Bleeding problem
This is my first post, so hello everyone.
I have a 99 f150 5.4 triton. I just did a full brake job on it, including pads, rotors, calipers all around. Started at the right rear and disconnected brake line first ( mistake) in the time it took to Change the caliper and pads, the mc was drained dry. When trying to beat the rotor of, I had to turn it to beat the othe half so I put it in neutral which meant I had to push the brake (another mistake) I went ahead and finished the job, bled the system, and the pedal goes straight to the floor when started. I broke down got a new master cylinder, bench bled it, installed it, bled the mc fittings, then bled the calipers. Same thing, to the floor. I have done several brake jobs on this truck in its 125,000 miles and never had this much trouble bleeding brakes. At this point I have ran 6 qts of brake fluid through it trying every method available to me including pump & open, vaccume pump, gravity, speed bleeders. I am at loss, any ideas? Thanks |
If you have 4 wheel anti lock brakes you have air trapped in the hydraulic control unit that has to be bled with a special computer interface, NGS is one and IDS is another. No other way around it.

I was afraid of that, guess Its off to Midas to have it bled, I hate that.
Just for future ref., was it because I mashed the pedal when the mc was dry? |

I would take it to the dealer. I don't know if Midas would have the tools for that.

Texasedition is exactly right, there is no mo local shop that has the software Around here. Ford wants $200 + to do the job. After being bent over by this dealership before, I'm trying to find another way.
Reading on other forums I found a trick by some saying to go to a gravel road, get it up to 35 mph slam on the brakes to activate abs pump, Do this 3 or 4 times then bleed calipers again, it will purge the air out. Anyone heard of this, or if it's true? Can I screw something else up? Thanks agiain |

Rnlcomp, thank you, I'm in NC, but it may be Cheeper to drive to the big easy (and more fun) but, are you saying its worth a try, or don't risk it and bite the bullet and pay big for my mistake?

I don't cut any corners when it comes to brakes. It's one thing to have a poorly running vehicle, it's an entirely different situation if you can't stop the pig. Pretty big hunk of Detroit iron.

Agreed, guess I'll get out the vaseline
