Let’s do some brake maintenance.
Hot water is really convenient—it dries quickly and cleans dirt well.
Since it’s an anodized aluminum caliper, there’s no corrosion and it’s in great condition. The seals are pretty stiff though.
Calipers definitely improve when you wash them, but the seals never quite match a fresh set.
When you notice the return action getting sluggish, go ahead and swap in fresh seals when you change your tires.
It looks a bit beat up. We tapped it with M10-P1.00 and it held up fine.
We don’t have a helicoil for this P1.00 pitch, so we were lucky it worked out.
We’ll do a quick inspection as a reference.
Seal inspection—no issues.
We want to pack metal-rubber sealant all the way to the back of the seal. The action is noticeably better now, both going and coming back.
We already did the rear recently, so we’ll put that time toward something else.
The dual-piston rear caliper pad shim has a relief on the leading side and the shim plate covers the trailing side.
Since the leading side gets inserted, it might be designed to prevent uneven wear. Different makers do it different ways.
