Changing Brake Fluid

Information 

• Observe brake fluid quality. Use only new DOT 4 brake fluid. 
• The brake fluid change interval is two years using Super DOT 4 brake fluid. 
• This brake fluid is available under the following part numbers: Quantity supplied: 1 litre = 000.043.203.66; 30 litres = 000.043.203.67. 
• Drain brake fluid from every brake calliper at both bleeder valves. 
• There are two bleeder valves on the brake calliper. Brake fluid must be drained at both bleeder valves. Observe specified sequence: Bleed the outer bleeder valve first.

2. Connect a bleeding device to the reservoir -2-  .
3. Switch on the bleeding device. Bleeding pressure is approx. 2.0 bar.
4. Continue changing the brake fluid at the brake callipers. Observe the sequence specified on the Porsche System Tester: Front left/Front right/Rear right/Rear left.
5. Open every bleeder valve until clear, bubble-free brake fluid emerges and until the corresponding change quantity per brake calliper is reached (approx. 250 cm³ ).
6. 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.
7. Tighten the bleeder valves to the specified tightening torque

   and remove the bleeder hoses.

8. Switch off the bleeding device and remove the adapter at the reservoir. The brake fluid level in the reservoir must be between the MIN and MAX markings after filling and bleeding the vehicle -1-  . Correct the brake fluid level if necessary.
