC push rod?

Question: have you recently done any wiring changes, modifications or removed any lights?

Good read: http://datsunforum.com/the-scarab-legend-the-original-hybrid-datsun-z/ Look at the engine bay. It has V8 swap written all over it. I don't know how he got it, but the owner of the shop I worked in in fall of 1969 brought one in.

Please note that the wire list is not mine. Perhaps the original owner will comment.

Welcome to the club. Have a great build.

See attached wire list. I do not recall where I got it. 240Z WIRE LIST & FUNCTION.doc
