The cost I have found for a set of rotors, drilled and slotted plus ceramic pads is around $250. Seems cheap compared to the possible loss of braking power. We have had people jump in front of our rig while trying to give distance to the cars in front while coming down a steep grade. When your brakes are already shimmering it makes it tough to feel like you have anything left to stop. I know how to use the tranny and how to brake hard and then back off. Been driving buses and trucks so that is not the issue. The way people are and the equipment seems marginal since when they place a large rv chassis on a Van chassis it makes all those great brakes that are stock somewhat questionable. Most of the braking is done with the fronts so that is where I intend to spend for the upgrade. Not sure how to check for the correct valve or system...but changing the fluid is also on the list. I always have it power flushed.
