How to Reset the Service Brake Pad Monitor on Your 2019 GMC Sierra

If you notice that the brake pads on your 2019 GMC Sierra are becoming worn down, it’s time to get new ones. There are some things that you can do to avoid a costly repair. First, disable electronic brake assist. Next, reset the service brake pad monitor.
Disabling electronic brake assist
The 2019 GMC Sierra’s service brake pad monitor alerts a driver that the brakes may need replacement soon. Some owners have reported the warning light coming on unexpectedly, which GM has linked to a power brake assist issue addressed through a service bulletin. If the light appears alongside reduced brake performance, it’s best to have the vehicle checked at a dealership promptly.
The first step is to disconnect the cable from the positive terminal of the battery. Then, hold down the brake pedal until the stored electricity is discharged. Reconnect the cable and restart the vehicle. If the warning light comes back on, the problem is likely related to wiring rather than the brake pads themselves.
In some cases, this message is accompanied by an ABS or traction control light. In either case, you must visit a mechanic for a diagnostic test. These diagnostic procedures can cost upwards of $100. However, if you’re confident in your skills, you can try to replace the sensor yourself.
Resetting the service brake pad monitor
To reset the service brake pad monitor, first disable the electronic brake assist system as described above. With the vehicle parked safely and turned off, disconnect the positive terminal cable from the battery. Press down on the brake pedal until the stored electricity has been expelled, then reconnect the cable and turn the car back on. Check whether the warning light has gone out.
The 2019 GMC Sierra 1500 comes with service brakes that are less than reliable. This has caused a number of frustrations for many owners. A service bulletin has been issued to address this problem, but there’s still no recall. One problem is that the front brake pad guide pin may be missing a cotter key clip retainer. It’s unclear why GMC has not issued a recall.
A reset of the 2019 GMC Sierra service brake pad monitor is a straightforward process. The system uses a number of sensors, including front and rear pad thickness sensors, to estimate brake pad life. When the brake pads are worn significantly, the system sends a warning message to your vehicle’s DIC. This message may also include how much mileage you have left to drive. To prolong the life of your brake pads, try driving carefully and avoiding hard stops.
Cost of new brake pads
The cost of new 2019 GMC Sierra service brake pads varies. The basic cost for replacement is $350. The more comprehensive package includes a new brake rotor and new brake pads. It also includes lifetime labor and parts warranties. A full brake service can cost up to $470.
When it comes to brake pads, it’s important to have them replaced on a regular basis. Newer vehicles will display a warning light when brake pads are starting to show signs of wear. The light will come on when the friction material in the pads has worn to about 2 mm of the pad backing plate. You can also refer to your owner’s manual for more information. If you’re unsure of when to replace your brake pads, read the owner’s manual for your specific model.
If you’re looking for an affordable way to get your GMC Sierra service brakes working as they should, you can purchase online or from your local mechanic. The price will vary depending on the model year and the area where you live. Brake pads typically cost about $50 to $100 per pad. The price also depends on labor costs, which vary widely by region.
Symptoms
The 2019 GMC Sierra service brakes are not as reliable as they should be. Many owners have been frustrated with the brakes on their vehicles. According to the Service Bulletin, one component of the front brake pad guide pin may not be attached properly. While GMC has not issued a recall for this problem, it is a known problem. Here are some of the symptoms that you should look out for.
If you experience any of these symptoms, it’s best to have the vehicle checked at a GM dealership for repair under the applicable service bulletin.
Another symptom of a brake problem is uneven pad wear. If you notice uneven pad wear, it is time to replace the brake pads. You should also check your 2019 GMC Sierra’s maintenance schedule to see when it is time for brake pad replacement.
