First time having manual brakes, are mine bad?

A M/C is merely a pump, nothing magic.
A piston displacing fluid.
A servo/wheel cylinder receives the fluid, and changes it to mechanical motion.
The mounting is/can be vehicle specific.
I build race cars, I generally use Toyota M/C's because they are a vast variety if bore sizes, and it really helps having a remote reservoir .
Make of parts is irrelevant, mounting and bores are all that's important .
Racecar tires are wide and sticky, and heavily used, they also need to work .
The only magic is remembering this dude .
