    Hello everyone,

    I just replaced the upper and lower ball joints and did the brakes all the way around on my 2006 F-350 Super Duty 4x4. I did have to replace one rear caliper which I did and bled out. The rest of the job went pretty well but now my brake pedal does not hold. I can pump up the brakes but the next time I apply them the pedal goes low again. I did go back and bleed all 4 starting at the furthest from the master. I'm not that famillier with these new anti-lock systems can someone help. Thanks for the anticipated responses.

    I'm not too familiar with the ford but had a similar problem with my chey. The rubber piece in the master was not seated correctly. Might check that.
