Information
- Check brake fluid quality. Use only new DOT 4 brake fluid.
- Brake fluid can be ordered using the Porsche Electronic Parts Information (PET).
- There are two bleeder valves on the brake calliper. Brake fluid must be drained at both bleeder valves.
Change the brake fluid at all four brake callipers one after the other. Do this in the following sequence: rear right/rear left/front right/front left.
1. 4.1 Use a transparent hose and a collecting bottle to check the escaping brake fluid for cleanliness, absence of air bubbles and to determine the amount of brake fluid used.
2. 4.2 Drain brake fluid at both bleeder valves on each brake calliper.
  Per brake calliper: > Change brake fluid (on each wheel) approx. 250 cm3
Tighten bleeder valves to the stipulated tightening torque and remove bleeder hoses.
Front bleeder valves (grey cast iron): > Tightening torque 14 Nm (10.3 ftlb.)

Front bleeder valves (PCCB): > Tightening torque 20 Nm (14.8 ftlb.)

Rear bleeder valves (grey cast iron): > Tightening torque 14 (1 0.5 ftlb.) Nm

Rear bleeder valves (PCCB): > Tightening torque 14 Nm (10.5 ftlb.)
Switch off the bleeding device and remove the adapter at the reservoir.
Carry out a visual inspection of the brake fluid level and correct the brake fluid level if necessary. The brake fluid level must be between the MIN and MAX markings. -arrow-
