Bendix DOT4 Brake Fluid Colour Change!
Nov 26, 2019
The U.S. Department of Transport have colour requirements in the U.S. FMVSS 116; Motor vehicle brake fluids standard for DOT4 Brake Fluid. To ensure the Bendix product meets the requirements we have changed the Bendix DOT4 fluid colour from blue to straw, as per below.
Section 571.116 Standard No. 116; Motor vehicle brake fluids.
- S5. Requirements. This section specifies performance requirements for DOT 3, DOT 4 and DOT 5 brake fluids; requirements for brake fluid certification; and requirements for container sealing, labelling and colour coding for brake fluids and hydraulic system mineral oils.
- S5.1.14 Fluid colour. Brake fluid and hydraulic system mineral oil shall be of the colour indicated:
- DOT 3, DOT 4, and DOT 5.1 non-SBBF – colourless to amber.
- DOT 5 SBBF – purple. Hydraulic system mineral oil – green.
Why have colour requirements?
The simplest reason is to ensure you’re using the right fluid. All ether-based fluids are clear to amber while all silicone-based fluids are purple. While the different colours give a quick indication as to the composition, the clarity can tell how contaminated the fluid is. Ideally, brake fluid should be clear and clean. Dark and murky fluid indicates that the fluid has collected dirt, debris, and even moisture from the system and it’s now time to replace it.
