In a car without ABS the front wheels are more likely to lock and the car can’t be steered, no matter how far you turn the steering wheel.

However, ABS allows a driver to maintain control of the direction the car is heading in, and therefore steer away from an obstacle. In fact in some circumstances, ABS can increase a car’s braking distance, because the brakes aren’t being applied consistently. However, one common misconception is that braking distances are shorter with ABS. ABS works on wheels fitted with brake discs, so on cars with four discs it can work on all four wheels. You may also be able to hear the brakes ‘chattering’ loudly while ABS is working.

You can feel the effect through the brake pedal in the form of rapid pulsing.

Canada: View a printable PDF on understanding your vehicle’s ABS.A vehicle's ABS (anti-lock braking system), which is also known as the anti-lock brakes, stops the wheels from skidding when the brakes are applied hard, and allows the driver to steer around an obstacle at the same time.ĪBS uses sensors to detect when a wheel is about to start skidding, and employs hydraulic valves to ease the brake pads from the discs before reapplying them repeatedly.United States: View a printable PDF on understanding your vehicle’s ABS.Check our field references to see if your vehicle requires a functioning anti-lock brake system (ABS). If ABS lamps illuminate and stay on, you also have a violation. If ABS lamps do not illuminate at all, you likely have a violation. If your vehicle or combination includes any units that were required to be anti-lock brake system (ABS) equipped at the time of manufacture, those unit(s) must have a functioning ABS malfunction lamp(s) that turns on and then off when power is supplied to the unit. Remember, if the lamp does not work, the driver will never know if the ABS stops working. Make sure any problems found are fixed as quickly as possible. If the light stays on during the self-test or comes on as the vehicle is being driven, there is an ABS malfunction. If the lamp does not come on during the self-test, there could be a problem with the lamp bulb, the wiring or the ABS controller. When an ABS malfunction is detected during this test, the lamp stays on otherwise, the lamp turns off after a few seconds. During this time a self-test of the ABS is automatically conducted. When power is supplied to the trailer ABS unit, by the ignition switch being turned on (for ABS required power units) or by applying the brake pedal (for non-ABS required units), the lamp on the trailer momentarily turns on to indicate the ABS is working. If the vehicle you drive was built after March 1, 2001, and it is equipped to tow a trailer, it will actually have two ABS lamps on the dash – one for the tractor (or truck) and one for the vehicles being towed. Converter dollies also have the lamp located on their left side. A yellow colored lamp, marked with the letters “ABS,” is located on the instrument panel of trucks, buses and truck tractors (dash-mounted), and located on the exterior of trailers, near the red side marker lamp on the left rear side (trailer-mounted).

Know where the ABS lamp is on every vehicle you operate and how to check that it’s working properly. It may repeat this sequence several times a second and it may control each wheel differently. ABS deploys the airbags during a collision. When the brakes are applied, the ABS senses when a wheel is about to lock and then releases just enough brake force to get the wheel rolling again while still maintaining as much braking force on the wheel as possible. What does Anti-lock braking system (ABS) do ABS prevents the wheels from locking under harsh braking conditions.
