You don’t see Blackbirds around much anymore. This is a late-model fuel-injected model.
We removed it to replace the disc. There’s quite a bit of brake pad dust accumulated. I heard a rumor that there’s an expert in Hayama who cleans all the holes with cotton swabs after every ride.
If it’s just one a day, that seems doable. Still, that’s incredible.
As brake disc wear progresses, it develops this kind of necking. The top and bottom don’t contact the pad, so the original thickness remains.
Chamfering the top and bottom edges of new pads might make this condition more likely.
Conversely, if it’s necked this much and you install pads without chamfering, the pad won’t contact the disc at all. I think it’s important to match the current condition.
Brake discs, sprockets, and oral care are SUNSTAR.
It’s nice when there are compatible parts available for a vehicle.
We cleaned it up to replace the pads at the same time.
The dirt came right off and the piston operation was in great shape.
