A brake mechanism for a stroller includes an axle, a wheel and at least one brake fixing seat disposed at an inner side of the wheel. The brake fixing seat includes a brake assembly and a fixing seat. The brake assembly includes a pedal assembly and a brake member. The brake member has at least one abutting portion and at least one brake arm. The brake assembly includes a pushing member for pushing the abutting portion. A brake hub is disposed at the inner side of the wheel. A plurality of recesses is formed on the brake hub and arranged compactly. The axle passes through the pedal assembly, the brake member, and the fixing seat. The pedal assembly is used to drive the pushing member to push the abutting portion and the brake member moves toward the brake hub until the brake arm extends into the recesses.
