Brake light on on other F-150 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: 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026.
What got replaced
Owners who name the part that was replaced mention the master cylinder (24 reports) and the brake fluid sensor (4 reports).
Recalls and investigations
One recall on the brakes covers the 2015 model year. A recall on the same system isn't always the same failure, so read the defect text.
The brake master cylinder may leak brake fluid into the brake booster.

Should you keep driving it?
This page can't tell you that. 1 of 71 reports involved a crash and 1 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.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
