Brakes have become better within 30 yrs in many ways, especially in slippery conditions. Braking was a nightmare when icy roads, there where lags and skids etc. I drive a vehicle which is 6x2 rigid + a 5-axle drawbar trailer, GVW of 60-63t/ca.138000 lbs. It has an EBS, electronically controlled brake system with discs+brake blending (motor brake and hydraulic retarder). When emergency braking as on this vid, all the pads hit at the same time and release as well, also pads and discs wear equally
Since the mid 1990s, all heavy trucks are equipped with Antilock Braking Systems (ABS) which prevent brake lock-up or skidding under any load or road condition.
Both vehicles are comparably equipped and are tested per the Federal Motor Vehicle Safety Standard (FMVSS) vehicle test procedure. This includes properly burnished (worn in) brakes along with an unbraked trailer carrying 4,500 lbs. The purpose of the video is to compare the performance of two comparable tractors and to give a true indication of how both would perform to the FMVSS.
Well what the hell, why doesn't this video compare the gross weight of each truck or say anything about tires? It's hard to see if either of them has a load on. I don't know what it would be other than flat sheets of steel. The trailers look empty. If that's the case something's wrong because an empty truck with new brakes properly adjusted is going to skid in a sudden stop. The driver is the variable in this test. These trucks should be "overloaded" -- 90,000 lbs to prevent skidding.
@peanuts2105 Keep in mind that at a steep decent a SMART trucker would use his engine "retarder" brake instead of using the foot brake all the way down and melting his brakes.
muy bien que pena que a mexico tarde mucho para llegar esta tecnologia

It just seems crazy that huge heavy trucks like these are fitted with drum brakes. I wouldn't even have drums on my car let alone a truck.
Imagine steep decent with drum brake fade...I rather not
I gather the ADB system are vented discs.
Good vid
