280ZX Brake MC is ready to go! I tore this apart several years ago thinking it would be a short project, but the rebuild kit I had turned out to be for the one made by Tokico (large perforated disc residual valves) and this one is made by Nabco (small rubber duckbill residual valves, see below). I had messed around with trying to rejuvenate the reservoirs. I had read you could cover it in a solution of oxy clean and hydrogen peroxide gel under UV light for 24 hours and it would take the yellow out. It lightened it up, but they’re still clearly yellow. Super clean, though. I also did some chemistry on some of the hardware. The bleeders and reducers for this thing are not common sizes (the reducers are m16x1.0 to m10x1.0) and after two weeks of searching for replacements I gave up and decided to try chemically coating them. I didn’t want to do the hardcore hot bluing or zinc methods because of the chemicals, so I used the rust bluing method. Basically, you soak them in white vinegar to strip off the rust, zinc, and anything else on them. Then you paint them with a paracetic acid / salt solution (8 parts hydrogen peroxide:1 part white vinegar + as much salt as it will dissolve). Dry it with a heat gun and throw it into a double boiler. You’ll see the rust turn black, which is when it turns into iron oxide. Buff it with steel wool and repeat until satisfied, then soak for 24 hours in motor oil. They came out okay. I was hoping they would look more like the pistons, but this is what they look like after four rounds of the process, so it’s going to have to be good enough. Fingers crossed that they don’t just immediately corrode. Then I just had to hone the cylinder, flush it with 91% alcohol, wipe it out, and reassemble. I kept the Tokico 240Z reservoir caps since I didn’t wire the car for ZX caps (PN: 46020-U6701) with the fluid level sensors and don’t have the metal (PN: 46020-K2401) or plastic (PN: 46020-N6000) Nabco caps. Maybe later if I can find a set for less than €53.40. It looks pretty good after test fitting it. I’m waiting for a dust cover and O-ring in the mail, then I can install it and bleed the brakes.

No, no no. Ferris Beuller was in Weird Science. Have you been drinking? I have. 😁

Challenging responses and punctuation at the end of every sentence. I especially liked the "Don't you have a mother?" comment. Now what?
