汽车制动零部件批发供应商

Automotive brake systems comprise multiple replaceable wear-part categories that generate recurring wholesale demand: brake pads (friction material bonded to a backing plate — the highest-volume replacement item in the brake system, requiring replacement every 25,000–70,000 km depending on driving conditions and material grade); brake discs/rotors (cast iron or composite ventilated discs requiring replacement when worn below minimum thickness or warped); brake drums (cast iron drums used in rear axle drum brake systems on economy and commercial vehicles); brake calipers (hydraulic actuators that press the pads against the disc — replaced less frequently but a significant aftermarket item for seized or leaking units); brake lines and hoses (steel and flexible hydraulic lines connecting master cylinder to calipers); brake master cylinders and wheel cylinders; and brake hardware kits (springs, clips, shims, and pins supplied as a kit with pad replacement). The global automotive brake parts aftermarket is dominated by manufacturers in China, Germany, and Taiwan, with Chinese manufacturers supplying the majority of value-tier and economy aftermarket supply, German-origin brands (Bosch, Continental, TRW/ZF, Brembo Italy) supplying the premium OEM-equivalent tier, and Taiwanese manufacturers (Federal-Mogul, Allied Nippon) competitive in the mid-market.
