34 00 027 Replacing fluid in brake system: Notes

WARNING: This page is about a different car, the 2013 BMW Z4, 2012 BMW Z4, 2011 BMW Z4, 2010 BMW Z4, and 2009 BMW Z4. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: When carrying out repairs to the master brake cylinder or hydraulic unit, follow the procedure set out in BLEEDING BRAKE SYSTEM WITH DSC  .
Under certain circumstances it is not possible after the brake system is opened to bleed the brake system fully at the rear EMF brake calipers. If there is still residual air in the rear brake calipers after normal bleeding, it will be necessary to work through an additional bleeding procedure !

Use only BMW-approved brake fluids, see BRAKES - OPERATING FLUIDS

Connect brake fluid changer to expansion tank and switch on.

NOTE: Check relevant equipment manufacturer's operating instructions for each device.
Charging pressure should not exceed 2 bar.
