Pressure Bleeding

Fig. 20 ABS/ASR Hydraulic Pressure Reservoir:

1. Turn the ignition off, release the pressure in the pressure reservoir at bleeder valve SP, then close valve, Fig. 20.

2. Connect the filling and bleeding equipment. Use 2 bar power bleeding pressure.

3. Bleed the brake system as previously at the wheels. Let approx. 0.5 liter of brake fluid flow from each wheel brake caliper, so that the lines and the pressure cylinders of the brake calipers will also be filled with fresh brake fluid.

4. Start the engine.

5. Open bleeder valve SP until clear brake fluid flows out with no bubbles.

6. Close bleeder valve SP. Wait for pressure reservoir charging to finish (the charging pump and the return/pressure pump run audibly approx. 30 seconds and shut off).

7. Turn the engine off.

8. Disconnect the filling and bleeding equipment and top up the fluid level in the brake fluid reservoir using DOT 4 type brake fluid.
