Flushing Brake Hydraulic System
FLUSHING BRAKE HYDRAULIC SYSTEM
The entire hydraulic system should be thoroughly flushed with clean brake fluid if there is any doubt as to the grade of fluid in the system, or if fluid has
been used that contains the slightest trace of mineral oil.
All rubber parts which have been subjected to the contaminated fluid must be replaced before flushing the system.
