Three Simple Tips to Troubleshoot your Pontiac G6 Brake Disc
Your Pontiac G6 brake disc is designed to withstand wear and tear as much as possible. Since it is typically made from metal, it is prone to corrosion. But due to its function in the braking system, inevitably, it will wear out after a couple of years. Sometimes, its service life depends on the material it is made of, or the kind of maintenance the owner does to it. If you've replaced your brake discs and pads just recently, you might want to bear in mind these tips on how to troubleshoot your vehicle's brake discs:
Brake warning indicator light is on
This is the most obvious way to know whether something's wrong in your brake assembly. A trouble code will appear if there is something that you need to check in the brakes. You can refer to a trouble code book to know about the problem further. Do not ignore such warnings as it may indicate that you need to change a worn-out brake disc or pad urgently.
High-pitched squeaks and squeals from the brake assembly
If lately you have been hearing unusual metallic sounds from your brakes, then there could be a problem with the brake disc. Usually, when you apply the brakes and hear a high-pitched squeal, the discs could be too thin due to overheating. Especially when you step on the brakes during a slow stop, try to listen for metallic screeching sounds. This could mean that one of the brake discs have worn past their lining limits. You can also notice a slight vibration from the steering wheel aside from the squeals if one of brake disc is already worn-out.
Thinner brake pad and damaged rotor
If the brake pad of your vehicle is already one-fourth of its original thickness, then your brake discs are prone to premature wear. If the pads have worn-out up to their rivets, then they should be replaced immediately. You can also check the disc rotor for striations or grooves in its surface. Once these two parts are already damaged, chances are, the brake discs are damaged as well. You need to replace all worn-out parts to ensure that your brake assembly is in proper working order.
