Leaky master cylinders are causing a sudden loss of pressure in the F-150’s braking system.
Brakes really thrive under pressure, it’s what pushes the pads against the rotors and keeps your brake pedal from falling to the floor. You know, little stuff like that. In a twist, it’s Ford that finds themselves under pressure from a California lawsuit looking for an expansion of a previous master cylinder recall.…keep reading article "Lawsuit Says Ford Should Expand a Previous F-150 Master Cylinder Recall"
Anyone out there having trouble slowing their truck down?
There’s a lawsuit that says a change to the F-150’s master cylinder design is creating a dangerous braking situation.
All 2013-2018 Ford F-150s use master cylinders supplied by Hitachi, with the pistons fitted with just a single cup seal responsible for containing pressurized brake fluid. The lawsuit alleges this is unusual because pistons within master cylinders are usually fitted with two cup seals to ensure that fluid does not leak out of the master cylinders.
These single-seal master cylinders have already been recalled for the 2013 and 2014 model years. But instead of changing the design, Ford replaced the defective part with – I bet you can see where this is going – new defective parts.keep reading article "The F-150's Single-Seal Master Cylinder Design is Doomed to Fail"
Ford owners sure do love their trucks and they just can't seem to stop talking about them.
It also turns out some of them just can't stop thanks to widespread brake issues.
Federal safety regulators are investigating 2015-2016 Ford F-150 trucks after reports of brake pedals going to the floorboards, a complete loss of brakes and dealerships diagnosing the problems as caused by faulty master cylinders.
We've all heard about putting the pedal to metal, you just never want that to happen with the pedal on the left.
If all this master cylinder / brake talk sounds familiar, it's because the 2013 and 2014 model years were recalled for the same issue earlier this year. I guess that's one box still unchecked on the Ford engineer's to-do list.keep reading article "2015-2016 F-150 Brakes Under Investigation"
F-150 owners can't stop their brake pedals from suddenly falling to the floor. That means they also can't stop their trucks.
The problem is an empty master cylinder resevoir that's hard to detect because there's never any corresponding brake fluid leaks. It's like a magic trick that no-one finds amusing.
A new investigation hopes to pull back the curtain:
"The no-leak symptom is what makes NHTSA believe the fluid is moving from the master cylinder to the brake booster. In addition to that, some owners told NHTSA that Ford dealers have said the same thing."
The investigation covers 2013-2014 F-150 trucks equipped with 3.5-liter engines. If the problem is confirmed, it should prompt a recall.keep reading article "Master Cylinder in F-150 Brakes Under Investigation"
