Types of Backing Plates

Backing plates are essential components of disc brakes, providing a solid foundation for the brake pads and ensuring efficient braking performance. They come in various types, each with its unique materials and construction, influencing the overall performance and durability of the brake system.

The most common types of backing plates include:

Steel Backing Plates

Steel backing plates are the most widely used type, offering a robust and cost-effective solution. They are typically made from high-strength steel, providing excellent durability and heat resistance. Steel backing plates are known for their ability to withstand high temperatures and pressures, making them suitable for demanding applications.

Aluminum Backing Plates

Aluminum backing plates are lightweight and corrosion-resistant, making them a popular choice for high-performance vehicles. They offer good heat dissipation, reducing the risk of brake fade during intense braking. However, aluminum backing plates may not be as durable as steel backing plates and can be more expensive.

Composite Backing Plates, Locates shoes on the backing plate

Composite backing plates combine the advantages of both steel and aluminum. They feature a steel core for strength and durability, with an aluminum surface for weight reduction and corrosion resistance. Composite backing plates offer a balance of performance and cost, making them suitable for a wide range of applications.

Ceramic Backing Plates

Ceramic backing plates are the most expensive type, but they offer exceptional heat resistance and durability. They are made from a ceramic material that can withstand extremely high temperatures, reducing the risk of brake fade and improving braking performance in demanding conditions.

Materials for Locating Shoes

When selecting materials for locating shoes on the backing plate, several factors must be considered, including the required accuracy, durability, and cost. The most commonly used materials include:

Metals

• Steel:Steel is a strong and durable material that is often used for locating shoes in high-precision applications. It is resistant to wear and tear and can withstand high loads.
• Aluminum:Aluminum is a lightweight and corrosion-resistant material that is often used in applications where weight is a concern. It is not as strong as steel, but it is more affordable.
• Brass:Brass is a corrosion-resistant material that is often used in marine applications. It is more expensive than steel or aluminum, but it is more resistant to saltwater corrosion.

Plastics

• Nylon:Nylon is a strong and durable plastic that is often used for locating shoes in low-precision applications. It is lightweight and inexpensive, but it is not as strong as steel or aluminum.
• Polyethylene:Polyethylene is a lightweight and flexible plastic that is often used for locating shoes in applications where flexibility is important. It is not as strong as nylon, but it is more resistant to chemicals.
• Polypropylene:Polypropylene is a strong and durable plastic that is often used for locating shoes in applications where high strength is required. It is more expensive than nylon or polyethylene, but it is more resistant to wear and tear.

Equipment for Locating Shoes

Locating shoes on a backing plate requires specialized equipment to ensure accuracy and efficiency. These tools are essential for achieving precise placement and alignment of the shoes during the manufacturing process.

The essential equipment for locating shoes on a backing plate includes:

Shoe Locating Fixture

• Description:A precision-machined device that holds the shoes in place and guides their placement on the backing plate.
• Function:Ensures accurate alignment and spacing of the shoes, preventing errors during assembly.

Dial Indicator

• Description:A precision measuring instrument that measures minute displacements and variations in position.
• Function:Used to verify the exact position of the shoes relative to the backing plate, ensuring they are perfectly aligned.

Precision Measuring Tape

• Description:A flexible, calibrated tape measure used for accurate distance measurements.
• Function:Measures the distance between the shoes and the backing plate, ensuring proper spacing and alignment.

T-Square or Combination Square

• Description:A precision tool used for drawing and checking right angles and straight lines.
• Function:Ensures that the shoes are perpendicular to the backing plate and aligned correctly.

Center Punch
