Thanks Guys for helping me get the confidence back on the brake issue.
My VERY FIRST CAR was a (different) '65 K GT Convertible that I bought for just $500.00 at age 16 back in 1973, I didn't know anything about brakes back then, all I wanted to do was to go FAST!!
NEVER did any brake work on that car, never added any fluid, had a mechanic replace the pads once as I recall.
I don't remember ANY particular vehicle back in the days of single master cylinders having wrecks as a result of a master cylinder failing suddenly.
Thanks Again!!
