Most likely it's your pad choice.I upgraded my pads and rotors on my 19 PP1 and they don’t have the same bite or stopping force as the stocks did. I did the bedding procedure twice an still feels off. Does bleeding the brakes seem like a likely culprit or something else?
What is the exact brand/model?semi metallic pads
Running two piece rotors with semi metallic pads. Definitely not grabbing like the stock and pedal feel insanity lazy.
Brake & Front End Magazine is a repair industry periodical. Boldface theirs.Brake & Front End Magazine said:Semi-metallic friction materials typically require a little more pedal effort when they are cold and work best when the brakes are warm or hot.
You still haven't told us what pads you got. Till you do that, this is all speculation and we can't help.Steeda 2 piece rotors and even after use the initial bite is not as strong and the brake force is not as strong either. Just a simple rotor and pad change which I’m no novice at and it should not perform worse than the stock set up. I even did the bedding procedure twice and still no big improvement. I thought maybe the pads glazed.
There you go, no name pads. Garbage.
