Bleeding [10/2014 - ]: Procedure

BLEED BRAKE MASTER CYLINDER

NOTE:

To prevent brake fluid from damaging painted surfaces, cover any surrounding parts with a piece of cloth.
Be sure to clean your hands before bleeding the master cylinder to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.

HINT:

If the brake master cylinder sub-assembly is reinstalled or runs out of brake fluid, bleed the brake master cylinder sub-assembly.

Using a union nut wrench, disconnect the 2 brake lines from the brake master cylinder sub-assembly.
