1. A brake pad retainer system for a vehicle disc brake comprising a calliper bridge and a calliper housing supporting brake pads on either side of a rotary brake disc, wherein the system is arranged to hold one brake pad in position relative to the calliper bridge, the retainer system comprising:
a retainer bracket arranged parallel to the brake disc axis and extending across a back plate of the brake pad, and
a retaining spring arranged along a radially outer portion of the back plate and extending between the retainer bracket and the back plate;
wherein the retainer bracket has an angled surface arranged in contact with a corresponding first angled surface on the retaining spring;
wherein the retaining spring has a second angled surface arranged in contact with a corresponding angled surface on the radially outer portion of the back plate; and
wherein the angled surfaces are arranged at an acute angle relative to a plane parallel to the brake disc rotary axis, which angle is converging with the rotary axis of the brake disc in the direction of the brake disc.
