when does anti lock brakes start to work
Anti-lock braking system Typically ABS includes a central electronic control unit (ECU), four wheel speed sensors, and at least two hydraulic valves within the brake hydraulics. The ECU constantly monitors the rotational speed of each wheel; if it detects a wheel rotating significantly slower than the others, a condition indicative of impending wheel lock, it actuates the valves to reduce hydraulic pressure to the brake at the affected wheel, thus reducing the braking force on that wheel; the wheel then turns faster. Conversely, if the ECU detects a wheel turning significantly faster than the others, brake hydraulic pressure to the wheel is increased so the braking force is reapplied, slowing down the wheel. This process is repeated continuously and can be detected by the driver via brake pedal pulsation. Some anti-lock systems can apply or release braking pressure 15 times per second.[23] Because of this, the wheels of cars equipped with ABS are practically impossible to lock even during panic braking in extreme conditions.
Breaking Bad (season 1) The first season of the American television drama series Breaking Bad premiered on January 20, 2008 and concluded on March 9, 2008. It consisted of seven episodes, each running approximately 48 minutes in length, except the pilot episode which runs approximately 58 minutes. AMC broadcast the first season on Sundays at 10:00 pm in the United States. Season one was to consist of nine episodes, but was reduced to seven by the writer's strike. The complete first season was released on Region 1 DVD on February 24, 2009[1] and Region A Blu-ray on March 16, 2010.[2]
