Pontiac G6 Brake Disc

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.

  • Three Easy Techniques to Maintain your Pontiac G6 Brake Disc 27 February 2013

    No matter how hard you try to keep your Pontiac G6's brake disc from wearing out, eventually, it will succumb to corrosion. Little by little, rust would eat it up, and you have no choice but to replace it. A corroded brake disc would only harm the entire brake assembly, if you choose to keep it. Before this happens, you should maximize your brake disc and do what you can to prevent it from rust. Here are some maintenance tips that might help you make the most out of your stock or replacement brake disc:


    Clean it regularly.

    Keeping your car components clean is the easiest way to prolong its service life. Since corrosion could be caused by dirt and moisture, a clean brake disc becomes less prone to rust. To do this, you can use an isopropyl alcohol or a brake cleaner to remove the dirt stuck on the disc. You can also brush the non-padded area using a wire wool and wipe off the residue using an alcohol or brake cleaner. You can also get rid of the rust spots by scratching them off with the wire wool.


    Inspect the disc's surface and thickness.

    If, upon visual inspection, you see that the disc's thickness has thinned to about 1mm, or if the disc has cracks that are longer than 30mm or dark patches or grooves on its surface, then it is about time to replace it. These are the most common signs that the brake disc should be replaced. And if you replace the discs, make sure that you also replace the pads. This is to ensure that both will have an equal service life, or that one will not wear out ahead of the other.


    Bed in your new brakes.

    After replacing your stock brake disc and pad, you notice that there seems to be no change on your vehicle in terms of performance. The new set of brakes needs to undergo a bedding period, wherein it is tested by driving 300 to 400 miles while using the brakes lightly. The new disc and pad need to go through a stage to remove the misalignment of the pads against the rotor. This way, the disc will be perfectly in contact with the pad, which could lead to improved performance and durability.
