Maybe it's not the brakes. Could be wheel bearings.

Today was a great day to go to the Worship car meet. The weather wasn't too hot, and I found a good parking spot that afforded me some shade for most of the time I was there. There were 2 280Zs, 2 Z31s that showed up, and then there was the time capsule. Sandesh introduced himself to me and said he brought his 1991 Twin Turbo but parked it on the other side of the sea containers in the parking lot. David and I walked over with Sandesh to see his car. It was well worth the effort. Sandesh said he purchased his Z32 with 3K miles in 93. It now has a little over 23K miles. The interior is immaculate, and it wouldn't take too much to get the engine bay ready to win a ZCON Gold Medallion. He still has the original Goodyear Gatorbacks on the rears. I might have to see if I can convince him to buy a Nissan battery. He has been an incredible curator of this museum piece, and I'm so glad he brought it out for us to see. Here is my car with a nice 280Z owned by a friend. And here is the time capsule...

Hot is relative. Use an IR thermometer to say what the temps are. How freely can the fronts spin with the tire off the ground? Shoot a video of you spinning the wheels by hand. Post it on YouTube and link it here.

I've been prompted to start a new thread on this subject after reading - for what seems like the thousandth time - somebody describing the OEM steering wheel on a late 1970 production HLS30UV as "Plastic". No. The OEM steering wheel on the '1969 through 1973 production S30-series Z was WOOD. Real wood. They were manufactured for Nissan by specialist Izumi Motor Co. Ltd, based in Shinagawa, Tokyo. Izumi made a wide range of steering wheels for Nissan, as well as selling their own aftermarket 'sports' stering wheels with a cheeky 'Izumi' engraved script which aped Nardi, one of their inspirations. Izumi used a patented high-pressure heat moulding process. Real wood fibres, impregnated with resin, were laid - following the grain - in a heated mould around the steel hoop of the steering wheel. High pressure, combined with that heat, moulded the wood permanently around the hoop and cured the resin. The result was a wood steering wheel, complete with finger grips on the rear, with no joints or seams. No splinters. My theory is that people found them a little 'plasticky' or just couldn't believe they were real wood, and it stuck. After 50+ years it is hard to shake this off, hence me reading a comment on yet another Bring-a-Trailer auction from somebody who is convinced they are plastic. Evidence: I've cut one up. I'm making a 'special' wheel using this 1970 production Izumi as a base (it was already damaged, so don't weep...) and can therefore show what's under the surface. I'll let the photos speak for themselves...

To your point, @HS30-H, I asked my wife to do a light sanding and stain the steering wheel in my car. She used a regular wood stain and sealed it. The wheel took the stain great. I doubt "plastic" would have faired so well, and my wife, who has stained a lot of wood over the years, confirmed my doubts.

Progress… underside is basically done. Now on to the inside/engine bay… started prepping the brake and fuel lines today. Once I have the engine bay and interior painted, I can start much more reassembly. Seriously looking forward to it… I’m tired of looking at shell. I want a rolling chassis again.

Here's a question. Straight, no spin. Just how much wood do you think is in the rims of these wheels? What percentage of wood, what percentage of "plastic"? What proportions. Ballpark will do. You'll be guessing, of course. So ballpark is OK. I'm looking at the pieces I've chipped off the wheel, and whatever "plastic" is mixed in there is pretty scarce. Most of it seems to be confined to the outer surfaces. I can sand through the shiny stuff and get to the underlying layers of (what I'm calling) wood fibre, and that wood fibre reacts differently than the shiny stuff does. It sands like wood. I splits like wood. It splinters like wood. To all intents and purposes it behaves like wood. The majority component of the wheel rim is wood. In composite form, yes. Of course. I've been pointing that out for years. But wood nonetheless.

You hurt my feelings😒 I love my silver 240 with red interior

You are both correct but you are splitting hairs within an incomplete definition, IMO. There are many ways to process wood, similar to our thoughts of processed cotton or wool. In the manner of manufacturing a wood steering wheel, Izumi used a processing know in the industry as "oriented strand". Oriented strand lumber products have been around since the 1940s. Similar to high pressure lamination techniques, the oriented strand process allows tighter tolerances and strength to a reinforced product like the steering wheel. And, the end product is seamless. Great welding photos of the metal rim and spokes!

We worked on the motor some more last weekend Checked ring gaps All the studs in We checked all the clearances with indicators and verified with plastigage Right now the thrust bearing is pretty tight. I'm not sure we have any clearance. I think we're looking for 0.05 mm. We'll see... @Captain Obvious

Rebuilt the OEM fuel pump earlier this afternoon. I had the dinky-looking aftermarket piece on there, so it was nice to get this one back on the engine. Still waiting on the filter. I ordered an inline fuel pressure gauge too to help me suss out the issue. Going to blow the lines out with compressed air also. Really hoping it's not the screen in the tank.

