Below is a list of Brake Lining manufacturers from Philadelphia, Pennsylvania. Brake lining is a friction causing material which is used in braking mechanism systems in order to aid in the slowing or stopping of motion. Machinery and almost all types of vehicles use brake linings of one sort or another. They are often also called brake pads, and are a critical component of braking systems as they are the material which comes into contact with the rotors in order to slow them down without wearing them out too quickly.
