Abstract: A brake shoe return mechanism applied in a bike or motor vehicle has a gap disposed each on both sides of a brake lining of each brake shoe, and a lug is disposed at each arm extending from a return spring to both sides of the brake lining to penetrate into the gap for securing the spring in place to avoid mal-position of the return spring and ensuring normal operation of the brake.

Abstract: A brake drawing system applied in bikes and any motor vehicle provided with handbrake and pedal driven brake operates by having a pull rod to drive a push rod to engage in linearly reciprocal motion for activating the brake; a brake lever pin on the pull rod constituting transmission between push rod and pull rod; the push rod penetrating an adjustment bushing on the brake lever pin to adjust brake openness by changing relative positions between sleeve and brake lever pin without interfering with the push rod to maintain pull rod openness as adjusted.
