Front brake pads FN3: Removing and installing
Removal:

  A46-0040
–  Unscrew both guide pins from the brake calliper and remove them.
–  Remove the brake calliper housing and place it so that the weight of the brake calliper does not rest on or damage the flexible tube of the brake.
  WARNING
Do not leave brake calliper hanging from brake hose but secure it to bodywork using a suitable cable tie or wire. Take care that brake hose is not damaged by weight of brake components.
Do not apply brake when brake calliper is removed.
–  Take brake pads out of brake calliper housing or from brake carrier.
  Note
Push brake piston into cylinder with resetting tool before inserting brake pads. Before pressing the piston back, draw off brake fluid from the reservoir with a bleeder bottle. Otherwise, fluid can overflow and cause damage, particularly if reservoir has been topped up.
  A46-0041
–  Press piston back.
Installation
  A46-10042
–  Install brake pad with retaining spring in brake calliper housing (on piston).
  Note
The inner pad (with spring) has an arrow. The arrow must point in direction of brake disc rotation when moving forwards. Noises can be caused from incorrect assembly.
  A46-0043
–  Remove protective foil from back plate on outer brake pad.
–  Fit outer brake pad onto brake carrier.
–  Screw the brake caliper to the brake support plate with the two guide pins, tightening them to 25 Nm.
–  Fit the two protective covers.
–  Insert retaining spring into brake calliper housing.
–  Connect brake pad wear indicator connector.
–  Mount the wheels → Running gear, shafts, steering; Rep. gr.44
  Note
t  Insert the retainer spring under the brake carrier once it has been inserted into the two holes. If this is incorrectly fitted then the wear on the outer pad cannot be corrected, this will gradually extend the pedal stroke.
t  After fitting the brake pads, operate the brake pedal strongly with the vehicle stopped so that the brake pads adopt the position corresponding to normal operation.
–  Check the brake fluid level and refill in case of doubt.
