Car brake drum is suitable for Toyota HILUX

Car brake drum is suitable for Toyota HILUX

Basic information of the product

OE NO.: 42431-0K130

Applicable Brand: Toyota, Lexus (imported), Weizmann (imported)

Outer diameter: 344.5MM（mm）

Inner diameter: 108MM（mm）

Thickness: 76.1MM（mm）

Material: HT250

Advantages of the brake discs

1.Accuracy hole diameter and disc body determination, drilling and marking process, increasing friction and effectively shortening braking distance

2.Dynamic balancing technology rejects shaking: Automatic intelligent numerical control, heart balancing technology, high-speed braking without shaking

3.Significant improvement in high temperature resistance: Thermal fatigue and high load are much higher than those of the original factory

4.Reduce shaking sensation：Using CNC molds to manufacture grooves to ensure the balance of the brake disc, better solve the problem of brake shaking, reject shaking, and improve driving comfort.

5.Carefully selecting materials: Made of reliable HT250 cast iron with high carbon content, it has good thermal conductivity and long service life

The function of brake drum

The brake drum is the core component of drum brakes, mainly used to generate braking force through friction with brake shoes, achieve vehicle deceleration or parking, and also have functions such as heat dissipation and enhanced friction performance.  ‌
 

Detailed functional analysis

Core braking function
 

When the driver steps on the brake pedal, the hydraulic system pushes the brake shoes to expand outward, tightly contacting the inner wall of the rotating brake drum, and using friction to slow down or stop the wheels.  ‌
 

The lever principle of drum brakes can automatically increase torque, especially in heavy vehicles such as trucks, providing stronger braking force.  ‌
 

Heat dissipation and thermal management

Brake drums need to have certain heat resistance and heat dissipation capabilities, but compared to disc brakes, their sealing structure results in lower heat dissipation efficiency and is prone to thermal attenuation (decreased braking force during frequent braking).  ‌
 

The material is usually cast iron (such as HT200-300) to balance strength and heat capacity.  ‌
 

Structural advantages and cost-effectiveness

The diameter of the brake drum is small, suitable for vehicles with limited wheel space (such as heavy-duty trucks), and the production cost is low, suitable for economical models with low requirements for braking performance.  ‌
 

The sealing design can prevent sediment intrusion and extend the lifespan of components, but it is necessary to regularly check for wear and tear.  ‌
 

Summary: Brake drums have shown outstanding performance in braking efficiency, cost control, and adaptability to specific scenarios, but their heat dissipation performance is their main weakness
