The invention discloses a novel ratchet wheel type automobile brake adjusting arm device which comprises an adjusting arm shell, a ratchet wheel, a ratchet block, an adjusting hexagonal cap, adjusting amphoteric gear teeth, an impact shaft and an impact hole, the adjusting hexagonal cap is rotated clockwise, the adjusting amphoteric gear teeth drive the ratchet wheel to rotate, the ratchet block is ejected upwards, and the ratchet block skips one by one, so that the ratchet wheel is driven to rotate clockwise, and the impact shaft is driven to impact the impact hole. When debugging personnel knock the impact shaft with a hand hammer, the head of the impact shaft rapidly ejects the ratchet block upwards along the impact bevel angle, meanwhile, ratchets on the ratchet block are separated from the ratchet gear to generate tooth skipping, the camshaft rotates reversely by one tooth, and the ratchet wheel and the ratchet block are locked. And the brake clearance between the brake friction plate and the brake drum
