Abstract:
1. A two-piece brake shoe for use with a brake assembly including an inner cylindrical surface that rotates with a wheel such that torque applied to the inner cylindrical surface is transmitted to the wheel, the two-piece brake shoe comprising: a first piece comprising a first piece body having a free end and a first connecting portion, said first piece body being elongated and curved; and a second piece comprising a second piece body having a free end and a second connecting portion, said second piece body being elongated and curved; said first connecting portion being adapted for being fitted to said second connecting portion to form a brake shoe body that has a first free end and a second free end defining a gap therebetween, said free end of said first piece defining said first free end and said free end of said second piece defining said second free end, said gap of said brake shoe body being adapted for engagement by an actuating mechanism capable of spreading apart said first and second ends to thereby place the brake shoe in an engaged condition wherein the brake shoe exerts a braking force on the inner cylindrical surface, said brake shoe body being resilient such that it can assume said engaged condition and a disengaged condition wherein the brake shoe does not exert a braking force on the inner cylindrical surface, and said brake shoe body being self-biased toward said disengaged condition.
