FAIL-SAFE BRAKE LINKAGE Abstract of the Disclosure The fail-safe brake linkage includes a hydraulic cylinder acting upon first levers. The first levers are rotatably mounted on a respective shaft. Also rotatably mounted to each shaft is a plurality of levers connected to brake activation rods. Each first lever is biased against a respective cylinder rod of the hydraulic cylinder. During vehicle operation, hydraulic pressure is supplied to the hydraulic cylinder to extract the cylinder rods against a respective first lever, causing each first lever to assume a position which allows normal operation of the brake connecting rods. Should the vehicle lose hydraulic pressure, the hydraulic cylinder retracts, thereby allowing the biased first levers to assume a position which results in the automatic apply- ing of the vehicle brakes.
