Oh how I hate rebuilt components that I did not do myself.

That helicoil should not be in the sealing path for brake fluid. The seal should be made at the beveled surface inside. Assuming, of course, that the helicoil is installed straight and square to the seal, and is actually the correct metric thread for the application..... No guarantees on any of that!     I hate rebuilds!!

The helicoil is installed wrong.  I think too deep or something, it ruins the brake line it attaches to.  Also I have stainless transfer hoses, which I think I need to clean up the fittings.

Great... Sounds like the helicoil was installed by the same guy who but my rebuilt starter together. Glad you found it before it was too late.

So, since they claim the helicoil is a "normal repair", are they going to take that one back for refund? Or are you stuck with the cost?

How does it "ruin" it?  Might be a clue.  But, if you just don't like helicoils, or any repairs at all, it doesn't really matter.

Helicoils are just normal repair for any screwed up threaded hole.  Screwed up threads are common, that's why "helicoil" is a well-known word of the trades.  The other thread insert guys probably hate that.

I don't like helicoils:)

 

It tears up the flange area on the brake line.

No offense, but once you understand how they work they're not bad when properly installed.  Your case sounds like poor installation.  It's not the thread insert itself, it's the way it was installed.  So, you're right, it was a "half fix" but it's a very common fix.  That's why they didn't tell you, probably.

You might find thread inserts in some of the other holes that didn't leak.  Wouldn't be surprising to find them in the Posi-Quiet calipers either.  "Original equipment" just means it started on a Nissan, before they rebuilt it.  They didn't cast and machine their own calipers.  Notice that they show new pistons, but not new calipers.  Better check.

Sorry.  I'm a bubble buster.

 If the Heli-Coil is too long and interferes with the sealing surface, they are available in different lengths. I've fine tuned the length of them before installation in the past.

[duffymahoney]

Thanks guys.

 

I think it’s a lazy fix. Plenty and plenty of Toyota cores to be had. I just like to have things done correctly. 

 

The posi quite is still a stock core (used) but everything else is new and fully tested. I’m sure it’s better then most rebuilds 

[duffymahoney]

Installed the front zinc centrics calipers. I ditched the stainless lines from the caliper to the coilover tube. Went with traditional lines. No leaks!

I got my centric rears that were back ordered.  They are works of art.

Those look good. Very unusual to see parts that nice from retailers

[Captain Obvious]

Rebuild, right?  They probably forgot to put the piston seal in.   

Don't laugh... I've seen it. Not on a Z, but I've seen it.

[duffymahoney]

Well I drove the z! She runs a little rough.  I think electronic ignition, check timing and fiddle with the carbs are next.  Also install exhaust.  Boy is it loud with nothing:)

I had to take the brake switch block apart.  It was gummed up and causing some issues.  I also screwed up on the 1" Mc push rod adjustment.  So it was stopping me from bleeding correctly and also gave me terrible brakes.  Re adjusted and it's working well now.  I could use a little more brake, but I think that would mean a bigger booster.
