I was remembering a thread recently that discussed blade refills for the factory 240z wiper frames. Am I remembering that correctly? I looked through several pages of electrical post and tried several Google searches of the site but can't find it...

I use Trico 44-200 Plastic Windshield Wiper Blade Refills. I just cut them to length and fit them into the existing blades. They come up on EBay fairly regularly.

Could this be it that I posted a couple of years ago?

Yep, I went with the OER F309 blades for a perfect fit with the original equipment twin-rib frames. They are not cheap at $18/ea.

Yes, that is the one! Two years, times flies...

So some more progress and some lessons for today.

My brake light was always on unless I pulled the signal wire off the safety brake failure switch. The parking brake wouldn't light up the brake light either.

After pulling the sensor and exploring some and stealing a switch off the brown Z and opening it up some Cody could see it. We determined the sensor threaded in too far.

I rebuilt this in Jan 20, 2018. I used a small viton o ring instead of the black ring on the end of the sensor. It should probably be a small hydraulic D ring instead. If it threads in a hair too far it will close the ground circuit all the time. We took the black ring out of our stolen switch and that fixed the always on brake light.

The parking brake switch had to be wire wheeled to make it work but we still didn't have a ground path. So that meant we had to pull the bolts out of the parking brake mechanism and clean off some paint so that we had continuity. Then the parking brake switch lights the brake light as it should. :)

So the lesson here is very similar to Chuck's steering wheel anecdote. If you paint everything, you're electrical might not work!

I also made a little heat shield for the 123 ignition. I have heard that heat from the header could kill the electronics. It's flimsy but I will redo it when I decide what I want the finished product to look like

I also worked on my parking brake adjustment. Using all the adjustment available the handle was almost out of travel. So I bought some 10mm OD 5mm ID aluminum tubing off Amazon and added a small section of tubing to remove some of the slack in the system. I used some heat shrink to prevent it from rattling around. It works much better now. Five clicks and it's tight at about a 45 degree angle.

Charles. When doing brake systems, you should use EPDM rubber. Preferably, choose peroxide-cured EPDM, as it offers better resistance and holds its form longer than the sulfur-cured material. Viton (FKM) is not suitable for brake applications, as it will eventually degrade when exposed to brake fluid.

I have successfully used O-rings on that switch before. It is unusual that yours travels too far and makes contact with the shuttle.

I have the sizes somewhere if you want them.

Chas,

That's for the direction on Oring material

My switch is different than the one you posted. I wonder if any of the Orings are the same?

Charles, Nice family photo in the garage for the Build Threads category! I'll bet the kids are a bit bigger now.
