When was DOT 5 Brake Fluid 1st made or used in cars and trucks?
Hello and welcome
DOT-5 silicone brake fluid - This formulation was achieved in the late 1970s that satisfied DOT criteria. The only manufacturers were using it were Dow-Corning and General Electric.
The DOT 5 were commonly used in the racing scene in the late 70s.
Let me know if this help out.
This may be a legal question.In Massachusetts is it illegal or is it against OSHA policy or law to plug tires instead of patching tires?
