Re: 99 Taurus Brake Problem
I'm having this same issue. Had the brakes done at ford, 18 months later, got this nasty warbling noise out of the left rear brake when going slow with foot OFF brake.
Took in to meineke, took 30miles of driving to heat them up to exhibit issue. They replaces calipers (reman oem), did the discs, etc. Pads had melted to the discs.
Week later, still making noise. Took back in, they found the emergency cable maladjusted. Fixed that. Ok for the most part but the car still seems to drag, and makes noise once every 3 weeks now when cold, not hot. is a "whoo whoo whoom whoom whoom" noise until i apply the brakes.
Took into ford, they blamed the calipers. Of course it had THEIR calipers on from the previous repair at their place 20 months ago. So I don' buy it.
Could I be suffering from this valve issue also? Everyone is at a loss and they want to fix it while it is making the noise but it is very random now, and the car still seems to drag, even those the discs look clean.
