ABS is an electronic braking system used in cars to improve safety and control in emergency braking situations. ABS works by constantly monitoring the speed of the wheels and adjusting the braking pressure on each wheel individually to maintain traction. If it senses that a wheel is about to lock up, ABS temporarily reduces the braking pressure on that wheel to prevent lock-up and maintain steering and vehicle control.

This was a pretty simple straightforward video but it’s something that I have never seen covered before in a video and I have been very curious about this for many years. I film 3 Different cars (Supra, E55 AMG and Tesla) in slow motion with ABS anti-lock braking system to see visually exactly how antilock brakes work on a car. Watch the video Warped:
I also think by me making this video a lot of students in school who are studying mechanics can benefit from my work here in this video. I know I really dragged on this video but I figured if I include absolutely all the information in the video this would be very helpful for schools we’re trying to explain ABS to students who are studying mechanics.

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 the wheel rotating significantly slower than the speed of the vehicle, 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.
