In part one, we talked about overheated truck brakes from towing or hauling and how slotted and drilled rotors can help. In this post, we’ll answer the question: Are slotted or drilled brake rotors worthwhile for towing?
Towing and or hauling can create some extraordinary circumstances for even the stoutest braking system. In the steep mountains of Colorado, “runaway truck ramps” are a common sight because so many trucks (big and small) experience brake failure. But are a set of drilled or slotted rotors going to make a big difference when you’re towing or hauling with your pickup?
In a word, yes. Drilled and slotted rotors are for real – they can improve braking performance in a lot of different situations. In many situations where a stock set of truck brakes would overheat and fade, after-market rotors will continue to perform. Of course, like any after-market part, there are a few trade-offs to consider.

FACT: The brakes that were installed on your truck at the factory are a compromise between cost, performance, durability, and noise. While they do an excellent job of stopping your truck (even when there’s a big load being towed behind), they are far from the best option available to you. While there are some trade-offs, buying an after-market set of brake rotors can boost your truck’s braking performance (especially while towing and hauling).
In a nut-shell, most modern trucks (or trucks with disc brakes) have two main brake components – rotors and pads. Rotors are the large, flat rotating mass that are attached to your wheel hubs. Brake pads press up against the rotors in order to generate the friction necessary to stop your vehicle. Simple enough, right?
Stock, or OEM, rotors are usually completely flat, solid, and smooth. This is the cheapest and strongest configuration for a brake rotor, but it’s certainly not the best.
