Changing The Brake Fluid

WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

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.

Connect a bleeding device to the brake fluid reservoir.
Switch on the bleeding device. Bleeding pressure is approx. 2.0 bar.
Continue changing the brake fluid at the brake calipers. Do so in the following sequence: rear right/rear left/front right/front left.
Open every bleeder valve until clear, bubble-free brake fluid emerges and until the corresponding change quantity per brake caliper is reached (approx. 250 cm³ ).
Use a transparent hose and a collecting bottle to check the escaping brake fluid accurately for cleanliness, freedom from air bubbles and to determine the brake fluid used.
Tighten the bleeder valves to the specified tightening torque → Tightening Torques .
Switch off bleeding device and remove the adapter on the brake fluid reservoir. The brake fluid level in the brake fluid reservoir must be between the MIN and MAX markings once the vehicle has been filled and bled. Adjust the brake fluid level if necessary.
