ABSTRACT:
A boot-type seal having a seal and a valve. The seal has a first seal member, which is configured to sealingly engage a first surface, and a second seal member, which is configured to sealingly engage a second surface. The valve is coupled to the seal and is operable in a first condition, which inhibits fluid communication therethrough, and a second condition, which permits fluid communication therethrough. The condition of the valve changes from the first condition to the second condition in response to a fluid pressure exerted on a side of the seal that exceeds a predetermined threshold pressure. A brake assembly that incorporates the boot-type seal is also provided.
