WARNING
Clean, high quality brake fluid is essential to the safe and proper operation
of the brake system. You should always buy the highest quality brake fluid that
is available. If the brake fluid becomes contaminated, drain and flush the system,
then refill the master cylinder with new fluid. Never reuse any brake fluid.
Any brake fluid that is removed from the system should be discarded.
Metal lines and rubber brake hoses should be checked frequently for leaks and external damage. Metal lines are particularly prone to crushing and kinking under the vehicle. Any such deformation can restrict the proper flow of fluid and therefore impair braking at the wheels. Rubber hoses should be checked for cracking or scraping; such damage can create a weak spot in the hose and it could fail under pressure.
Any time the lines are removed or disconnected, extreme cleanliness must be observed. Clean all joints and connections before disassembly (use a stiff bristle brush and clean brake fluid); be sure to plug the lines and ports as soon as they are opened. New lines and hoses should be flushed clean with brake fluid before installation to remove any contamination.
