Discs, Rotors, and Hardware for Pontiac Grand Prix
Rotors and discs comprise two elements of the braking system in a Grand Prix model Pontiac. Therefore, they are part of one of the most important safety features of your car. If you're a Pontiac Grand Prix owner, it's important to understand how these things function and how you can check them regularly for repair or replacement.How do Pontiac Grand Prix rotors work?
A rotor for a Pontiac car is shaped almost like a bowl and features a flat bottom area with a lip at the topmost part. These rotors act in conjunction with the calipers, pads, and discs included in the vehicle. The pads and calipers press against the rotor when you depress the brake of your Grand Prix. This action provides your Pontiac with the friction it needs to slow or stop the car. The design of most rotors, including those featured in a Pontiac Grand Prix, evenly distribute the heat that the friction creates, ensuring that the moving parts of the Grand Prix's braking cycle do not become too hot. The disc brake of a Pontiac car features rotors that act in this way to provide the force needed to slow your car down.How do you choose Pontiac discs and rotors?
Choosing the discs and rotors for your car needs starts with the model and year of the car. While many of these parts are compatible with various Pontiac models, you'll want to ensure that above all, you're choosing rotors and discs that are specifically made for the Pontiac Grand Prix. While your factory rotors and discs will suffice, there is a variety of aftermarket custom options, including:
- Slotted rotors: These rotors have grooves cut into the sides of the part itself. As dust and gas from the heat of the braking action continue to build up in your Pontiac, the grooves allow this gas to escape, giving the pad and rotors better contact.
- Cross-drilled rotors: Choose these rotors to keep temperatures down, to increase the longevity of your Grand Prix's pads, and to provide superior force in wet weather conditions.
- Drilled and slotted rotors: These rotors provide an aesthetic upgrade to your Grand Prix's braking unit and are ideal if you need to tow a heavier load with your car.
There are basic signs you can look for to determine whether you need to purchase new discs or rotors for your Pontiac car. Regardless of whether any of these indicators are present in your Grand Prix, they are parts of a mechanical system and will experience wear, thus requiring some maintenance and eventual replacement. Many of these signs indicate that you should replace a disc or rotor in your Pontiac Grand Prix.
- You will hear a high-pitched squealing noise whenever you apply the brakes to your Grand Prix.
- If your Pontiac is non-responsive when you apply pressure, it may be indicative of a leak somewhere in your braking cycle.
- Your Pontiac Grand Prix may pull to one side when you stop. This pulling action suggests uneven wear on your pads or the introduction of foreign debris.
- Grinding indicates that the pads have worn down completely and may be damaging your Pontiac's rotors.
