My 2007 Mercury Mountaineer Brake issues

My 2007 Mountaineer had spongy breaks. So I replaced the power booster as indicated by the manual's troubleshooting steps. Now the breaks work fine, but the break pedal does not actuate the break light switch any more. It doesn't seem to be in a different position. It just doesn't contact the switch any more.

Is there an adjustment to the switch? Is there something missing that should be attached to the pedal? Does anyone have any pictures of the pedals under their dash?

Did it move some while you worked under there? Tell me how the breaks improved. just got an 06 EB w/ 93k and it seems like it takes more foot on the pedal than it should . Is that what yours was like ?

Ford has tsb for this concern.

what the newer break pedal doing differently? seems kinda wierd but if it works it works right?

So far the breaks seem to work fine. The interesting thing is that the switch for the break lights does not make up any more. It is still there and works fine, but it is not actuated by the break pedal coming back to the rest position. However, this was a simple fix. I just got two small magnets from a hardware store here and put them on the brake pedal arm and it completes the distance between the pedal and the switch. All is well with that.

Now there is a new noise. When the car is in park, and you push the break pedal there is a clicking sound at the gear shift. It sounds like a relay changing state. It seems that it must be the switch that keeps the car in park until you push the brake pedal in. I am not sure how to replace this or trouble shoot it.

However all the rest of my brakes are working fine. The ABS light went out on its own after I took it to a mechanic and he reset it, it came back, but went away after a day or so.

SUPERINSTALLER: There is a procedure in the Chilton's manual on this car that involves pumping up the brakes and turning the car off an on. When I did this procedure it indicated that my power booster was not air tight so I changed it out and all seems to be working fine. I did not change the pedal in any way. I am not sure why it is doing this, but the magnets seem to work fine.

SWETRID: Thanks for the information. I have bled my brakes and that took out all the air. Very helpful.
