BA42.10-N-1003-12TS	Bleed valve to brake caliper	Nm	14	14

Switch on filling unit and set bleed pressure to 2.0 bar.
Remove caps from bleed valves on all brake calipers (1, 2, 3, 4).
Mount vent hose of bleed bottle to bleed valve of rear right brake caliper (1).
Open bleed valve of brake caliper (1).
Bleeding
1. To bleed the hydraulic system of the brake system if the hydraulic system was opened for repair purposes.
  Repeatedly operate brake pedal until new brake fluid flows out without any bubbles.
  
  To bleed the brake system correctly it is absolutely essential to pump the brake pedal throughout the entire bleeding process.
  
  Otherwise brake system malfunctions and a failure of the brake system may occur due to remaining residual air.
  
  To prevent air from being drawn in do not pump the brake pedal in a jerking manner but instead release it slowly.
  
  Otherwise an extension or a repetition of the bleed procedure may be necessary.
  
  Aid of helper required.
  
  The bleed valve of the brake caliper (1) can remain open throughout the entire pumping procedure.
  
  Total quantity of brake fluid required: Approx. 1.7 l.
2. To replace the brake fluid if the brake system's hydraulic system was not opened beforehand for repair purposes.
  Leave bleed valve of brake caliper (1) open until new brake fluid flows out.
  
  Pumping of the brake pedal is not necessary Total quantity of brake fluid required: Approx. 0.8 l.
Close bleed valve of brake caliper (1).
Brake caliper (2, 4)

Brake caliper (1, 3)
Remove vent hose of bleed bottle from bleed valve of brake caliper (1).
Repeat operation steps , to , on remaining brake calipers (2, 3, 4).
Process brake calipers (2, 3, 4) in numerical order.
Fit caps for bleed valves onto all brake calipers (1, 2, 3, 4).
Switch off filling unit.
