A drum brake apparatus (11) includes a wheel cylinder (15), an extension mechanism (21) disposed in the wheel cylinder, and an electric actuator. The wheel cylinder (15) pushes adjacent ends on one sides of a pair of brake shoes (25, 27) disposed in a brake drum (29), at a tip portion of a first piston (39) and a tip portion of a second piston (41) by fluid pressure, to thereby expands the pair of brake shoes (25, 27). The extension mechanism (21) drives the first piston (39) and the second piston (41) in a direction away from each other. The electric actuator rotates the extension mechanism (21).

A brake piston includes a piston pocket. The piston pocket receives a nut that is axially movable along a center axis. The nut is restricted from rotating within the piston pocket when a torque due to a frictional engagement between a nut seal and an inner pocket wall, one or more projections, or both is greater than an input torque at the nut. The nut is rotatable within the piston pocket when a torque due to the frictional engagement between the nut seal and the inner pocket wall, the one or more projections or both is less than the input torque at the nut and is less than the torque due to the frictional engagement between the piston and the piston seal.
