First time having manual brakes, are mine bad?

i just replaced the brakes on my 67 dart gt vert 340 kh 4 piston calipers
the 2225541 master only had front brakes only could find it on ebag for silly money
I read all the post here went with the 15/16 bore from auto zone 57 bucks lifetime warranty
new copper lines all around the pedal feel is great very pleased the bore size is not the issue
