In the braking system of heavy-duty trucks, the selection of brake shoes directly affects safety, performance, and maintenance costs. Among numerous available products, brake shoes 4707 have attracted much attention in the commercial vehicle sector. This article will delve into two core questions: Are brake shoes 4707 of the low-dust type? And are they suitable for trucks? We will provide a comprehensive analysis based on the rich experience of professional auto parts manufacturers in the production of brake components.
Reliable Background of High-Quality Brake Components
Before in-depth research on the characteristics of brake shoes 4707, it is necessary to understand the professional capabilities of professional brake component manufacturers. Such manufacturers were established in 2015 and are located in Shijiazhuang City, Hebei Province. They focus on the R&D, production, sales, and service of various auto parts for cars and trucks, covering products such as brake pads, brake discs, brake shoes, fuel pumps, and truck air dryers.
With a factory area of 5,000 square meters and more than 50 experienced employees, these manufacturers strictly adhere to quality control standards. They also have professional laboratories to support product R&D and technological innovation, ensuring that products meet or exceed industry requirements. Their products are not only popular in various provinces and cities across China but also exported to countries and regions such as Germany, Italy, Spain, Turkey, and South American countries. Meanwhile, they provide OEM and ODM services, capable of customizing solutions according to the specific needs of global customers. Their profound accumulation in the field of brake component manufacturing makes them a reliable reference for interpreting the characteristics of brake shoes 4707.
Are Brake Shoes 4707 Low-Dust?
Low-dust performance is one of the key indicators of brake components. Excessive dust not only accumulates on wheels and affects the vehicle's appearance but also may cause environmental issues. To determine whether brake shoes 4707 are low-dust, we need to start with their material composition and design features, which are the core factors determining the amount of dust generated.
From the material perspective, high-quality brake shoes 4707 usually adopt a semi-metallic friction material mixture. This mixture generally contains approximately 60% steel fibers, 30% ceramic particles, and a special resin infused with graphite. The addition of ceramic particles plays a crucial role in reducing dust. Ceramic materials have a smooth texture and stable friction performance, which can minimize the wear of the friction material during braking. Different from traditional organic brake shoes that may produce a large amount of dust due to the decomposition of organic fibers, the semi-metallic and ceramic combination used in brake shoes 4707 can reduce the amount of debris generated in each braking cycle.
In terms of design, advanced brake shoes 4707 incorporate embedded cooling channels—namely, micro-groove structures on the friction surface. These channels not only can increase heat dissipation efficiency by 22% during repeated braking but also help divert the generated dust. Instead of allowing dust to accumulate between the brake shoe and the brake drum, the micro-grooves guide the dust outward, thereby further reducing the overall dust emission. Manufacturers that focus on technological innovation will deliberately adopt such designs when developing brake shoes 4707 to align with the production concept of low-dust and high-performance brake components.
Practical usage feedback also confirms the low-dust characteristic of brake shoes 4707. Customers who have used this type of brake shoe in heavy-duty application scenarios such as garbage trucks and engineering vehicles indicate that compared with standard brake shoes, the amount of dust accumulated on the wheels is significantly reduced. This is particularly important for fleet operators, as it can not only keep the vehicle's appearance clean but also reduce the frequency of wheel cleaning, saving time and labor costs.
Are Brake Shoes 4707 Suitable for Trucks?
Trucks, especially medium and heavy-duty trucks (Class 6 to 7), have special requirements for braking systems. The brake components they need must be able to withstand high temperatures, heavy loads, and frequent braking cycles while ensuring stable braking force. Brake shoes 4707 are designed specifically to meet these needs, making them highly suitable for trucks. The specific reasons are as follows:
1. Optimized Dimensions for Truck Drum Brake Systems
The core dimensions of brake shoes 4707 are carefully designed to fit the drum brake systems commonly used in Class 6 to 7 trucks. Their arc length is approximately 14.3 inches (363 millimeters), and they are matched with a steel backing plate with a thickness of about 0.39 inches (10 millimeters). These dimensions are not set arbitrarily but are intended to maximize the contact area between the brake shoe and the brake drum. A larger contact area enables the even distribution of braking force, reducing pressure on a single point and avoiding premature wear.
