Perform this procedure if the gearbox is removed. If the gearbox is not removed, refer to Hydraulic System Bleeding to bleed slave cylinder.
- Connect a 450 mm long piece of clean, transparent 8 mm plastic hose to the slave cylinder delivery pipe connection.
- Fully depress the release bearing once and then release it. The slave cylinder seal remains in its inner position.
- Fill the plastic hose with brake fluid to a level of about 350 mm.
- Connect Pressure/vacuum pump (30 14 883) to the plastic hose. Use a 6 mm plastic hose (this is used to provide a tight seal).
- Pump up pressure until the slave cylinder seal moves out and brake fluid runs down into the slave cylinder. The pressure increases when the seal has reached its farthest point.
- Remove the pressure/vacuum pump and carefully press in the release bearing to its stop. Note the air bubbles in the plastic hose.
- Repeat points 5 to 6 a few times until no air bubbles are visible in the hose.
- Leave the slave cylinder seal in its innermost position. Drain and remove the plastic hose.
