Abstract
A friction pad assembly comprises a backing plate having friction material secured thereto, and an anti-rattle spring having a bent portion intermediate its ends, the bent portion seating in a recess in the backing plate. To avoid problems caused by heat when the spring is held in place in the recess by the friction material and located before heat bonding of the friction material, the recess is accessible to secure the spring to the backing plate after the friction material is secured to the backing plate. The bent portion is preferably retained in position in the recess by its own resilience.
