What a difference!
I usually use stock fluid to do maintenance. I saw the youtube video, https://www.youtube.com/watch?v=qkIowmqOFRg, where they show what a difference brake pads and fluid make. I tried the fluid and the brake pedal feels much better. I have a GMC Canyon that had soft brake pedal. The truck is not a race car or stop like one. But it feels much better than original. I did not measure the before and after. I wish I had because I am interested in knowing how much the difference is.
