Stopping power is crucial to a safe and successful driving, hauling and towing experience. So when you need new brakes, visit your local GMC dealer. Certified Service experts can recommend quality brakes, like DuraStop components from ACDelco.

Whether you need a brake service or replacement, your Certified Service technician can help you get safely - and confidently - back on the road.

Sometimes, your GMC’s brakes will alert you when there’s trouble. Whistling noises, chirping sounds, and grinding are indications that brake service is required. Here are some common causes of brake pedal pulsation and/or noises.

• Worn brake pads
• Heat-cracked or worn rotors
• Loose-fitting brake pads in the caliper
• Missing or damaged noise insulators
• Uneven torque of lug nuts or caliper hardware

Vehicles often come equipped with a small thin piece of metal attached to the brake pad to act as a warning indicator when the pad material is getting low and the brake pads should be replaced. This device makes a chirping noise on brake application, letting you know it’s time to have your brakes serviced.

When you head to your GMC dealer for brake service, you can be sure they can offer a full line of Genuine GM Parts, each one designed and manufactured to exacting standards for your specific vehicle.

If your GMC needs new tires, the Certified Service experts at your GMC dealer can recommend the right tires for your vehicle. They offer a range of top-quality tire brands at competitive prices.

Tire wear depends on several factors, including your driving style and tire maintenance habits. The wrong size load and speed rating can void your warranty. But one sure way to know when to replace your tires is when treadwear indicators appear. A tire’s built-in treadwear indicators are wear bars that look like narrow strips of smooth rubber across the tread and appear when it’s time to replace the tire.

You also need a new tire if:

- You can see three or more treadwear indicators around the tire.
- Cord or fabric is showing through the rubber.
- The tread or sidewall is cracked, cut, or snagged deep enough to show cord or fabric.
- The tire has a bulge or split.
- The tire has a puncture, cut, or other damage that can't be repaired correctly.

Your GMC dealer offers a range of top-quality tire brands: , Bridgestone, Continental, Dunlop, Firestone, Goodyear, Hankook, Michelin and Pirelli.

They can provide tires that meet the specifications for your GMC, so you can buy a new set of tires just like the ones that were on your vehicle the first day you drove it..

Maximize the performance and durability of your GMC’s tires by monitoring and maintaining correct air pressure. Air is a gas, expanding when heated and contracting when cooled. For most of North America, fall and early winter are especially important times for checking tire pressure - as the ambient temperature falls, tire air pressure goes down.

A good rule of thumb is that for every 10 degrees Celsius temperature change, tire pressure changes about 1 psi - higher as temperatures rise, lower as they fall. Check your GMC Owner Manual for recommended tire pressure.

• Premature or irregular wear
• Poor handling
• Reduced fuel economy
  

• Unusual wear
• Poor handling
• Reduced fuel economy

Check your vehicle’s tires at least once a month when the tires are cold (let the vehicle sit for at least 3 hours). Look in your GMC Owner Manual for the recommended tire inflation for your vehicle. Use a quality gauge. Don’t eyeball tires - radial tires can look fine even when they’re underinflated. Be sure to look for objects that have become wedged in the tread - they can work themselves further into the tire and cause air loss. And don’t forget to check the spare!

Since each tire performs different tasks (such as steering or front- versus rear-wheel drive), tires wear at different rates. Rotating your GMC’s tires at recommended intervals extends their useful life, achieves more uniform tire wear.

It’s important to rotate your tires according to the correct tire rotation pattern. Front tires encounter different tasks than the rear tires. And a front-wheel-drive vehicle’s tires perform different tasks than those on a rear-wheel-drive vehicle. Your GMC Owner Manual specifies which rotation pattern is right for your vehicle.

Your GMC’s front and rear tires may also use different pressures - make sure to adjust individual tire pressure to the recommendation for each wheel position. See your GMC Owner Manual for recommendations.

Alignment is critical for ensuring that you get maximum wear and performance from your tires. Poor alignment results from your GMC's suspension and steering system becoming out of adjustment with each other. The biggest indicators of your vehicle being out of alignment are pulling one way or the other as you drive or unusual tire wear. Improper tire inflation can also cause unusual tire wear.

Your GMC may have both front- and rear-wheel alignment specifications. Your GMC dealer can recommend the alignment type that's right for your vehicle.

Certified Service technicians at your GMC dealer are trained to understand how your vehicle uses its oil and how it monitors oil life. So an oil change from a Certified Service technician not only gives you great service, convenience, and a great price, but you also receive the added value of our expertise on the particular GMC model you drive. Head down the Certified Service lane at your GMC dealer when it’s time for your next oil change.

Most GMC vehicles are now equipped with the engine Oil Life System. This system actually senses your vehicle’s speed and engine temperature and can continuously monitor operating conditions. This helps determine when it’s time to change the oil.

This Oil Life System can actually monitor your personal driving habits and your area’s ultimate climate conditions to let you know precisely when to come in for an oil change. When the OLS light comes on, you come in. It’s that simple. It’ll help save you money and help reduce oil waste.

Your Certified Service technician will reset your Oil Life System after an oil change. If you would like to reset the system yourself, ask your technician how, or consult your GMC Owner Manual if necessary. This is also where you’ll find the proper procedures to check your oil level. You’ll get a more accurate oil level reading on the dipstick by following the instructions in the GMC Owner Manual.
