Brake booster failure 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, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
This is the narrower sheet inside brakes for reports about a hard pedal or a failed power assist. The pedal stops feeling normal: it turns stiff, takes far more force, and the car needs a longer distance to stop.
What got replaced
Owners who name the part that was replaced mention the brake booster (137 reports), the master cylinder (116 reports) and the vacuum pump (3 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.
The brake master cylinder may leak brake fluid into the brake booster.
The master cylinder rear cup seal may roll, resulting in brake fluid leakage from the primary reservoir into the brake booster.

What owners wrote
“I was driving and my brakes gave out a bit and my brake pedal was hard to press down and when I pressed down there was a grinding sound. Also a red warning message said check braking system. Has been confirmed for 3.5L EcoBoost engines, which is what I have.”
Filed Apr 28, 2026
“While driving the brakes failed and pedal was to the floor. No warning light before this happened. Warning light eventually came on after the failure. This was a very scary situation. Vehicle was taken to auto repair shop who confirmed it is a failure of the master cylinder and brake booster.”
Filed Jun 30, 2025
“The master cylinder failed and caused brake fluid to be sucked into the vacuum brake booster. The result is total hydraulic failure of the brakes and a safety hazard. This is a known failure for the 2014 F150's with the 3.5L Ecoboost for which there was a recall. My truck with the 5.0L motor uses the same part.”
Filed Feb 23, 2024
“Vehicle failed annual State (VA) safety inspection on 7/13/2023 due to Power Brake Booster issue. I see there is a recall out (NSTA#20V332) on Ford F150 for this issue but not on my VIN. Brakes are mushy and stopping time is increased.”

Should you keep driving it?
This page can't tell you that. 3 of 146 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.
