Caliper Brakes

From Bike Collectives Wiki

Also known as side pull brakes, there are two types of caliper brakes.

  • Single Pivot - The simplest form - both brake arms pivot about a single bolt that usually attaches the unit to the frame as well. Single Pivot Calipers also "track" an out of true, and or mis-dished rim without issue.
  • Dual Pivot - Each arm has it's own independent pivot bolt, and the unit attaches to the bike with a separate bolt. These can provide more mechanical advantage then the Single Pivot Caliper Brake. However, Dual Pivot Calipers perform poorly in situations where there is a mis-dished wheel, or a wheel out of true.
