A manufacturing method of a brake pad with a good braking effect relates to the technical field of brake pad production. The brake pad comprises a friction material and steel back. The friction material comprises the following raw materials: phenolic resin, cis-polybutadiene rubber, carbon fiber resin, talcum powder, zirconium silicide, aluminium carbide, barium sulfate, graphite, molybdenum disulfide, copper silicide, steel fibre, silicon carbide whisker, aramid fiber and molybdenum fibre. The manufacturing method comprises the following steps: burdening, mixing materials by a water method, carrying out pre-press forming and primary heat treatment to produce a friction material workblank; carrying out mild heat treatment, putting the friction material workblank into scalding hot oil to undergo scaling for 3-5 s, taking the friction material workblank out and cleaning with alcohol, and airing; carrying out steel back shot-blasting, and gluing steel back; carrying out hot press molding; and successively carrying out secondary heat-treatment, grinding, slotting chamfer, sand-blasting, and gluing silent blades. The brake pad of the invention has high strength, is oxidation resistant, and has long service life, good heat stability, high friction coefficient and good environmental protection property for production.
