Changing Brake Fluid

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Observe brake-fluid quality. Use only new DOT4 brake fluid.
The brake-fluid change interval using Super DOT4 brake fluid is two years.
This brake fluid is available under the following part numbers: Quantity supplied 1 liters = 000.043.203.66 container volume. 30 liters - 000.043.203.67.

Fill reservoir to its top edge with new brake fluid.
Connect a bleeding device to the brake fluid reservoir.

Switch on the bleeding device. Bleeding pressure approximately 2.0 bar.
NOTE:
- Drain brake fluid on every brake caliper on both bleeder valves.
Continue brake fluid change at the brake calipers (no special sequence).
Open every bleeder valve until clear, bubble-free brake fluid emerges and until the corresponding change quantity per brake caliper is reached (approximately 250 cm3).
Use a transparent hose and a collecting bottle to check the escaping brake fluid accurately for cleanliness, lack of air bubbles and to determine the brake fluid used.
Some brake fluid is also drained off at the bleeder valve of the clutch slave cylinder (approx. 50 cm3).
Switch off and disconnect the bleeding device. Correct the brake fluid level if necessary.
