Brake Light On problems of the 2012 Ford F-150

Our 2012 raptor that we have had since new, with 63k miles, was driving fine when the brake fluid light and emergency brake lights came on and lost all power braking. We were able to get the truck to the dealer without an accident and it was diagnosed with a failed master cylinder which bled into the brake booster. We can update with work receipts when we receive the truck back next week.

Brake vacuum pump failure: used 2012 Ford f150 purchased in October 2016. When we moved in March 2017 to a home with a slight driveway slant, there were daily brake issues where when applying the brake it would feel stiff and fail to stop the vehicle. Upon investigation, we learned that a recall had been done on our make, model, and year of vehicle due to a vacuum brake pump failure, but were told that our vehicle was made at a different plant then where the recall was valid for. On 4/24/17 we took the vehicle in to have it checked out and were told by the dealership that this was "normal" and charged $83. 95 for this. Within a couple weeks we started hearing another loud noise when starting the vehicle and took it in on 5/12/17 where the timing chain was replaced under powertrain warranty. A month later, the service brake light started coming on while driving, but if we stopped and turned off the vehicle and turned it back on it would stay off (for a day or two). We called and were told not to bring it in unless the light was actually on. A week later the light came on and we took it into an auto shop to have the codes read to identify the issue to show the dealership. On 6/21/17 the vehicle was taken in with the readings and at that time we were informed that the vacuum pump had failed and needed to be replaced. Ford refused to pay for any of the service and we were charged $559. 08 for the exact problem the other vehicles had been recalled for and which we were originally told was "normal" to not be able to use the brakes on our vehicle for 20 seconds or so when started. At this time we requested to see what repairs had been done on the vehicle in the past prior to us purchasing the vehicle and our listed below:3/21/16 replace timing chain at bickley Ford;3/21/16 replace vacuum pump at bickley Ford;4/8/16 replace hoses for vacuum pump at bickley Ford.

On December 25th exiting highway entering gas station as I was looking for a parking driving around gas station when I applied the brake I notice it was not stopping and the brake light started flashing. I was able to circle gas station parking lot when I had to put it in nutural and turn the truck off and started apply the brake again after 25 30 feet it came to a stop. Towed the truck to the nearest dealership and when the technician inspected the truck it did not fault. Recieved the truck back December 28th and drove roughly 70 miles later when the same issue occured driving down interstate 20 and had to repeat the same precidure during the gas staion by placing truck in nutural and turning ignition off towed truck to new dealership wont recieve the diagnosis for brake failure till the 2nd of January 2017.

Had this problen from start but did not know it only have 30k miles on 2012 do not have many highway miles but when traveling brake light comes on . Have had checked two times and nothing wrong with brakes. Had Ford ck and found to be vacume leak that has been there for long time when this happens I have manual brakes at best . Ford said not warrentied and 700. 00 to fix . I guess Ford is waiting for someone to get killed before they recall. If anyone out there can help please advise.

The brake fluid light came on and the brakes stopped working. There was no sign of a leak. I filled the master cylinder 2 times within 2 miles and samething continued to happen. I was able to slowly get it to a dealership and it was the booster and master cylinder. No signs of leaks. Immediately stopped functioning.

Riding down the road low brake fluid light comes on and brake light pull over put 24 oz. Brake fluid in drive for 20 miles hi-way same thing pull over master cylinder almost dry. Refill check vehicle for leaks nothing drive 1/2 mile check fluid down half way take truck to dealer say,s master cylinder leaking into booster pump luckily driving early morning no traffic and was able to pull off road quickly could have been disasters.
