Removal:
Removal:
Mark brake pads when removing if they are to be reused. They must be fitted in the same place, if not, this will result in uneven braking behaviour!
  Note
Do not separate connectors of parking brake motors.
l  Parking brake not operated.
–  Remove wheels.
The parking brake pistons must be moved back with -VAS 5051-.
Before resetting pistons, draw off brake fluid from brake fluid reservoir. Otherwise, if brake fluid has been replaced it might leak and cause damage.
–  Connecting → Vehicle diagnostic, testing and information system VAS 5051 and selecting functions → Chapter.
–  Do do this, select electromechanical parking brake and „moving parking brake motor pistons forwards and backwards“ function.
–  Move the pistons back using → Vehicle diagnostic, testing and information system VAS 5051.
   
–  Then remove securing bolts from brake caliper; to do this, counterhold on guide pin.
–  Remove brake caliper from brake carrier.
  Note
The resetting of the pistons with → Vehicle diagnostic, testing and information system VAS 5051 is still required but is often not sufficient! The thrust nut in the piston is fitted on a floating bearing, so that the piston can only be compressed but not pulled back. Only the spindle with the thrust nut will be moved back.
  Caution
The piston must be reset beforehand with → Vehicle diagnostic, testing and information system VAS 5051.

–  Now press piston back fully with piston resetting tool -T10145-.
–  Secure brake caliper with wire so that weight of brake caliper does not stress or damage brake hose.
  N47-10025
–  Remove brake pads and pad retainers -arrows-.
Cleanliness:
  WARNING
Never clean the brake system with compressed air; harmful dust particles will be released.
–  Thoroughly clean the brake plate in the areas of contact with the brake pads and remove corrosion.
–  Clean brake caliper.
Only use methylated spirits to clean the brake calliper.
