okay -- follow me, current problem each front brake caliper 'grabs' through the day, not both at the same time , left / right take turns, it is 'fine' when cold starts grabbing through the day, the pedal is normal then feels too high when pads are 'dragging' - i have replaced one caliper, both hoses, master cylinder, now all this started couple months ago - right rear brake line rusted through , wife drove it a few miles leaking, prob got air in ABS system, thought it was master cylinder, took it to shop they said had to "power flush" it, So Now What ??
