I don’t remember the older mu cars mp54, mp72 and 75 cars having an issue with leaves on the track and sliding. Are the new mu cars sliding because of the quick braking they have compared to the older mu’s?
first problem is different brake shoes the composite shoes polish the wheels and generate more heat.
second problem is ABS system as it released brakes on wheels that even marginally slip .
third problem is Dynamic brake, no real brake shoe action till almost below 10 mph.
on older cars there was no dynamic brake, the brake shoes were cast iron, plus twice as many and they actually roughened the surface.
