The brake pedal goes to the floor. About a year and a half ago it had all new front pads rear shoes

Hi,

Does it have ABS? If it does, then chances are there is air in the ABS control unit. See pic 1 for directions.

If it doesn't have ABS, check the booster push rod for adjustment. I attached the directions below (pics 2 and 3).

Let me know what you find or if you have other questions. Note: If the master cylinder is new, bench bled, the brake system was bled, there are no leaks, proper adjustment of the pushrod has been made, and this doesn't have ABS, the new master cylinder may be bad.

Let me know what you find.

Take care,

It has rear ABS only.

This is a symptom that went from everything is okay and normal with a good pedal to dropping to the floor with very little braking.

Hi,

I just read through things again, and rear ABS applies. Also, the RABS valve is involved for b bleeding.

I attached the directions below. I highlighted important areas of concern.

It requires special "Ford" tooling to complete. I looked up the part numbers indicated, and I feel you may want to find someone that has them. They are expensive.

Take a look through the attachment and let me know if it helps. Also, let me know if you have other questions.

Take care,

Joe


See pic below.

Joe, thank you.

You are very welcome. If you have a chance, let me know if that takes care of the problem. I hope it helps.

Take care,

Joe

I have an appointment with the local dealer.

I gave it one more try. I found the right rear drum brake adjusted spring had failed and the adjuster became dislodged. I replaced a couple of parts and the brakes now work normally again.

That makes perfect sense. Chances are one of the brake shoes wasn't seated on the wheel cylinder, correct?

Regardless, I'm glad you found the problem. Take care of yourself and feel free to come back anytime in the future.
