I forgot to ask. Does it pump up or is it half pedal all of the time? Half
pedal standing still or while driving? A loose wheel bearing can cause pad
knockback on the front disc's requiring a lot of pedal before contacting the
rotor. Would happen while driving not always standing still since you'd have
applied the brakes to stop your motion.
