What about productivity and the cost of operation?
Discs and pads are much quicker to replace than drums and shoes. But this is not where the real savings accrue. Scania EBS (Electronic Brake System) is an intelligent system that is able to apportion precisely the right amount of braking force to each
wheel. This results in even wear on all brakes at each wheel. When the front axle pads need replacement, so too will the rear. That means one visit to the workshop instead of two.
