What are truck brake shoes made of?

These brake pads are comprised of metal shavings of copper, steel, graphite, and brass bonded with resin. They are best suited for vehicles that are used for everyday driving. Heavy-duty vehicles like trucks that carry loads and need high braking power also use semi-metallic brake pads.

What are the materials used for brake linings?

The three kinds of brake lining material are non-asbestos, semi-metallic, and ceramic friction.

• Non-Asbestos Brake Lining. Non-asbestos is an organic lining that is environmentally friendly and durable.
• Semi-Metallic Brake Lining. The second lining material is semi-metallic.
• Ceramic Friction Brake Lining.

What is the difference between 4707 and 4515 brake shoes?

Until now, the 4515 brake shoe has been easily distinguishable from the 4707 brake shoe by the prominent “hump” found on the 4515 web rails, while 4707 web rails remained smooth along the arc of the web. See Figure 1. However, 4515 brake shoes without the hump have recently become common.
