I thought my 98 Subaru had a hill-stopper feature, but found nothing in the owners manual. Then I discovered left front wheel and brake surfaces are very hot after driving while other 3 are only mildly warm. No dust shields. Brake pedal travel seems OK, with no apparent binding. Pad looks good, with sufficient material left. Rotor is evenly polished, with no gouges. No evidence of leakage at wheel or master. Is there something to check first, or do I go right to the master cylinder? Is there an adjustment, either at the master or the caliper? Can I lubricate the caliper slides while they're still installed? With what. Penetrating oil? Thanks for the help

If only one side is dragging, jack that tire up and block the rear wheels, put car in neutral, if whell is actually locked or dragging, open the bleeder screw, does it spin freely? If yes replace the flex hose, if no, replace the caliper...If it was mine I would do both sides, they are the same age and generally in the same condition! If you do not have ABS brakes, the hill holder or PHV, holds pressure on the left front, and right rear, May work the same on ABS models too, not sure. Clutch could be out of ajustment, and ball inside the PHV may be stuck in a partially on position. The only way to tell is before you run the hose test, open the line at PHV that goes to the left front. if wheel spins, the PHV is NG, or clutch needs adjustment.
