Does a slightly higher engine idle effect braking performance?
i installed a 2002 chevy 5.3 in a jeep cj. I also completed a full rear brake installation. The brakes are properly installed and all brakes are fully bled. 1st half of pedal travel doesn't have much stopping power but at end of pedal travel brakes are firm and strong. Is this a description of a master cylinder or possibly a vacuum issue?
Would go with master cylinder booster failure would give hard pedal travel

Thanks for the response!
How could I troubleshoot to verify? Any possibility that this is a proportioning valve issue?

My 2002 5.3 Chevy also seems to idle a bit too high, maybe 300-400 rpm. I haven't installed a tach yet so its just a guess. Would adjusting the throttle plate stop be the correct way to lower the idle rpm?

What you feel is primary piston leakby till you hit seconday then feel resistence. NOT combo valve. As for idle DO NOT adjust throttle computer controled was GM PCM and wiring installed? Idle should be @600-700 in gear

With the CJ, do you feel confident with your bleeding procedure?
