Brake linings are the material attached by rivits or strong glue to the metal backing of your brake pads or shoes this material must be hard so it takes time to wear and it must have a high coefficient of friction. Pads and shoes are several differet types the most common three are organic, semimetalic, metalic and ceramic. Organic pads are made with kevlar up until 2003 organic brake linings contained asbestos organic linings are the lowest grade type of lining. Semimetalic and metalic pads contain the same materials just in diffrent amounts these types of linings contain copper brass and steel shavings making them wear harder and last longer most metalic and semimetalic linings are mid grade. Now to are final type of lining ceramic linings which contain high levels ceramic material making them the hardest wearing longest lasting type of lining the are used alot in race cars and other high performance applications. Finally all linings share the same bonding agents to form the lining into the desired size shape and thickness.
