2016 Ford F-150: soft or spongy brake pedal

Filed Jul 6, 2023 · Brakes · TX

I came to an intersection and stopped. While my foot was on the brake pedal it became soft after 5 seconds and then was depressed to the floor board. While remaining stopped I pumped the brakes and they continued to be soft and spongy. I then proceeded through the intersection and proceeded to enter Interstate 10 just outside of Luling, TX. While traveling at 70 mph I tried my brakes again and quickly realized I didn’t have the ability to stop. I slowed my speed, found the next exit ramp and pumped my brakes and down shifted to bring my 2016 Ford F-150 to a stop on the shoulder. While stopped I pumped my brakes again and the brake pedal went directly to the floor with no resistance. My truck was not safe to drive so I had it towed to the nearest town of Luling, TX. The mechanic diagnosed the problem where the rubber brake line on the right front wheel had ruptured causing the loss of hydraulic pressure and fluid.

Brake pedal is hard to push down and doesn't work. Pedal is stuck high then slams to the ground with no warning. On several occasions I have almost rear ended the vehicle in front of me. This is a safety issue for myself, my children, and other drivers. This has happened numerous times. Ford has a recall for this same reason on other years and models of the Ford F-150. They need to include the 2016 in the recall as well. There is an internal brake fluid leak. I have taken to local dealer and they tell me there is no problem. When the brakes fail there is no warning, no lights, no chimes, nothing.

Vehicle operating normally until problem noted 7/13/2016. Vehicle purchased used from certified ford dealership on 5/16/2018. Currently has approximately 44,800 miles on odometer. Vehicle has been parked overnight and upon am startup and backing up suffered complete loss of braking ability when brakes were applied. Low brake reservoir indicator light on. Visual check revealed reservoir level well below minimum mark and level with inlets for the brake lines. Refilled, pumped brakes and able to obtain moderately firm pedal. Started vehicle, let idle few moments, tested brake pedal but found soft pedal again sinks immediately to floor and reservoir light on again. Visual check shows fluid again has emptied as described above. Vehicle had not been moved. A visual trace of all brake lines shows no external leakage along length of the lines nor at any brake component. Fluid is obviously being drawn into the vacuum boost reservoir. Vehicle has not been altered in any way from date of purchase. This is an extreme safety issue with a high probability of loss or life and/or severe injury to passengers and/or collision with other vehicles or objects due to this sudden, total brake failure. This is a catastrophic failure of the master cylinder system that produces a failure of the redundant braking arrangement (I.e. Separate front and rear brake systems). This appears from a quick google search of other complaints to becoming a known problem. Prompt action is urged by the federal safety agency to initiate a recall to correct these problem for obvious safety reasons.

On 8-19-17 truck was moving at about 30 MPH on a street, went to stop at a stop sign, brake pedal went all the way to the floor, truck would not stop. Released brakes, and tried again, this time pumping the brake pedal. Truck stopped this time. Continued on, brakes felt spongy but would stop and started feeling normal again. On 8-26-17 same scenario occurred. Dropped truck off at ford dealership on 8-28-17. As of 8-31-17 dealership has not duplicated problem, found any fluid leaks and has not solved problem. Just a side note. My brother in-law has the same exact truck and experienced the same situation about a year ago. At that time the dealership replaced the master cylinder and has seemed to solve his problem. I have also googled this problem and it seems to be a problem with other owners. Some have had the master cylinder replaced. I suggested this to the service writer at the dealership, service writer has declined to replace master cylinder since they can not duplicate problem or find any leaks.

When approaching a stop light, my brake pedal just went to the floor. I made it to a parking lot with spongy brakes. Once in a parking space, when pressure was applied to the pedal, the pedal slowly went completely to the floor.
