Abstract:
1. A pad assembly for use in a disc brake, comprising: a carrier plate; a backing plate having two sides; at least one friction pad secured to one of said sides of said backing plate; the other of said two sides of said backing plate being mounted on said carrier plate by an intervening spring connection for enabling movement of said backing plate relative to said carrier plate against action of said spring connection in response to application of an external braking force to said disc brake in operation; a plurality of force transmitting members secured to one of said carrier plate and said backing plate and projecting therefrom into position to engage the other of said carrier plate and said backing plate in response to said relative movement between said backing and said carrier plate exceeding a threshold limit, wherein the force transmitting members are operable to transmit the applied braking force between said carrier plate and said backing plate, and wherein at least two of said force transmitting members are generally equiangularly arranged about a geometric center of said backing plate; and wherein said spring connection comprises one or more conical spring washers encircling each force transmitting member.
