@josephmartinengineer: Slam the brakes in any modern car and the pedal shakes, buzzes and kicks back at your foot. Nothing's broken: that's ABS, the anti-lock braking system. A toothed ring and a sensor at each wheel tell a computer exactly how fast every wheel is turning. The moment one wheel slows down faster than the car, it's about to lock, so a valve in the ABS unit holds the brake pressure, another valve lets fluid out, the wheel spins back up and the pressure comes right back. Up to 40 times a second, on every wheel. A rolling tire grips better than a sliding one, so you stop hard and you can still steer. The fluid that was let out gets pumped back up the line toward the pedal, and that's the kick you feel. Without ABS, locked front wheels slide straight ahead no matter how you turn the wheel. So don't pump the brakes and don't ease off: stomp, stay, steer. ⚠️ Did you know your brake pedal is supposed to do that? Tell me in the comments 👇 Sources: • Bosch Mobility, "Antilock braking system": ABS reduces and reapplies brake pressure up to 40 times a second; wheel-speed sensor at each wheel; hydraulic unit with valves, return pump and control unit; the pedal may pulsate. • NHTSA, DOT HS 811 182 (2009), "The Long-Term Effect of ABS in Passenger Cars": locked front wheels can't steer; "Do not pump the brake pedal in cars equipped with ABS… Stomp, stay, and steer"; FMVSS No. 126 (electronic stability control, all new light vehicles from the 2012 model year) de facto puts ABS on every new car. • Mazda USA, "What is ABS": don't pump ABS brakes; apply firm, continuous pressure and steer. #ABS #brakes #carsafety #engineering #shorts

Junkyard Garage :

my brakes shake like that and I have no abs

jotamkhemai :

wrong shaky pedal means brake disc or brake drums ar not calibrated means it's worn out, you have to change the drums/disc ABS doesn't let you feel what you are telling in the video

Jeorge :

scariest thing you will experience when driving is when you brake and the pedal starts to fight you 😭

Kairos Afthátheia :

I have a car that never breaks and has abs

Brayden :

You ultimately stop slower tho on dry roads

DarthFuzzyDeGenX :

3 not 4. rear brakes are on the same line whereas the front brakes are seperate.

Jen :

here and I was worried something was wrong with my brakes in my newer car. my previous car didn't have ABS, it was a 97 accord LX 😂
