BRAKE FLUID CHECKS
IMPERATIVE: Respect the safety and cleanliness requirements.
WARNING: Brake fluid is toxic to health. Avoid any contact with your skin or with your eyes. If there is contact with your eyes, rinse immedia-
tely with copious amounts of water for several minutes.
WARNING: Brake fluid is highly corrosive to paintwork. If there is spillage onto the bodywork, clean the surface immediately.
Tools: Brake fluid tester (*):
Supplier Reference Type
SURETEST TLF
DOW AUTOMOTIVE BETATEST Measures the boiling point of brake fluid
FACOM OUTILLAGE DF.16
EBT 06.1 Measures the rate of hydrometry of brake fluid
(*) The list not exhaustive, refer to the catalogue "Tools and Equipment".
Checks.
Remove the filter of the brake fluid reservoir.
IMPERATIVE: Any pollution of the brake fluid is forbidden. The brake fluid should be limpid and free of suspended matter or sediments.
Check the brake fluid, following the method recommended by the supplier of the testing equipment.
Test values:
Brake fluid Minimum boiling point «Humid»
DOT 3 140°C
DOT 4 155°C
SUPER DOT 4
180°C
DOT 5
NOTE:If the tested value is lower than the minimum "humid"boiling point or within a tolerance of +10 %of this value, replace the brake fluid
(see corresponding operation).
IMPERATIVE: Use exclusively the hydraulic fluids that are approved and recommended.
