I have been having problems with my stock LT1 brakes. OR SO I THINK...my pedal just doesnt feel right (its kinda soft for a sec and then gets rock hard before its even 3/4s down!)
What might be the problem? The car doesnt stop very well either. I bleed the brakes few times now and the problem is still there.

What is the best way to bleed the brakes? I have been doing it according to the haynes manual, start at the back wheel, pump the brake, open the bleeder let if flow for a sec close the bleeder, let go of the pedal etc........Please help!
Thanks

Mine is the exact same way man, I really don't get it either. My work trucks are like super sensitive to the touch and seem to have more stopping power than my Z28?

 

could be air in the ABS system. It has 2 bleeder screws as well (front and back).

What you describe is most likely air in the system, but it could also be piston-knock-back. Some people call it brake piston slap. basically the rotors, for some reason, can tap against the pad and slowly force the pistons back in their bore. This leaves you pushing on the brake pedal to first seat them, and then to apply brake force.

Most likely though? you need to flush the brake lines and bleed the ABS mondle twice. Once before all the bleeding/flush, and once when you're done flushing new fluid into the system. Some go as far as to bleed the ABS a third time once you're taken her for a spin and locked the ABS one or twice (to cycle the cylinders), but I've never seen that as nessesary in the GM Service Manual (unless I missed it).

 

A simple C5 Brake conversion will solve all your problems with brakes.

 

my problem was the stupid ceramic brake pads..went back to good old PFC carbon metalics...car stops on a dime!
