Several months ago I changed the brakes and rotors in my 1999 GMC Suburban. I took the calipers off, and used a set of channel locks to slowly compress the piston back in before fitting the new brake pads. Ever since I replaced them, it's felt a little more *spongy* than it used to. It stops just fine, but seems like I have to push "further" than normal, just a little bit. It's such a small difference that I've been driving it and feel safe driving it, I've hauled my trailer through the mountains just fine. Tonight I was helping my Dad change his front brakes in a 1998 Chevy truck and used the same method, and he said he thought they felt a little more spongy than they used to be. My question - is this the proper method for changing the front brakes pads (compressing the piston without bleeding the brakes)? Again, it's stopping just fine and I feel safe, it just feels a little different than before. Thanks for any suggestions.
