ABSTRACT:
A retraction seal (32) for a disc brake is disposed within a caliper groove (34). The retraction seal (32) cooperates with a forward wall (42) of the groove (34) to define a space (72) which substantially prevents the retraction seal (32) from engaging a radially inner edge (80) of the forward wall (42) during braking, thereby preventing nibbling of the retraction seal (32).
