Brake cable ferrules do one job: keep housing ends from splaying under compression. When you squeeze the lever, the outer housing wants to mushroom where it meets the frame stop or brake caliper. A ferrule contains that force, maintaining a clean cable path and consistent lever feel. Skip the ferrule and you'll notice it immediately—spongy response, cables that need constant adjustment, housing ends that look like they've been chewed.

These SRAM Pit-Stop ferrules are brass, which handles the compression loads without cracking or deforming over time like plastic ferrules can. The 5mm inside diameter fits standard brake housing from any manufacturer—Shimano, Jagwire, Yokozuna, whatever you're running. Brass also resists corrosion better than bare steel, which matters if you ride through winter or wash your bike regularly.

The 10-pack quantity makes sense for home mechanics. A typical brake setup needs four ferrules minimum—one at each end of the front and rear housing runs. Add a few more if your frame uses inline stops, and you'll burn through ferrules faster than you'd expect.
