Are your brakes signaling a problem?
Sometimes, your Cadillac vehicle's brakes will alert you when there's trouble. Whistling noises, chirping sounds, and grinding are a few of the indications that brake service may be required. It is important to quickly recognize signs of reduced system performance. Some signs to watch for are:
- Pulsing brake pedal or shaking steering wheel when brakes are applied
- Soft brake pedal
- Squealing or grinding noise when brakes are applied
- Unusual odor at the wheel area
- Excessive brake dust on wheel
Various GM vehicles often come equipped with brake pads that include a small, thin piece of metal 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.
As important as maintaining your engine is, taking care of brake service is just as, if not more important to safe vehicle operation. If you've neglected engine maintenance, then there's a possibility of a malfunction that will bring your vehicle to a stop suddenly. With brakes, a malfunction of a similar scale will instead prevent you from stopping safely. In a machine that often weighs two tons or more, that is a dangerous event that you want to avoid at all costs.
So don't neglect the brake service your vehicle requires. Our service center near Louisville has a team of certified technicians you can trust to understand and care for your car, and high-quality genuine OEM parts for every job. In addition, with our brake service coupons, you can be confident that you're getting a deal.
The Anatomy of Your Vehicle's Brakes
To better visualize the ins and outs of brake service, knowing the parts involved in your vehicle's braking system will make everything a relatively straightforward process to understand, especially if you need replacement parts and auto repair service. When it comes to the vast majority of cars on the road today, a braking system is composed of:
Brake Lines and Hoses
Your brakes use hydraulic pressure to operate. Within the brake lines, fluid is compressed as you press the pedal. From the solid lines, the fluid then runs through a flexible hose to withstand the motion of the wheel hub it is connected to.
The muscle of your braking system, a caliper will connect to the previously mentioned hydraulic lines with the flexible hose. When the fluid in the lines pressurizes, a piston inside the caliper will push out, applying the force necessary to stop the vehicle.
When the caliper piston pushes, it pushes on a brake pad. A metal pad with a friction generating material on its surface, brake pads are designed to wear down over time and are the most common brake service needed.
When the brake pads apply force, they're doing so to the brake rotor. A simple disc at first glance, a brake rotor connects to your wheel and spins with it. When the brake pads grip the rotor, friction brings your wheels and consequently the entire vehicle to a stop.
Signs Your Brakes Are In Need of Service
Knowing all the components in auto brakes will help understand what is involved with brake repair or service, but there are still ways to tell that a service is needed. If your vehicle's brakes are showing any of the following symptoms, contact our brake repair shop to set up an appointment right away:
- Soft and/or spongy brake pedal feel
- Pulsing in the brake pedal and/or a shaking steering wheel while braking
- A grinding, squealing, or rattling noise occurs while braking
- Excessive brake dust buildup on wheels
- Unusual odors coming from wheel well
Additionally, most GM vehicles use a thin piece of metal on their brake pads to warn you when pad material has worn down to the point of needing replacement. This metal piece makes a chirping noise when braking if the material is low. This noise will let you know it's time to come in for a brake service. So browse through our brake service coupons, we may have deals for you when it's time to change out your brake pads.
Brake Service FAQ
How do I know when I need new brakes?
GM Brake pads are equipped with wear indicators that produce a squealing noise when the brakes are almost worn out. The noise may be present with or without the brake pedal applied, but when noise is heard from the wear indicator, the brake pads should be replaced as soon as possible.Wear indicators are set to create noise when there is around 2 mm of brake pad friction material thickness remaining. In the case of assessing pad wear through inspection, pads should be replaced at or before 2 mm thickness is reached.Rotors should be replaced before they reach this minimum thickness and should not be turned below this.
Must I always turn or replace my rotors when changing my pads?
No. If there are no conditions such as pedal pulsation or steering-wheel vibration during braking, and the brake rotor is at least 1 mm thicker than the discard thickness, then it does not need to be turned or replaced.
Do I have to replace my brake rotors after a certain amount of time?
No, but it is a good idea to check the condition of your rotors at every tire rotation.
Why does my brake pedal pulse?
Brake-pedal pulsation and other conditions such as steering-wheel shaking while braking are caused by thickness variation in the brake rotor when a thicker spot of the rotor rotates through the caliper, it pushes back against brake fluid, which can be felt at the brake pedal. The brake fluid and pedal then relax again as the thick spot exits the caliper. This process produces pedal pulsation and “brake torque variation,” which can shake the steering wheel and seats. Brake pulsation is not caused by warping of the disc. However, distortion of the disc due to excessive temperatures or improper installation and torquing of the wheels can lead to brake rotor thickness variation over time. Brake-pedal pulsation is corrected by turning and/or replacing the brake rotors to eliminate the thickness variation.
Why do my brakes squeal? How can I stop it?
Brake squeal is caused by the high-frequency vibration of brake components (rotor, calipers, and/or pads) in response to excitation from the brake friction process. A significant amount of time and engineering goes into eliminating brake squeal from original equipment brake components. Brake components are engineered as a complete system—factory-original performance can only be assured when using original equipment brake pads and rotors. When brake squeal occurs, there may be damage or excessive wear on one or more components affecting noise, including the brake pads, the noise-damping shim that is bonded to the brake pad, or the rotor friction surface.
In addition, it should be recognized that high-performance and track-capable brake systems using high-performance pad materials may be at higher risk for producing brake squeal noise, even when no damage to the components is present.
How long will my brake pads last?
Brake pad life depends on driving habits, vehicle usage, and operating environment. Brake systems are designed to provide 20,000 to 25,000 miles of pad life in very severe use (such as heavy-traffic urban areas) and can give 40,000 to 60,000 miles of pad life in average use. Some factors that will reduce pad life include frequent heavy braking, elevated temperatures (caused by high-speed braking, driving in mountainous areas), driving with the vehicle heavily loaded, and severe environments such as high-corrosion areas and areas with a lot of road debris and dust.
Do metallic brake pads eat rotors?
Yes. Pads with higher metal content will tend to operate with more abrasive friction, where hard metal particles in the pad interact directly with the brake rotor surface. Use of metallic pads will create more brake dust and will shorten the rotor life. Non-asbestos organic pads (also known as ceramic pads) used on most GM vehicles in North America develop a transfer film, a layer of material on the pad and rotor surface that acts as a cushion (at a microscopic scale) between the brake pad and rotor, protecting both from abrasive interaction that causes wear.
My brake pads are very dusty. Are all pads dusty?
Brake dust can occur to some extent on most brake systems, but it is significantly more noticeable with metallic pads and on high-performance brake systems. Brake dust is a mix of debris from the brake rotor, which is the most significant component, and debris from the brake pads. Pad materials that wear the rotor more aggressively will cause more dust.
Are all brake rotors the same?
While brake rotors designed to fit the same vehicle will often be similar in appearance and dimensions, there can be differences in internal cooling vane design, thickness of the brake plates (against which the brake pad rubs), and the grade and material specification of the cast iron. For original equipment brake rotors, significant analysis and testing goes into determining the right geometry to minimize thermal distortion and squeal noise and to maximize cooling. Similar rigor is put into the material selection, which can also affect the risk of squeal noise as well as friction and wear properties.