In addition, the radius of curvature of brake shoes 4707 is 114°, which perfectly matches the standard 16.5-inch × 7-inch brake drums equipped on many trucks. This precise fit ensures full circumferential contact within a tolerance of 0.020 inches (0.5 millimeters), guaranteeing stable braking performance every time the brakes are applied. Strict quality control processes ensure that each brake shoe 4707 meets these dimensional standards, allowing it to fit a variety of truck models.
2. Excellent Heat Resistance and Fade Resistance
Trucks often operate in harsh environments, such as long downhill sections or frequent braking in urban traffic, which can cause a significant increase in brake temperature. Brake fade— a decrease in braking efficiency due to high temperatures— is a major safety hazard for truck operators. However, brake shoes 4707 effectively address this issue with their excellent heat resistance and fade resistance.
The friction material of brake shoes 4707 can maintain a stable friction coefficient of 0.38 to 0.42 within different temperature ranges, ensuring stable braking performance even in high-temperature environments. Test data shows that at a temperature of 650°F (343°C), this type of brake shoe can still maintain 92% of its initial friction force, far exceeding the industry average of 78%. This means that even after multiple heavy braking operations, brake shoes 4707 will not lose their braking force, providing reliable safety guarantees for trucks.
Professional laboratories play a key role in verifying the heat resistance of brake shoes 4707. These laboratories conduct strict thermal analysis using computational fluid dynamics to simulate real braking scenarios. Test results show that brake shoes 4707 with nickel-reinforced edges reduce the generation of hot spots by approximately 18% compared with standard designs during ten consecutive braking operations from 60 mph to 0. This thermal stability not only prevents brake fade but also extends the service life of brake shoes and related brake drum components.
3. Durable Structure for Heavy Loads
The heavy cargo carried by trucks exerts enormous pressure on the braking system. Brake shoes 4707 can withstand this heavy-load test with their durable structural design. The steel backing plate provides strong support to prevent deformation under high pressure. In addition, the wear rate of the semi-metallic friction material is extremely low, with only 0.0015 inches of wear per 1,000 braking cycles, which is 40% lower than that of standard organic linings. This means that brake shoes 4707 have a longer service life, which can reduce the replacement frequency for truck fleet operators and lower maintenance costs.
In controlled laboratory tests, even after 15,000 cycles of braking under a heavy axle load of 12,000 pounds, the lining compression of brake shoes 4707 is only 0.002 inches (0.05 millimeters). This durability is crucial for trucks operating in harsh environments such as construction sites and waste disposal areas, where the braking system is continuously subjected to high pressure. Professional production lines ensure that each brake shoe 4707 meets such durability standards through strict manufacturing process management, using high-quality materials and advanced production technologies.
4. Compatibility with Aging Truck Systems
Many truck braking systems currently on the road have aged, and the diameter of the brake drum may deviate due to wear. Brake shoes 4707 have taken this situation into full consideration in their design and have good compatibility, making them suitable for both new and old trucks. They adopt a spring-loaded pivot design, which can adapt to brake drum diameter deviations of 0.15 to 0.35 inches (3.8 to 8.9 millimeters). This design eliminates the need for manual adjustment, reduces maintenance downtime, and always ensures the optimal clearance between the brake shoe and the brake drum.
For truck operators with old fleets, this compatibility is a significant advantage. They do not need to replace the entire brake drum assembly; instead, they only need to upgrade to brake shoes 4707 to improve the performance of the braking system, saving time and costs. Professional customer service teams also provide support at any time, offering guidance based on specific needs to help integrate brake shoes 4707 into existing truck systems, further enhancing their applicability.
