Let’s do some self-service point maintenance. The aluminum fittings look like this, so you need to be careful.
Amazingly, it doesn’t leak—I’m impressed.
First, the heart of the four-cylinder: synchronization.
You want the controls to be smooth. It’s nice when you can focus just on riding.
Too bad…
The situation is so-so, but the piston movement is nice.
I went with the newer setup.
If you can help it, don’t use thread locker.
The pin on the left caliper is stripped and won’t come out. There’s nothing I can do from the outside…
Split it, welded the nut, and the pin broke.
Welded again and it broke again.
So I decided to pry it out right at the edge.
You’d think I should use a milling machine, but I took a shortcut with the drill press. I guess when you get old, things just work out somehow.
Got it out—thank goodness.
I don’t want any chips in there, so let me check.
I’ll clean up the pad spring too.
The other side has a crack… hmm.
