Advice From Your GMC Dealer: Signs You Need a Brake Repair

A healthy braking system is essential for safe driving. Your brakes give you complete control over your car's speed and allow you to stop exactly when you need to. Your car's braking system requires regular servicing to keep it in good condition, as parts will inevitably wear out due to age. As your GMC dealer, we'd like to advise you on some signs that you need to visit us for a brake repair.

Your Car Pulls to One Side

When your braking system is in good condition, each wheel will stop moving when you hit the brakes. If you experience your car pulling to one side when you brake, this is a sign that there's a problem with your braking system. In this situation, one of the brakes doesn't apply correctly, and your car turns in the direction of the working brake.

When you apply the brake, brake fluid is pumped into the brake hoses. This fluid generates hydraulic pressure that forces the calipers to close on the wheel rotors. The calipers generate friction against the rotors, which causes the wheels to stop moving. A damaged or jammed caliper may not close on its rotor, and the wheel will continue to move. We'll identify the cause of the problem and repair it.

Screeching Sounds

As we saw above, the action of braking forces the calipers against both sides of each of the rotors. The calipers house the brake pads, and the brake pads generate friction that stops the movement of the rotors. The pads are covered with a 1/2" thick friction material covering that produces the required friction. The friction material wears down very slightly each time you brake.

When a pad drops to 1/4" thickness, a metal spike becomes visible inside the friction material. A spike provides a warning that a pad needs replacement. The next time you brake, the spike will scratch against the rotor, which produces a loud screeching noise. When you hear this sound, it's time to visit us for replacement pads.

Soft Brake Pedal

The braking system operates under high pressure to ensure your brakes work as speedily and efficiently as possible. When you step on the brake pedal, you'll feel resistance from the pressurized brake fluid. The resistance from the fluid increases as you apply more pressure to the pedal. If you step on the pedal and you don't feel resistance, this is a sign of a serious problem.

The lack of resistance from the pedal means that the braking system is operating at low pressure. If the braking system doesn't have enough pressure, your brakes will be slow to apply or may not apply at all. We'll examine your brakes and fix the cause of the problem.

If your brakes are worn or damaged, call us right away at Hart Motors GMC.

GMC Winter Prep: Ensuring Your Vehicle Is Ready for the Cold

Cold winters put additional demands on various systems, but these can be reduced by preparing for them. As your GMC dealer, we want to advise you on a few types of GMC maintenance that will help your vehicle perform easier and more efficiently in the cold days ahead. more From Your GMC Dealer: GMC Maintenance To Prepare You for Winter Battery Check The battery is one of your vehicle's most important systems, as without it, you could be stuck looking for a jump-start. The battery provides the electrical charge that powers the crank, allowing the combustion process to start. They have a working life of three to five years on average, but as a battery ages, its electricity storage capacity drops causing, it to weaken and eventually fail. Low temperatures cause the battery's electrolyte solution to partially solidify. This reduces its power by 20% or more, which can cause an old battery to fail. We'll test your battery by hooking it up to our computerized battery tester. This machine gives a clear indication of the battery's remaining strength. If your battery is weak, we can quickly install a new one to ensure your engine starts easily. Oil Change Engine oil is the lifeblood of your engine. It's pumped through your engine by the oil pump and lubricates countless components. This lubrication protects them against friction damage, reducing wear and tear on your engine. It contains various additives that break down deposits to keep your engine clean and prevent rust from forming. Oil accumulates dirt and other debris as it moves through the engine, causing older oil to move more slowly. This reduces its efficiency, leading to an increase in worn components. Low temperatures worsen this situation as they cause the oil to thicken even further. Our technicians will fix this problem by draining your oil, replacing the oil filter to improve oil flow, and then refilling your engine with fresh oil. Tire Checks Your tires experience wear and tear daily as minute pieces of rubber break off due to surface friction. As the tread wears down, it grips the surface less securely, increasing the stopping distance when you hit the brakes. The rubber in older tires gradually loses its flexibility, and this can cause racks to form on the surface. As time passes, these cracks reach deeper into the tire and can cause a leak. Low tread makes gripping snowy or icy surfaces more difficult and your car could slide. We'll examine your tires and replace them if they're worn. New tires will provide a more secure grip on the surface and ensure you can drive safely. Book your winter maintenance by contacting our service department today at Hart Motors GMC in Salem, VA.

The GMC Towing Guide: How to Harness Your Vehicle's Full Potential

Image via GMC Many GMC vehicles are perfect for towing heavy cargo. While the needs of each individual and trip are likely to vary, there's sure to be a truck or SUV at your local GMC dealer that suits your towing needs. Whether you're interested in the rugged Sierra HD or the powerful Yukon, here's a towing guide to help you make the most of your new vehicle. more Towing Guide for Vehicles From Your Local GMC Dealer Check Your Capacity Each ​vehicle has a specific towing capacity and overall weight limit ​listed in the owner's manual. These capabilities can even vary within the same model based on the trim levels and options selected. Once you learn the overall weight limit of your vehicle, ​check the weight of your trailer, and be sure any cargo added to the trailer and/or vehicle don't put you over the limit. Interior cargo and passengers also count toward the overall weight limit, so if you find that you're coming close to the ​weight limit, consider cutting back or making ​multiple trips. For all the nitty-gritty details about the latest GMC tow ratings, check out the brand's trailering guide. Evenly Distribute Weight ​As you load your trailer with cargo, be sure that items are evenly distributed along the left and right sides to prevent the trailer from veering off to one side throughout your trip. Additionally, weight ​should be fairly evenly distributed between the front and back, with ​any extra weight toward the front of the trailer. This can prevent a heavy back-end from swaying ​side-to-side as you accelerate. Keep Tires Inflated Properly inflated ​tires ​ensure that your vehicle is traveling efficiently. ​Low tire pressure can force your engine to work harder than necessary to power your vehicle forward, ultimately lowering your towing capacity and putting extra strain on your vehicle. New GMC vehicles have tire pressure alert systems to let you know when it's time to add extra air. However, before long trips, it may be worthwhile to check your tire pressure manually and compare ​it to the recommended level listed in your owner's manual. ​Don't forget to check the tire pressure on your trailer as well. Utilize Helpful Safety Features ​Many GMC vehicles come equipped ​with impressive tech features that allow you to keep an eye on your trailer and around your entire vehicle as you tow. For example, the Sierra 1500 and Yukon come with trailer blind spot ​zone alerts ​that let you know if a vehicle enters the blind spot around both your vehicle and trailer. If you're ready to experience the towing power of a new GMC truck or SUV, contact Hart Motors GMC at 1341 East Main Street in Salem, VA. Our friendly team can help you understand all the options available that suit your hauling needs and make the most of the powerful features that come with these various models.
