Have you checked to see if the "reaction disk" inside the brake booster has fallen out/into the booster? That is the leading cause of the problem you have been having with the brakes.

Nope, I have not checked that. I have not heard of a reaction disk before.

I wonder if I should just replace the booster with a used one the next time I happen to find a suitable replacement from a wrecking yard


Thank you Ted!

The reaction disk is a rubber puck looking thing that is between the booster diaphragm and the master cylinder.I had it happen with the booster in my 260Z, I was able to shake the booster around enough to get it out.

Check out Hybridz, there was a big thread about it several years back.

cool. I'll check that out.

 

For anyone else reading this, here is the link to a good thread on Hybrid Z about the booster and reaction disk

I messed with the key and used some penetrating oil for quite some time but eventually gave up. I'll have to do some research on this one. Not sure if I'll be forced to replace the entire ignition assembly now.

 

They do make affordable aftermarket options these days?

I've had this problem so many times that when the stickiness begins, I just go ahead and order a new one...   ^_^

That's one way to do it! I guess you won't have a Nissan key anymore.

 

Can I use the internals from a 280ZX ignition and put it in the 280Z? I have a ZX parts car with key.

 

In fact, if I can just force this key out, I've got the correct key for the tumblers (as long as I don't destroy them)

You can, that just costs a little more...   ^_^

I wouldn't be at all surprised if the whole switch assembly will swap straight over. There was very little variance in the different switches.

I took my ignition lock to a locksmith ( Always safe and lock on 4th in Olympia to be exact) and they pulled it out no problem.. Me and Nelson dropped off two of them one morning, and they called that they were done before we got done with lunch..  They both were from the dreaded wrong key in the hole ,,,,,,,,,,,, deal.

 

Was just under $60. for both i think. 


So somehow while i was driving back from Eaglerock swap meet i somehow caused YOU to post this,,,, do really think members on this site are that stupid to believe i caused it??

I can try lock bumping to remove this key, possibly adding some graphite powder lubricant.

Or put some vice grips on there, yank the key out and then see if the proper key inserts at that point. If I do this and the tumblers are destroyed then I'll try using my 280ZX tumbler assembly. (free method)

 

At the very least I can just disconnect the electronic switch at the back and use that to start the car.

 

Thanks for the suggestions. Once I get this key figured out I'll be back to working on the brakes.


Thank you Ted!

I got the key situation resolved.

 

I removed the keyring, clamped on the largest vice grips I had, and just pulled the key out by force!

I then put plenty of graphite in the keyhole and inserted the correct key for this car. I had to tap the key a bit to gently get it set in there all the way. Eventually I was able to turn the ignition OFF and remove the key. It now opperates normally with the correct key.

 

No more testing other Datsun keys on this ignition!

 

Most weekends its raining so I haven't done anything still with figuring out why the car won't start and then I'll look at the brake booster.


Thank you Ted!

My good friends Moog and Marty suggested I try a 2015 Toyota Hilux brake booster with master cylinder in my 280 Zed

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.

You're going to skin a few knuckles, stand up too fast and bump your head, hunt around the floor for the nuts and bolts you dropped, invent a few new cuss words and when you're finished you'll say "That wasn't so hard after all!"

I did more research on that Hilux booster. It looks to be the 2010-2015 model and the booster only fits that year range of Hilux and also the 1972-73 Toyota pickup. (strange, huh?)

No other cross-reference so I'm not going to be able to find one in a wrecking yard in the USA. That leave me with the only option to buy one new for over $120. At that price range I can pretty much buy any booster.

 

Other upgrade options include the 1974-78 280Z 2+2 booster. (large than 2-seater booster) or even the 1979-81 280ZX booster (turned 180 deg)

 

I think it will depend on what I find in a wrecking yard over the next few months. Either of those Z-car booster swaps sounds good to me and both work with the 280ZX brake master cylinder "upgrade" as well.

 

Also, my Z-car's fuel pump isn't pumping ... again


Thank you Ted!

Are they not the same as a USDM Tacoma booster?

That would make the most sense but it looks like they are not the same.

 

However, the differences could be very minor and might not get in the way of an S30 install. I just don't know at this point.

Car-part.com is showing a few in your area for around $80 used. Is it with the gamble? 

 

Rockauto has some for the '72-73 truck for around $100.

I found an R200 Limited slip differential this week in a wrecking yard! Also got some coilovers from the same 300ZX turbo. (rear only)
