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.
Claims9
A friction pad assembly comprising a backing plate having front and rear faces and friction material secured to said front face, an anti-rattle spring having a bent portion intermediate its ends, and a recess extending across the width of said backing plate from the front to the rear faces thereof, said recess having an opening which extends outwardly through the edge of said backing plate between the front and rear faces thereof said opening being smaller than the largest dimension of said recess, said bent intermediate portion of said spring being seated in said recess and forming a positive connection therewith by the inherent resilience of the bent portion, said recess and said bent portion forming the sole connection between said spring and said backing plate, said recess being accessible to secure the spring to the backing plate after the friction material is secured to the backing plate, said spring being removable from said recess without deformation of said backing plate.
