A braking setup is a complicated system. Piles of R&D has gone into engineering. It isnt a system that you can add a part or a few parts and notice a dramatic improvement. I don't know how or what really happened when I panic stopped my truck but it is not happening again. I don't even need to know. Anew older thread on this message board put the pieces together for me. It is dangerous to ride around with a mismatched combination of parts. Your calipers, rotors and pads need to match your master cylinder and booster and pedal, and your drums and shoes, and your proportioning valve. Then of course all parts must be in good repair adjustment and working order. This all factored together allows you to controllably apply proper brake bias to stop your truck safely. Too much or not enough effect from any of these parts compromises performance and in this case safety.
JB6 is the RPO on my glove box sticker. It designates the GVWR of my truck at 7200# and that I have a vacuum brake booster.
