As expected, it’s great, right? Z1R inspection AP2696 caliper CP3125-6 master OH

It looks sleek. The Z1R. I think it’s an eternal classic.

I was thinking about doing the inspection, but then the fluid started seeping… and I think even that tank stain has a certain charm to it.

When I removed the master cup… well… it was in quite a rough condition (;∀;)

It’s scary, but should I remove the top too… I’m glad I bought the 26mm box wrench (Yahoo Auctions).
If you delay brake fluid replacement like this, it’ll rust like crazy, so be careful!

Since it’s an aluminum caliper, it’s not corroded, which is a relief.

We also need the seal ring, so CP2696-6RK is required. I almost made a mistake there—safe!

It’s been a while since I’ve disassembled a CP2696.
The piston heights are different on the right and left—that’s kind of neat.

I took some measurements for reference.

There aren’t many component parts, which is helpful.
Lockheed has a nice design, but the piston operation is poor.

I also use a CP3485-8SO, and when I went from an old Brembo racing model to an OH and swapped it, I thought “hmm, it’s subtly dragging a bit.”
Well, the seals are pretty effective… Brembo really is great.
But AP Lockheed has such a nice design that I understand why people choose it.
If the difference is minor, I’d pick “design over performance” too.

I haven’t used it much lately, so maybe I should use the ultrasonic cleaner more actively… but it gets really hot.
It cleans well, but it takes so much time that I’m not sure… Well, it’s piping hot.

A long rear fender looks cool, you know?

I think bikes from this era look a bit cooler with a rear fender, based on my image of the superbike regulations back then.
