  • Patent number: 6568513
    Abstract: An adjustment arrangement for a non-servo drum brake having a hydraulic actuator that engages a first web of a first brake shoe and a second web of a second brake shoe. The hydraulic actuator on receiving a hydraulic input develops an actuation force for moving the first and second brake shoes from a rest position into engagement with a rotatable member to effect a brake application. An extendible member, that is connected to the first web and the second web, is extendable to define a running clearance in a rest position between the first and second brake shoes and the rotatable member. A lever arm, that is mounted on the first web, engages the extendable member. A resilient member extends between the lever to the second web to urge the first and second webs into engagement with the hydraulic actuator. The lever arm pivots on the first web as the first web moves through the running clearance during a brake application.
