1. A brake caliper for a bicycle, comprising:
a housing configured to be installed on the bicycle, the bicycle including a disc attached to a wheel of the bicycle;
a brake pad installed within the housing, the brake pad configured to move between a braking position and a non-braking position, the braking position being a location within the housing where the brake pad contacts the disc in a state where the housing is installed on the bicycle, and the non-braking position being a location within the housing where the brake pad is further from the disc than the braking position in a state where the housing is installed on the bicycle; and
a biasing member configured to bias the brake pad in a downstream direction within the housing when the brake pad is in the non-braking position, the downstream direction being parallel to a direction of rotation of the disc when a wheel of the bicycle is rotating to move the bicycle forward,
wherein:
the housing comprises:
a first housing wall that is located in the downstream direction relative to the brake pad; and
a second wall that is located in an upstream direction relative to the brake pad, the upstream direction being opposite the downstream direction; and
a downstream-facing surface of the biasing member is convexly shaped so that the biasing member contacts both the second housing wall and the brake pad while also maintaining a space between the biasing member and the second housing wall.
