Hard to see my facial expression, but I am agreeing with you. Throttle
not leaking with original type fluid, not a safety issue, so continue on
Brakes are safety, so if DOT 5 caused leaks past a worn seal in a
braking system, it is time to fix the seal, as eventually the seal would
pass other fluid compositions. Better a brake failure in a shop than on
Just like "Mechanic in a can" type stop leaks. I would use them in most
any vehicle system except brakes.
My Hysteria was directed at people who discover DOT 5 leaking from a
brake system, and blame the fluid. It means the brake system needs
repair, they just found it earlier rather than later.
