Description
World American WA102761 SR-2 type trailer spring brake valve combines spring-brake control and quick-release functions in a single body, replacing Bendix 102761/102761N and the Haldex 102761X reman in trailer air-brake systems. Designed for 4-delivery / 2-reservoir port plumbing on dual-circuit trailers, with hold-off pressure limited via the integrated relay so spring brakes cannot lock from a single reservoir failure.
