Kind Code:
A1
Abstract:
Provided is a brake lining for railroad cars, which is capable of suppressing brake squeal during braking. A brake lining (10) for railroad cars according to the present invention is used in a disc brake system of a railroad car. This brake lining (10) is provided with a substrate (40), a sintered friction material (20) and a friction material supporting mechanism (30). The friction material supporting mechanism (30) is arranged between the substrate (40) and the sintered friction material (20), and supports the sintered friction material (20) so that the sintered friction material is movable with respect to the substrate. The sintered friction material (20) has a Young's modulus of 35.0 GPa or more.
