Is this Europe?xXCARL1992Xx wrote: ↑31 Mar 2022 18:02 every truck and trailer has ABS (well it is called EBS and it is mandatory on ever truck+trailer) and it works 100% of the time, if it doesnt it means it is defective or the sensors are broken, its job is exactly to prevent the locking up of the wheels (the EBS version is even so advanced it locks/unlocks the brakes depending on the wheel many times a second) also all our newer trucks and trailers (at least the last 10 to 15 years maybe more) are equipped with disk brakes, there is no drum brake not even as option for all i know, this can also be a big factor, also, the weight of the vehicle is irrelevant for the ABS, it just checks if the wheel is rotating or not, if not, release brakes to get it rotating again
In the US, trucks have drum brakes, and the Emergency Braking System (EPS) is different from the Anti-lock Brake System (ABS). EBS utilizes ABS, but they are not the same thing.
And yes, ABS does not care about the Wright of the vehicle. However, the brakes themselves are effected by the vehicle's weight, and the weight can determine how prone they are to locking up.