I think I got it. Originally I stated I bypassed the hazard switch by jumping GY - G in C7. Turn signals did not work. Then I connected c7 back and put in the new relay and it still didn't work. Since I am positive this relay is good I tried jumping the wires in C7 again. Now it works!! Seems like I have a bad hazard switch and a bad flasher relay. You guys are awesome! Thanks for the advice. This was my last fix. After 3.5 years I can get it back on the road!!

Any chance it's the bulb(s) or their sockets? When you say "don't work" do you mean no light at all, or no flashing? I'd put a meter on the pins in the bulb socket. Sometimes they look okay but don't actually contact the bulb terminals. Plus you can test power supply and ground. A look at the wiring diagram will show which pins do which.

Can't wait to see what is new: Keith

I might just as well quote myself for every Bring A Trailer S30-series Z auction, because the same sticky swamp of 'Series' and 'Model Year' conflation and claptrap comes up every time. Sure enough, on the regular, it rears its ugly mug on the 919 12/70 HLS30UV auction currently running.

Sadly, but almost inevitably I think, Izumi was bought up and merged into the global giant Autoliv group some years ago. The old Izumi factory still continues in Atsugi, Kanagawa prefecture. It would be nice to imagine they had some sort of corporate archive.

My KPGC10 Skyline 2000 GT-R track car also wears an (aftermarket) period IZUMI steering wheel, similar to the Datsun Compe style vinyl with moulded stitching detail. Note the 'Nardi' style 'Izumi' signature engraving on the RH spoke:

No matter what material, those photos could almost be turned into a piece of art! Very well done! Mike

Hi Alan, that is a great anatomy of our steering wheel. It is wood !Even it appears wood more than I expected. I remember when I asked if our steering wheel is wood , Mr.Matsuo said it is wood compressed with a very high power added some plastic (or a kind of material) . Alan , do you see “compressed “ phenomenon like Mr. Matsuo said ? I think Datsun 510 has a same steering wheel, I am curious about if there are any discussions about same thing among 510 owners ? I want to ask it directly to an engineer of IZUMI but maybe impossible… Kats

And some more non Datsuns..

Got my 240Z OEM door mirror from local Nissan parts department shelf I have stocked with potential use stuff. Thought about cataloging all of them with my part number "supersedes" master list I have put into use. The 1st photo shows the superb quality of the mirror. It's no surprise Nissan choose to save weight and the potential for 7 years of bad luck without an additional right side mirror.

I wish I knew, only thing I did was add the uv dye to the system. Clearly I will be retesting, I am using the fluid from the same bottle, I should have sniffed from the tail pipe to confirm color change, will do that next time. I will conduct more test over the coming days. Thing is IIRC I had the same thing happen on the N42/MN47 spare engine, failed at 1st then tested fine later and ever since. REALLY bugs me but if I can't get it to fail again (and remember it never overheated when it did indicate fail) then I will take the W, don't want to look a gift horse in the mouth.

Found the steering wheel in a junkyard on a 240z. I acquired 2 on them that way and bought one for $165. This one in the pics was the worst condition one of the batch. It was really bad. I decided to attempt a refurbishment of this one as a test and it came out great so I didn’t bother with the other one. I donated the one I bought to a friend that has helped me out on this build. Will probably sell the last one I have. Here is what it looked like when I got it.

One of my favorites too. The white with blue interior is the other one. They look best in your driveway/garage hopefully paid for.

Wrapping up the interior. I’m pretty happy with the outcome. It’s not perfect but it has come a long way. I wish I had great pics of the interior to show the before and after. The bottom line my car had no interior and no seats when I bought it. Everything is new or something I either bought or salvaged. The only interior pieces that I had were the plastic panels that go around the rear quarter windows. The headliner was also in good shape and required no work. There was no vinyl on the shock towers or wheel wells. I salvaged mine off a junked Z in a salvage yard. You can see in the before pics the interior was just bare metal. Still haven’t figured on the center console arm rest mechanism. I have all the parts (springs and wires ) just haven’t figured out how is works yet. I also need new sun visors, or to have mine refurbished.

Also has the original Yazaki spark plug leads, unusual to see these 51 years after the car was built.

The steering wheels on my Aston Martins are wood rims, made from shaping a solid piece of wood. These are the traditional style of wood wheels built this way for a hundred years or more. When composites came along and combined resins/plastics with various reinforcing materials the rim was shaped in a mold using pressure and heat. Not many people consider these "wood" in the traditional sense. Hence, its understandable why some people call these plastic...and they are partially correct. I would not consider the wheels in my 240Zs as wood but as a molded composite. Trying to correct people and their use of various naming conventions becomes quite petty, we are all correct but in various different ways.

The wheels are actually a composite using wood fibers as the reinforcing element and the resin being the plastic. It is understandable some people refer to them as "plastic" rather than wood. Generally a "wood" steering wheel would be made up of shaped pieces of solid wood attached to a metal frame.

I've had a brief look at this one and so far it looks very genuine. It may sell for real $s.

Here we go again. Another one family, low mile 70. https://bringatrailer.com/listing/1970-datsun-240z-86/ Immediately jumped to $15,000..
