I am putting my old cane creek 200 sl brakes on a different bike. I've had these brakes sitting around for awhile and I don't recall any problems the last time I had them on a bike.

But, on this new bike, the full calipers themselves loose, both front and back brakes, and has a wobble to it. I'm not getting great braking power and suspect this is why.

Could these brakes be the wrong size for the frame? It's an older Legnano steel road (pretty similar to the 80s bianchi style road frames), and I am not sure how to figure the compatibility.

  • What do you mean middle piece loose? did you not tighten teh caliper down? Did you use the right length centerbolt/ recessed nut?

    Yes you're right - excess movement will severely limit your braking power. Can you please add a photo to your question showing what you see?

  • I'm wondering if teh old bike and new bike have different mountings for the brake calipers. More modern bikes have a recessed chicago bolt fitting into a slightly larger hole, whereas older bikes would have had a nylock nut onto a bolt through a smaller hole. Larger hole gives more wobble.

Some brake calipers have a small locking screw with which you can adjust the rotation of the brake caliper without having too loosen the bolt with which the caliper is mounted to the frame. Check if your caliper has such a locking screw and if tightening it helps. It should be approx 2mm in diameter.

The afore mentioned locking screw can be seen here: https://www.parktool.com/assets/img/repairhelp/dual27.jpg
