Can anyone help me with the likely cause of a grinding like noise emminating
from the front wheels of my 86 Syncro when backing up.  I sounds like
something dragging against the brake rotors but when I take the transmission
out of reverse while still travelling rearward the noise disappears. I
replaced the rotors/pads at 110,000 miles and now have about 170,000.  I may
have some front bearing issues since I notice that I need to pump the brake
pedal a bit to keep the pedal travel in check.  I flipped the front
driveshafts end for end at about 120,000.
