Brake Valve Plunger
Bendix

Inside a brake valve, the plunger translates actuator movement into precise valve travel, forming a crucial part of the modulation system that manages reservoir pressure and braking force. The component’s travel characteristics, surface finish, and fit determine response time and stability under dynamic road conditions, making it a key factor in predictable brake performance. Proper seating, lubrication, and wear inspection are essential to avoid sticking, leakage, or erratic modulation, especially in severe operating environments where moisture and contaminants can enter the valve body. VMRS code 013-010-228 places it in the valve plunger family, with category 41351 highlighting its role in braking system actuation components. Cross references are not listed, but technicians rely on compatible replacement parts to maintain brake performance, reduce maintenance errors, and extend the service life of heavy-duty air braking systems across long-haul and vocational fleets.
