Brake fluid is leaking out of the master cylender and into the brake booster. Causing low brake fluid in the resivore. And resulting in no brakes. There are recalls for this issue with the 2013 modles. This should be extended to the 2010 modles.
On October 5, 2021 (Wednesday) I was driving my 2010 F-150 lariat and noticed the brakes fading as I came to brake for red lights. I also noticed “brake warning” lights & “brake fluid level low” light come on also. I pulled into a cvs store and looked under the hood to & saw the “master cylinder brake fluid reservoir” nearly empty. I put 1 bottle of dot 3 brake fluid in fluid container and saw level go back down, almost empty, upon turning truck on to pressurize the system. I didn’t see any fluid leaking from under truck & bought another bottle of dot3 brake fluid and again the reservoir emptied again. I got the vehicle home and the next day the same thing happened after a 3rd refill of the reservoir. Again still not seeing any fluid leaks on my driveway!!! I disconnected a vacuum tube at top of “brake booster” which is connected to the “master cylinder” and looked inside to see large amount of brake fluid in the “brake booster housing”!!! I saw where 2014 to 2017 Ford F-150’s have been recalled for this exact same safety issue! I will contact my dealership for immediate repair tomorrow, October 7, 2021. . Read more...
Brakes did not work without warning as Ford f150 2010 pulled from the driveway. Pedal was depressed to the floor without any brake function or warning light. Stopped the truck with parking brake. Truck had to be towed to the dealership. Brakes worked hours before in traffic. The dealership exchanged the master brake cylinder and the brake booster, in which the brake cylinder leaked fluid into.
While driving down a city street, the vehicle was suddenly unable to stop because the brake pedal was pushed all the way to the floor with complete brake loss, and the brake fluid warning lamp suddenly illuminated. The emergency brake was able to stop me and allow me to safely pull over. No fluid leakage was discovered upon initial look but the reservoir was empty. The solution involved locating the missing brake fluid which had leaked from the master cylinder into the brake booster, resulting in the brake loss. Upon replacing the defective master cylinder and brake booster, the brakes are okay now. This problem is identical to the summary identified under investigation pe-16-003 (see attached).
Traveling at 45 mph on a highway I applied brakes to slow down when the brake fluid level warning light came on. Brake pedal went all the way to the floor before slowing the vehicle, had to downshift and apply the emergency brake. Towed vehicle to the dealer where it was determined the master cylinder failed drawing brake fluid into the power brake booster. No visible sign of a brake fluid leak. Master cylinder and power brake booster must be replaced. Vehicle has 80,000 miles . Sounds like the same problem in a recall on 2014-15 f150 but no such recall for the 2010 f150.
The contact owns a 2010 Ford F-150. The contact stated that the front brake pads froze to the rotors causing the caliper to separate. The failure damaged the pistons and caused brake fluid to leak from the master cylinder. The contact was able to engage the emergency brake. The vehicle was towed to the local mechanic and the brake calipers, pads, and rotors were replaced. The manufacturer was made aware of the failure. The failure mileage was 108,000.
Just after starting the engine the truck was driven out of the driveway and at the first press of the brakes the vehicle was not stopping. After bearing down on the pedal with full force vehicle came to a stop. Brake warning appeared in the digital message center and the abs light came on. I pumped the brakes and a very tight pedal indicated the vacuum assist had failed. I also could hear a hissing sound at the press of the pedal. I restarted the engine and pulled the vacuum line off the booster and the distinct vacuum pop was present. I began removing the booster, I then realized brake fluid had leaked out of the rear of the master cylinder and into the booster. I believe the corrosive properties of the brake fluid ruptured the diaphragm inside the booster. There was about 5 oz. Of fluid inside the booster. I ordered and replaced the booster and the master cylinder. This is too new of a vehicle for a brake system failure. Someone is going to be killed if this issue is not corrected.
