Just Sharing This Brake Master Cylinder Trick

I've had Dot 5 since I did the stop on a dime conversion way back. Steel braided flex hoses new rear cylinders and new calipers so it was time to flush and change the fluid. I have recently upgraded my master to a 2 bolt 15/16 aluminum job from Dr Diff. I like the pedal feel better.

Interesting. Wonder what different feel using the same diameter between the cast and aluminum. You would think it would be the same mechanical advantage.
