Tips You can Follow to Maintain Your Pontiac Grand Prix Brake Disc

Pontiac Grand Prix brake disc maintenance is a task that is often relegated to mechanics, but there are ways for Grand Prix owners to maintain the discs without paying for the services of a pro. This guide will show you some simple ways to clean and maintain the brake disc of your Grand Prix.

  • Ease up on the brake pedal.

Frequent hard stops will cause the brake disc to overheat, resulting in a myriad of problems in the long run. Some of these problems include a pulsating brake pedal that bobs up and down on its own, “bluing” of the disc, and, in severe cases, cracks on the disc's surface. So if you find yourself driving in a place where you need to do a lot of braking, such as in urban areas with heavy traffic, just go slow to keep the brake temperature at a manageable level. It is also recommended to switch to brake pads with “gentler” materials such as ceramic as they produce less heat when the brakes are engaged.

  • For scored or pitted discs, consider resurfacing.

Pits or scores on the brake disc surface can negatively reduce its performance as well as create an annoying scraping sound when braking. But if the damage is superficial, you might still be able to save the disc through resurfacing. Brake disc resurfacing is basically putting the disc through a lathe and smoothing out the surface by grinding out the damage layer. This process fixes most, if not all, of the problems associated with a scored or a pitted disc, but it comes at the cost of making the disc thinner. It should also be noted that resurfaced discs that get scored or pitted again cannot undergo a second round of resurfacing and must be replaced.

  • Clean up dirt from the brake disc with brake cleaner.

While a bit of brake dust can help the brake pads engage the disc, too much of it may cause the pads to slip. In addition, dirt and other impurities can also scrape against the surface of the disc, resulting in scouring that can significantly affect brake performance. Once the discs have become dirty, it will need to be cleaned with a commercial brake cleaner solution. With the wheel removed, spray a liberal amount of cleaner onto the disc. Let the solution dry on the surface and wipe off any excess with a clean cloth.

The brake discs of your Pontiac Grand Prix are put through a lot of stress and heat, so it's not a surprise that they are among the parts of this midsized sedan that frequently breaks down. And while most, if not all, problems with the Pontiac Grand Prix brake disc are caused by brake heat, they can manifest in various ways. Here are some common problems associated with the Pontiac Grand Prix brake disc and how to troubleshoot them:

Less responsive brakes

If you find yourself pushing the brake pedal harder than usual, it might be due to severe wear on the brake discs. While wear is an everyday factor for brake discs because they produce friction to slow down the wheel, if too much of the disc surface is scoured off, it will require more force than normal to engage the brake pads onto the disc. Brake discs usually feature minimum wear indicators, so it is one of the first things to check once the brakes start to weaken. If the wear has gone past the minimum indicator, have the disc replaced immediately. You should also check the condition of brake pads as well as the brake caliper and brake lines for signs of leaks, as these too can cause the brakes to lose power.

Bluish discs A disc that has gained a blue hue at the surface indicates exposure to extremely high temperatures, which in turn is caused by frequent hard stops or an imbalance in the brake system. And while “blueing” of the disc will not significantly affect its performance, constant overheating will cause it to crack and warp from the heat. If the brake discs in your car starts to look a little blue, have the system checked for proper balance. Make sure that the discs have the same thickness and the caliper adjusted for proper adjustment and clearance as well.

Scored disc

Scoring is caused by foreign objects such as road salt and dirt being scraped against the disc surface, corrosion, as well as worn-out or low-quality brake pad material. While brake discs can still function normally with minor scoring, if the depth of the damage is excessive, the disc must be resurfaced to restore smoothness.
