did you change the brakes, or did you have a shop do it...? if a shop, take it back and have them fix it right......check the fluid and top it off, and bleed the brakes....if the pads were installed correctly, this should correct the problem..

Sounds like you might have some air in your brake lines.

After bleeding the brakes, your pedal will still be somewhat spongy. Some members reported that after getting on your brakes and letting the ABS kick in helps bring that high pedal feel. This was true for my car as well. Might want to give it a try.

Mine as well. I had the spongy brake pedal until one morning on my way to work I had to really hit the brakes. The ABS kicked in and have had about 1/2 inch of travel since.

i should have prased this post differantly i have a good pedel most of the time the truck stops well at speed but if you just go slow and try and stop it ocassionally is spongy and goes to floor for instance back out driveway and try and stop its got a soft pedel or if you do a nice slow roll in forward same thing but never all the time . under normal driving stops fine i put the brakes on the have been bleed nothing is sticking calipers function good slide pins are free and well loobed . its either abs issue or master cylinder just not sure

Spongy brake pedal

Assuming no air in line and brake hoses are all good, Chevy brakes tend to be a little on the spongy side. I have 2002 and 224 TBs, and both have a spongy pedal compared to my Ford Expedition.
