Abstract
Method and arrangement for providing a brake member having a rear plate that carries a brake lining (14) that has at least one contact surface (16), side edges (18) and end edges (19, 20). To avoid brake squeal, the wear resistance of the brake lining (14) is varied in the longitudinal direction between the two end edges (19, 20) in such a manner that at least one of the end edge portions (19a, 20a) of the brake lining (14) has lower wear resistance than a remaining part of the brake lining (14).
Claims15
A brake member comprising:
- a rear plate bearing a brake lining (14), the brake lining (14) having at least one contact surface (16), side edges (18) and end edges (19, 20);
- the brake lining (14) having a resistance to wear that varies in a longitudinal direction between the two end edges (19, 20) so that at least one of the end edge portions (19a and/or. 20a) of the brake lining (14) has lower wear resistance than a remaining part of the brake lining (14).
A method for manufacturing a brake lining (14) intended to be borne by a rear plate (15) and that has at least one contact surface (16), side edges (18) and end edges (19, 20), the method comprises:
- configuring the brake lining (14) so that a resistance to wear varies in a longitudinal direction between the two end edges (19, 20) so that at least one of the end edge portions (19a and/or 20a) of the brake lining has lower wear resistance than a remaining part of the brake lining (14).
