Brake shoes are an essential component of drum brake systems, which are commonly found in older vehicles. They work by pressing against the brake drum, which slows down the rotation of the wheel. There are various types and sizes of brake shoes available in the market, and it is essential to know the differences between them before making a purchase. In this article, we will compare the 4707 and 4515 brake shoes, highlighting their differences in terms of specifications and performance.
Specifications Table:
| Specification | 4707 Brake Shoes | 4515 Brake Shoes |
|---|---|---|
| Dimensions (Length x Width x Height) | 7.17″ x 2″ x 1.875″ | 7.17″ x 1.75″ x 1.875″ |
| Friction Material | Organic | Ceramic |
| Number of Rivets | 4 | 4 |
| Application | Heavy-Duty Trucks and Trailers | Light-Duty Trucks and Passenger Cars |
| Wear Sensor | No | Yes |
Differences between 4707 and 4515 Brake Shoes:
- Dimensions: The most significant difference between the 4707 and 4515 brake shoes is their size. The 4707 brake shoes are slightly wider than the 4515, with dimensions of 7.17″ x 2″ x 1.875″. On the other hand, the 4515 brake shoes have dimensions of 7.17″ x 1.75″ x 1.875″. The size difference is mainly due to the type of vehicles they are designed for.
- Friction Material: Another significant difference between the two brake shoes is the type of friction material used. The 4707 brake shoes use organic friction material, which is made of a blend of fibers and resins. On the other hand, the 4515 brake shoes use ceramic friction material, which is made of a combination of ceramic fibers and non-ferrous metal.
- Application: The 4707 brake shoes are designed for heavy-duty trucks and trailers, while the 4515 brake shoes are designed for light-duty trucks and passenger cars. The difference in application is due to the size and weight of the vehicles they are designed for.
- Wear Sensor: The 4515 brake shoes come with a wear sensor, which alerts the driver when the brake pads are wearing out. The 4707 brake shoes do not come with a wear sensor.
Conclusion:
In summary, the 4707 and 4515 brake shoes differ in terms of size, friction material, application, and the presence of a wear sensor. It is essential to consider these differences when selecting the appropriate brake shoes for a specific vehicle. The 4707 brake shoes are ideal for heavy-duty trucks and trailers, while the 4515 brake shoes are ideal for light-duty trucks and passenger cars. Ultimately, choosing the right brake shoes can improve the vehicle’s braking performance and ensure safe driving.
