ABSTRACT:
A brake adjuster for a pedaling training machine comprises a base, a position plate and a U-shaped magnetic arm combined together. The position plate is combined on the base with a pivotal shaft to be tilted up at the front and tilted down at the rear and can recover its horizontal position by elasticity of a spring pinched between the position plate and the base. The U-shaped magnetic arm is combined on and moves together with the position plate, having two permanent magnets on both sides of an intermediate opening. An iron turning disc fixed on a shaft of a pedal in the pedaling training machine is positioned to have its circumferential edge and its two sides extending for a preset distance in the opening to face the permanent magnets so as to stop the turning disc by a hand brake controlling a main shaft combined with the base.
