Removing brake master cylinder

Information 

• In the event of assembly work at the hydraulic connections, all electric plug connections in the area of the connection point must always be connected. This prevents the inside of the plug connections from being splashed with brake fluid or water  .
• Clean any plug connections that have become dirty or damp during removal and fitting using a lintfree cloth, for example  .
• Brake fluid on electrical contacts (even thinned brake fluid) leads to corrosion and can cause faults in the system  .
• Remove any escaping brake fluid immediately; rinse with water and dry thoroughly if necessary  .
