What Material Are Brake Shoe Linings Made Of?
1 Answers
Brake shoe lining materials mainly include asbestos resin friction materials, asbestos-free resin friction materials, metal fiber reinforced friction materials, semi-metal fiber reinforced friction materials, and hybrid fiber reinforced friction materials. Brake shoe linings refer to the components that are pushed outward by the brake cam or push rod to press against the brake drum for braking. When the brake shoe friction linings are severely worn, or the surface of the friction linings is heavily contaminated with oil or burnt, new linings should be replaced. During replacement, both wheels must be replaced simultaneously, and friction linings from the same manufacturer, with the same brand and similar materials must be selected. If the new linings do not fit well with the brake drum, they should be ground until the required fit is achieved.
