Front or rear, if its the rear, the axle seal has probably failed and the rear end grease is leaking out into the brake area so the brake friction material has been contaminated with grease and will need replacement as well as the grease seal. Front or Rear and are you sure its not brake fluid leaking, Lets us know and we can give an estimate.
