When you apply imperativeness to the brake pedal, the fluid in the brake lines cause the actuator to push the brake shoes outbound against the brake drum. In disc brakes, the caliper is squeezed into the brake pads. so, it is easy to see how malfunction or failure in the brake actuator can cause some dangerous issues.

Sudden Brake Failure
The worst and eventual consequence of brake actuator bankruptcy causes a sudden failure in the brake system. Since the brake actuator is responsible for both immediate braking and the parking brake, this can occur at about any meter. Owners have reported the sudden failure at many unlike speeds, including braking to slow a fomite adenine well as designed discontinue brake. failure, while parked with the parking brake engaged, has besides been reported to result in diagnosing brake actuator failure .
