Does a 66 have two wheel cylinders on each rear wheel? If so did you bleed all of them. I know I had a 64 with the 2 cylinders and I think my 65 LCF-60 does. They are a real pain.
'65 C-10, 65 L-60, 65 C-80, 72 C-60 & and a bunch of old Chevy cars.
Never time to do it right, always time to do it over.
