A brake lining includes a mounting plate, sliding members and elastic members. The sliding members are arranged in the transverse direction and the longitudinal direction of the mounting plate on one surface of the mounting plate to form transverse rows and longitudinal rows. The elastic members are provided in correspondence with the sliding members. Each of the elastic members is disposed between the corresponding sliding member and the mounting plate. A gap exists between adjacent transverse rows, and extends over the entire length of the transverse rows. A gap exists between adjacent longitudinal rows, and extends over the entire length of the longitudinal rows. The gap has a width that is smaller than a width of the gap.

A method of making a wet friction material includes joining filler particles and fibers together and forming a base; coating an outer surface of the base with a quaternary ammonium salt containing solution; and drying the quaternary ammonium salt containing solution to form a quaternary ammonium salt containing coating on the outer surface of the base.

A brake shoe includes a backing plate configured to interface with a brake head of a vehicle. The backing plate includes a main body and a flange attached to the main body and configured to align the brake shoe on a wheel of the vehicle. The brake shoe also includes a composition friction material disposed on the backing plate, which defines a brake surface for engaging the wheel. The brake shoe may have one or more dimensional characteristics for facilitating alignment of the brake shoe with the wheel, e.g., a ratio of a shortest horizontal distance to a shortest vertical distance of the brake shoe may be at least 1.07 and no more than 1.25, or a ratio of a length of the main body of the brake shoe to a length of the flange may be at least 1.3 and not more than 1.7.
