A novel brake pad and a mold and method for preparing the brake pad. The invention proposes a new type of brake pad, which includes a friction material block, and the friction working surface of the friction material block is formed with a plurality of stepped working surfaces with different heights and gradually raised or lowered. In this way, the step-by-step working surface of the present invention forms a step-shaped chamfer, which can effectively reduce brake noise and efficiently remove wear debris, and as the The consumption of the friction material block increases the friction area with the tire brake disc step by step, so that the braking effect will not be poor due to the smooth friction surface after long-term use. Therefore, the braking noise of the present invention is low, the chip removal effect is good, the friction effect is good, stable and durable, and has strong practicability. The invention also provides a mold, which can integrally form the brake pad, has no bad demoulding, high efficiency, strong bonding force, stable quality, low cost, material saving and no industrial waste. The invention also proposes a method with clear and concise steps, which can efficiently prepare integrally formed brake pads.
