Here at Mechanic Guides we wanted to review the best rotors for GMC Sierra.
Quick intro to rotors. Automotive rotors are the “disc” part of brake pad kits. These are precision machined discs of high-grade metal that are designed to hold the brake pads.

There is not much more to write up about them, the difference in metal and design is what separates the model’s performance. To make things easier for you to decide which ones are the best for your vehicle, I present to you a guide of the top 4 best rotors for GMC Sierra.
Take note that the Power Stop parts review is virtually identical, the difference is in the application and dimensions, everything else in these kits is the same.
Best Rotors for GMC Sierra Reviews:
1. Power Stop AR8640XPR Front Evolution Drilled & Slotted Rotor Pair
The Power Stop® AR8640XPR Evolution Performance Drilled and Slotted Vented 1-Piece Front Brake brings you all the advantages of a ceramic pad with cross drilled rotors. These brake pads are designed for performance and racing applications only.
Power stop is a precision engineering company, and they use their proprietary Tru-Cast™ technology method that delivers rotor run outs of 0.0015± tolerance and DTV specification within 0.005± tolerance.
This model’s rounded slots sweep away dust, gas, and water to maintain a clear contact patch between the rotor and pad. The beveled drill holes provide a better heat exchange and reduce operating temperatures to the minimum.
The rotor is zinc plated for resistance to corrosion, and the pads are made of a thermally scorched carbon fiber ceramic providing an optimized braking solution. The back plate is powder coated, and the shims come with a premium rubber coating.

Conclusions
There five reasons to replace your rotor or whole disk pad kit and these include:
- Squeaking front brakes.
- The car or brake pedal is shaking when you brake.
- The car pulls to either side when braking.
- There is a grinding noise when braking.
- You want to upgrade to a better performance kit for a specific application.
The first four instances will require you either replace the entire brake kit or only part of the brake pad kit, such as resurfacing the rotor for issue number 2. or replacing the calipers in issue number 3.
You can either replace with standard stock kits or invest in an aftermarket kit that can improve performance for specific applications. This goes hand in hand with issue number 5 when you change your vehicle for a specific purpose.
Pimping up or pumping up your vehicle can include increased engine performance, as well as changing the wheel and tire sizes. You must change your brake pads to match the new performance levels.
Take heed, while good tires and shock absorbers keep your tires on the ground, a good braking system gives you control over performance and will save your life as well as pedestrians. Only invest in high-quality braking parts.
