Just coming back to this....what’s disappointing about the brake? In all honestly with normal daily driving stock brakes in mechanical top shape work fine. Performance driving, they may overheat and become less effective. I would argue even the 1LE swap is still going to give you old generation braking power not suitable for modern performance. For high performance use, you need a larger rotor, large caliper with good pads AND a master cylinder to bring it all together. If your stock brakes lack for a stock like application. I would look into issues with the master cylinder, crud or rust in the brake lines causing fluid transfer issues.
