Bus and Trucks Brake linings

Description

Buses and Trucks Brake linings are the friction materials that press against the brake drum or disc to slow or stop heavy vehicles. Because these vehicles carry large loads and operate for long hours, their brake linings are built for high heat, durability, and consistent braking

What brake linings do

• Create friction against the brake drum or disc

• Convert motion into heat to slow/stop the vehicle

• Withstand high temperatures and heavy loads

Common types

1. Drum brake linings

   • Most common on buses and heavy trucks

   • Mounted on brake shoes inside a drum

   • Strong and long-lasting for heavy-duty usehttps://sumku.co.ke/

2. Disc brake pads (linings)

   • Used on some modern buses/trucks (often front axles)

   • Better heat dissipation and consistent braking

Lining materials

• Non-Asbestos Organic (NAO): Quieter, moderate durability

• Semi-metallic: Strong braking, handles heat well

• Ceramic / Low-metal: Stable performance, less wear on drums

• Asbestos (older/obsolete): Mostly banned due to health risks

Key properties for heavy vehicles

• High coefficient of friction

• Fade resistance at high temperatures

• Low wear on drums/discshttps://sumku.co.ke/

• Resistance to cracking and glazing

Maintenance & replacement tips

• Inspect regularly for thickness and cracks

• Replace linings before they reach the wear limithttps://sumku.co.ke/

• Always match lining type to axle and duty cycle

• Bed-in new linings properly to avoid uneven wear
