I had a 2013 Lincoln MDX with 131,000 miles in the shop today and repaired the same Customer Concern soft brake pedal.. I did not replace the master cylinder, or the A.B.S. valve block, or pull the battery multiple times.. Now I'm home after work and Googled on the UA-cam... Your video was the first to Pop up.. Your final diagnosis of a stuck valve in the A.B.S. block was probably correct.. I performed the auto bleed procedure and the pedal may have felt slightly better?.. Before condemning, or falsely diagnosing a faulty master cylinder,, pull all 4 wheels and remove the mounting bolts from the brake caliper's.. Be sure that none of the sliding bolts or bushings are seized.. Crack open the bleeder screws "just gravity bleeding" and look for air bubbles.. NOW HERE WAS THE FIX!!.. Get another person to help on the brake pedal and manually bleed the flush the brake fluid system.. When I bleed the Left Rear caliper,, the brake pedal felt normal, and as good as new... Moral of the story is "Flush the brake fluid, because one of the valves is Stuck in the Muck!"
I actually took the ABS block off of this MKX (not shown in the video) and attempted to do a bench clean/flush, and then reassembled and bled the brakes, and still had no pedal. Mine was REALLY REALLY stuck. Thanks for the comment tho!
Thank you for this great video very informative I have my wife’s 2013 ford edge with low B pedal Iam in process of changing the master and Iam hoping it will get the pedal back up if not then off to abs block wish me luck thanks again great video I appreciate you
I left a comment yesterday, and called one of my best friends.. He's a retired Ford Master Technician.. He told me "Flushing the brake fluid was the best thing I did" Auto Bleed and Manually Bleed all 4 corner's.. The best place to start is Cover The Basics 👍
Just did my 2013 MKX. Bit the bullet. Brake pads, rotors, master cylinder, abs thingie, trinkets and rubber. $1,600 bucks. We keep cars for 20 years. Wife’s car is an 03 T-Bird. It is perfect. Last year I replaced everything that could be unbolted under the car. It is, essentially, new. Plan for it, save the money, get the work done right.
On my 2013 Ford Edge sometimes the brake pedal will go soft after a hard braking event. Running the auto bleed function in Forscan always solves the problem...until the next hard braking event. Hopefully, flushing and bleeding at the four corners will prevent the problem from recurring.
Well, the Forscan bleed trick stopped working when the brakes went spongy again. Took it to the dealer for the replacement of the booster under the extended customer satisfaction program, but there was no real improvement in the spongy pedal. I just ordered a new HCU and will be doing the same job as shown here. This video has been a great resource.
This video helped immensely in replacing the HCU. Thank you! New HCU followed by 2 rounds of HCU bleeding (with Forscan) and manual bleeding at the four wheels fixed the problem. After I finished the job, I wondered if it would have been worth it to remove that transmisssion cooler line. That thing was a real PITA as far as being in the way to get to those battery tray support bracket bolts. Also, the only way to get to that bottom HCU mounting bolt was from underneath the car which worked nicely with a long extension going back to front from behind the front crossmember.
We replaced the master cylinder (via mechanic) and it seemed to fix the problem but now it's back. I have no idea if they bled the breaks. Do you suggest starting there?
Good afternoon! We replaced master cylinder on Lincoln 2012 mkx we did forget to do the bench bleed before ,oops wasn't aware so removed it bench bleed then did all 4 wheel bleed no brakes still then did gravity bleed and still no pedal
We did do full bleed prior to removing the master to do bench bleed once we realized that had to be done! And also my car would have a good pedal and then here and there it would seep all the way down and stop barely but then you could pump back up and it would last for days ,months before it would happen again,and we we pulled into the shop brake pedal was firm now we have no pedal at all!!
@@lisabryant3696 we started with Master cylinder on this one, but never could get the pedal to feel mormal. I tried every trick in the book, and then I end up having to replace the ABS valve block to get the pedal feel back

Certainly doesn't hurt to start simple (and cheap)
Great video, very clear as to what to do step by step! Thank you very much
You're welcome! Hope it helped you out

Quite the investment, but still cheaper than a down payment on a new one 😆

You probably have an intermittent sticking valve. I hope that you can limp it along for a little while longer!

Did you by chance look into disassembling the ABS module to look for stuck valve?
the thought crossed my mind, but I never did
Did you have reprogram the unit, or, because you just changed what appears to be the mechanical portion of the ABS unit, no programming was required?
Correct, no programming. But the Forscan does help to do the ABS bleed portion
We replaced the master cylinder (via mechanic) and it seemed to fix the problem but now it's back. I have no idea if they bled the breaks. Do you suggest starting there?
likely needs an ABS valve block, not a master cylinder
UGH, I'm getting ready to do the same thing. Now I know what i'm in for.
yah, its really not that bad tho. just the ABS control unit is expensive!!
@@Patman03sprcrw so where is the best place to buy from?
I picked my up from Ford, but I'll be honest I didn't really price shop anywhere.
Tasca online parts usually has good prices too
Replacing the master cylinder did absolutely nothing for mine if I take a sharp left U-turn my brakes go right to the floor for days
did you do full ABS bleed and brake bleed?

@@Patman03sprcrw I sent few comments hope to hear back! Thank you

you should change your water-pump before your engine is junk!
I've personally done a few of them. It's a big undertaking!
