I have a 2000 Mercury Villager doing the same thing Lf wheel drags after it gets hot, problem was abs modulator, after I replaced Lf caliper, brake hose etc it still was dragging abs modulator has filters in it that get clogged and will not release.
Notorious drivers side caliper lock up. I hate that,,LOL.... Testing your lines are simple. Unscrew the bleed valve, pump the break a few time making sure all lines are clear. If so you will have fluids squirting all over,lol. That also gives indication that your ABS unit is okay to. Free flowing fluids is a good sign. The calipers are known to lock and break. If your fluids are are flowing out the bleed screw then it is most likely the calipers. Buying the more expensive ones in this case is best. If you keep buying the same part from the same manufacturer and still have problems then switch the manufacturer. Maybe go buy one from a different parts store because they usually do not carry the same product from same manufacturer. Make sure the part is not a refurb. because usually the lowest price products they sell are refurbished items.
But anyways. Make sure while your changing out your locked caliper for a better and new one, make sure the disc is not damaged-no deep lines or groves around the disc.If so I would replace those asap. Their as cheap as 20-30 bucks.
Hope this helped. I just recently changed my locked caliper 2 months ago. No problems sine then and I drive over 100 miles a day.
