What is the Brake drum: The brake drum is a type of cast iron shaped like a tambourine, which is fixed with the tire and rotates at the same speed. When braking, apply oil pressure to push the brake shoes to contact the brake drum inner rim, we can control the rotation of the wheel to achieve the purpose of braking by the friction force comes from contact.Structure of drum brakesDrum brakes are a brake system with brake drums (rotor) which rotate with the wheels. Inside each drum arebrake shoes fitted with brake linings (friction material). Pistons (pressure mechanism) press against the drumsfrom the inside to generate braking force, thus making is possible to decelerate and stop the vehicle.

How drum brakes workWhen the driver steps on the brake pedal, the power is amplified by the brake booster (servo system) andchanged into hydraulic pressure (oil-pressure) by the master cylinder. The pressure reaches the brakes onthe wheels via tubing filled with brake oil (brake fluid). The delivered pressure pushes the pistons on thebrakes of the four wheels. The pistons press the brake linings, which are friction materials, against the inside surfaces of the brake drums which rotate with the wheels. The linings are pressed on the rotating drums,which in turn decelerate the wheels, thereby slowing down and stopping the vehicle.Main part number of Brake drums:Middle east and euro market: 3054230401,3464230501,3464230601,0310667290,0310667560,0310677630,1599012 etcNorth America market :3600AX ,2983C ,3721AX ,3800X ,68765,67518,66893,66864,62200 etcEast south Asia market : 43512-1710,43512-4690,43512-5000,42431-37080,42431-36190,MC807783,MC895621 etcRussia market :53205-3501070,64221-3502070,5336-3501070,677-3501070,6430-3501070,9397-3501070 etc South Africa market : TD0403, TD0334,TD0629,TD0103,TD0119,TD0575,TD0630,etcAlso, we produce the brake drum according to the sample and drawing.•100% dimensions runout and DTV inspection•Material physical and chemical inspection•Test density, flatness and parallelism•Test performance and noise/NVHAdvantages:With more than 10 years of experience, we know exactly what you need; Strict quality control in raw material selection, production line, and pre-packing, which ensures the reliableproduct quality as per customer's request.
