When ordering my 2026 I road tested and inspected a 2025. The master cylinder is not the typical hydraulic with a vacuum chamber but the new, electro hydraulic unit used on most cars. That being said, remember than you aren't pushing on a cylinder that directly acts on the slave cylinders but rather pushing on a dummy cylinder for driver feed back so it feels like you are applying the brakes. There is a linear actuator in it that actually applies the brakes. The dummy cylinder can power the slave cylinders in the event of a system failure though. When I was at BMW we switched to this back around Covid time and for BMW it was a comprehensive pile of ****. TONS of recalls and complete unit failures which unfortunately bricks the car. Hopefully the ford programming isn't as dumb as the germans get. Do keep in mind that this completely changes the pad replacement procedure in cars with this system.

 

Yowsa! Brake by wire? Thinking "No thanks!"

 

My 2025 stx 4x4 brakes are top notch and confidence inspiring. Especially while towing.

 

everything is going that route because the ABS is integrated into the master cylinder. It’s cheaper and gives the he ABS more control. Remember, the dummy cylinder becomes the active cylinder for operating the brakes with a system failure. They aren’t like normal brakes but you can stop.

 

Well just got back from a trip towing my 22' trailer with 2 side by sides on it. The pedal is spongy and requires alot of force to stop. I wasn't comfortable with it at all but at least my trailer has brakes on it. I guess I'll start looking at aftermarket options. I only have 19,000 miles on it so this sucks.

 

Have you looked under the dash at where the brake pedal pushrod goes into the master, I've seen on about 5-6 of them over the last 2 years of 30 cng conversions they were leaking and this was on new trucks with less than 5k on them. I know of one for sure that had the master replaced under warranty.

Other things to look at:

Bleed brakes
Check the pins are moving freely and not seized
Check the pads aren't too tight/seized in the brackets
I recently ran into bad rear calipers on a mustang that wouldn't self adjust and had weak brakes the distance between the pads and the piston was too far and you felt the pedal drop before they'd do anything, replaced the calipers, bleed brakes and the customer was extremely happy and said they haven't felt that good since new.

 

I haven't, I've had it in the dealership twice for the brake issue and had them look at it during regular maintenance and they always say they checked them and there is nothing wrong.
