摘要：A brake system for braking a rotatable brake disk (14, 16) includes a primarybrake piston (26, 28) engagable with the brake disk (14, 16) and a secondary brake piston(34, 36) engagable with the primary brake piston (26 ,28) and operable to move theprimary brake piston (26, 28) into engagement with the brake disk (14, 16). Both pistons(26, 28, 34, 36) are operable in response to fluid pressure. A primary brake valve (54)controls communication of fluid pressure to the primary brake piston (26, 28). Asecondary brake valve (62) controls communication of fluid pressure to the secondarybrake piston (34, 36).
