CB1100 SC65 Sunstar Brake Disc EM525WL/WR (Semi-Floating)
Both the pads and disc are now brand new. They’re starting to bed in a bit.
With modern BD material and sintered brake pads on a single-piston setup, the braking effect is more than adequate.
The original stock setup had a used disc and pads, so there’s no real comparison, but old pads and discs lose their bite even if there’s material left—they’re just not fresh anymore.
Once new pads and disc are properly bedded in, you really feel that “whoosh”—the bike slows down hard and fast.
When bedding in, the basic approach is to avoid dragging the brakes. Instead, do repeated cycles of gentle braking—warm them up, cool them down, warm them up, cool them down. That’s the way to go.
I think the stock calipers are better than fitting cheap, thin aftermarket support brackets (though it’s a shame some calipers have limited pad options).
For absolute braking performance, I’d say start with the disc and pads.
For control, it’s the master cylinder and hose.
With calipers, pad selection and piston seal responsiveness are critical. You also have to be careful not to go too large with piston diameter.
Stock components are well thought out, and small upgrades often maintain good balance.
