Abstract
This invention relates to a pad retraction spring for use in a disc brake assembly. The pad retraction spring is operative to move the friction pads from engagement with the rotor when the friction pads are in a non-braking position. The pad retraction spring is effective to apply a first force against the friction pads when the friction pads are new, and effective to apply a second force against the friction pads when the friction pads are worn. The second force is greater than the first force, and at least one of the first force and the second force by itself is not sufficient to move at least one of the friction pads from engagement with the rotor when the friction pads are in the non-braking condition.
