The commonly heard brake caliper cleaning should be done from time to time, including as a way to check the condition.
You can see firsthand how much brake dust has accumulated and the condition of the piston seals.
Brake caliper cleaning is basically a messy and time-consuming job.
There’s no doubt that brakes are an extremely important component.
It’s no exaggeration to say that you’re entrusting your life to this component, so rather than doing it reluctantly, checking and cleaning it with genuine care and affection will be more effective.
The piston in a brake caliper doesn’t have a large stroke.
It’s constantly exposed to heat and brake dust in a harsh environment.
On the visible piston portion that doesn’t move much, dust stubbornly builds up. You need to remove all of this dust.
That’s where a piston rotator comes in handy.
It’s used to clean areas of the caliper body that aren’t visible.
By rotating it, you can also check the condition of the piston seal to some extent.
If the seal condition is good, you can rotate the piston smoothly.
But if the condition is poor, honestly, it’s stiff and heavy.
After cleaning is done, you push the piston back in by hand, but if that’s heavy, you should consider a caliper overhaul.
If you work the caliper piston in and out with some manipulation, you can recover some function.
But that effect is temporary.
If you’re going to spend time on that manipulation, it’s more efficient and faster to just do a caliper overhaul.
If you notice the caliper piston action is stiff, don’t hesitate to do a caliper overhaul and refresh the seals—your motorcycle will be easier to push and pull, and brake control will improve dramatically.
I think it’s good to check it at the right time.
