Brake wear on other Sierra 1500 years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2021, 2023, 2024, 2025, 2026.
What this problem usually is
Brake reports cover a wide spread of symptoms. Grinding or squealing is common, and so is a pulsing pedal or a shake through the car when stopping. Others describe pads and rotors worn out long before they expected, a brake warning light, or a pedal that goes soft or sinks toward the floor. The most serious ones say the car didn't stop in time.
What got replaced
Owners who name the part that was replaced mention the booster (13 reports), the ABS module (9 reports), the pads and rotors (4 reports) and the master cylinder (4 reports).
Recalls and investigations
2 recalls on the brakes cover the 2014 model year. A recall on the same system isn't always the same failure, so read the defect text.
If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
The amount of vacuum created by the vacuum pump may decrease over time.

“"Service Trailer Brake System" alert on dash. This is a safety concern for 2 reasons; the first being the chime made to warn the driver is distracting, persistent, and annoying. The second is the trailer brake system is apparently not functioning properly which is a danger while towing.

Should you keep driving it?
This page can't tell you that. 10 of 144 reports involved a crash and 3 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
