Recently passed inspection on this CBR600F4I—brake disc and pad replacement and other work.
Original brake disc. Sunstar didn’t have a replacement option, so we went ahead and swapped it out while we had the chance.
A torque wrench is necessary, but you also need the feel of hand-tightening. If you could just use a torque wrench and pass the buck, that’d be easy. We have a torque wrench tester and check it one or two times a year. I wonder if there’s a tester for the torque wrench tester. Overconfidence leads to complacency, so we stay careful.
The tightness of the axle changes how heavy the rotation feels, so we make a small adjustment. It’s not just about replacing it and calling it done—positioning it where it moves smoothly lets it perform at its best.
The dirt buildup is pretty moderate.
When cleaning the caliper, I almost never use a toothbrush. I find it faster to apply plenty of cleaner in one stroke.
For the inside, I use a round brush—a decent one that costs a few thousand yen. Cheap ones shed bristles and wear out fast, so they end up costing more in the long run.
We also did a fluid change. That’s all for today.
