FAQs— GMC Brake Disc and Pad Kit
- After installing a new GMC brake disc and pad kit, will I immediately notice improvement in my ride’s braking power?
No, you won’t. In fact, the first few applications of your new brakes will yield very little added braking power. For you to build up some grip, you first need to gently apply the brakes for several times at low speed before you drive down the road at normal to high speed. The process of building your grip is called bedding in, and it is done to allow your newly installed brakes to work as well as they are designed to. Bedding in is recommended for those who have installed a new brake kit or new pads and rotors, as well as for those who have purchased a new car.
- Every time I drive my GMC down the mountain pass during our weekend getaways, I notice that my brakes get hot but I just ignore it and continue to drive. What can I do next time to prevent this from happening?
The usual remedy for such is to pull over and wait for a few minutes until your brakes cool down. As the components of your brakes cool down, they regain their ability to take in heat. So as you drive again, the brakes will seem to work just fine.
- After completing the required break-in cycle for my new GMC brakes, I noticed a light blue tint on the face of the rotor. Is that normal?
That is but normal, and that’s actually what you should look for on each face of your rotor after the break-in cycle. The slight blue tint indicates that your new brake disc or rotor has reached the necessary break-in temperature.
- I also noticed a sort of light gray film on the rotor surface. What does that mean? Is that something I should worry about?
It’s a good thing if you notice a light gray film on the face of each rotor because that means your new brakes have already reached their full potential. That gray film is actually a brake pad material that’s being transferred onto the rotor surface. If the layer of pad material deposited on the rotor’s face is even, you should give yourself a pat on the back for doing the break-in properly.
- My GMC brake rotors are now slightly warped. I read online that the rotors can be turned so as not to compromise the braking performance. What does “turning” the rotors mean?
“Turning” the brake rotors means “resurfacing” or “machining” them to get rid of uneven wear and warping, thus giving the rotors a smooth braking surface. When turning the rotors, they are usually placed on a lathe, where a small amount of the disc surface is shaved off to make their face smooth again.
- When should I have my GMC brake rotors turned?
It would be wise if you can have the rotors or brake disc of your GMC turned at every brake service or every time you replace your brake pads. By doing so, you are giving your new brake pads a smooth braking surface, therefore helping ensure better pad wear. This will also give you improved braking performance without the need to shell out bucks for new rotors. However, turning the rotors frequently shortens their lifespan. Thinning of the rotors could also mean losing some of their heat dissipation ability, and thus making them prone to brake fade.
- My GMC brakes produce squeaking sound every time I step on the brake pedal. Does this mean I will need a new GMC brake disc and pad kit soon?
Such brake noise is a sign of a brake problem, but you need to do some troubleshooting first before you decide to purchase a new brake kit. This squeaking sound can be caused by the pads that have hardened or glazed due to humidity. The friction surface of “glazed” pads generates noise as it comes in contact with the brake disc. That unusual sound when braking can also be the first sign of a weak link in the brake system, which, when left ignored, can lead to brake failure. If your GMC brakes consistently produce such sound when the brake pedal is stepped on, have your brakes checked and serviced as soon as possible.
Benefits to Gain from Installing the Right GMC Brake Disc and Pad Kit
Brake disc and pad kits are provided by both OEM and aftermarket manufacturers. Since most manufacturers offer complete brake disc and pad kits that are already complete with the necessary components, this can significantly help you save some time, money, and effort in sourcing for the individual parts needed for replacing your rotors and pads. However, you may want to check for the available kits in the internet first to make sure the one you'll get will match perfectly with your preference as well as your vehicle make, model, and year. Other than helping you save some bucks and time, you can gain other benefits from getting a GMC brake disc and pad kit.
Give better stopping ability
Getting a good-quality brake disc and pad kit for your GMC is important for optimal braking performance. Some discs and pads such as the dimpled brake discs and semi-metallic brake pads provide great stopping capability. Great for racing vehicles, the dimpled brake discs deliver great response during sudden braking situations. Because of their dimples, stress on the discs is minimized, extending the service life of the brakes. Much like with the dimpled discs, semi-metallic brake pads also improve your stopping ability. Although they produce more noise compared to other types of brake pads, semi-metallic pads are more suitable for track use. Moreover, there are performance brake kits you may want to consider for superior stopping performance on racetracks. These kits are usually used for high-speed applications.
Reduce brake fade
Some GMC brake disc and pad kits, such as the performance and semi-metallic brake pads, are especially designed to expel heat faster. Both of these pads are engineered to reduce heat, thus minimizing the occurrence of brake fade. Due to their metallic composition, semi-metallic pads keep heat away from the disc and help cool the brakes. These pads have higher thermal threshold and maintain more consistent friction properties. In addition, slotted brake discs and vented discs also minimize brake fade by letting cool air through their slots and into the discs. Vented discs are especially suited for driving in traffic areas, where you have to frequently stop. Take note that each brake pad in any brake system is engineered to function at specified operating temperatures. And because it is made of different formulations, each pad works in different ways under various temperatures.
Produce minimal noise and less brake dust
OEM and aftermarket brake kits include rotors and pads that produce less noise like the ceramic pads, organic pads, and slotted discs. Recommended for daily driving, ceramic pads are commonly fitted on many passenger vehicles since they do not make much noise and produce less brake dust. They also work well even on high temperatures, ensuring good braking performance even after long drives, when the vehicle usually suffers from brake heat. Additionally, ceramic brake pads cause minimal wear on your discs because of their dense ceramic composition. As for the brake discs, the slotted and drilled ones usually work better than stock rotors because the slots or holes ensure better air ventilation and heat faster.
