The most probable cause is stuck slider pins on the caliper holder. These can be fixed with heat if they wont come out. Put a bit of grease (thick grease) on each one before re-assembly. Also make sure that your pad retaining brackets are well greased and free of rust and road debris (dirt, dust etc.) so the pads can easily slide towards the rotor and then back away when the pedal is depressed and released. Old rubber brake hoses can crack internally. A flap of the hose material may allow fluid to apply the brakes but prevent the reverse flow of the fluid causing brake drag. If your brake lines are old you may wish to replace them. you need to rebuild the brake calipers Or buy a rebuilt one for $40 at NAPA or any other parts store. You can swap this yourself very easily, especially if you own a Haynes Repair Manual for Subaru Legacy. YFC

i don't know if it helps, but my '99 legacy outback was making a knocking sound. turned out that the oring on the brake caliper pin had worn out, and the pin was kind of knocking around.
its on the top drivers side under the clutch master cylinder or the brake master cylinder easy to remove three bolts i believe
