i have a chevy pickup with the duramax diesel in it. might just be my truck, but the pedal feels strange. on regular power brakes, or manual for that matter, you know how the pedal feels when pressure starts to build in the brake system? well, on my truck that feeling is pretty much not there. pedal is soft feeling, and yes i have bled the snot out of them. drove a friends truck and his feels the same. truck stops ok, considering it weighs over 3 tons. but the pedal feeling is just not right......kind of feels like there is no or very little brakes would be a good way to put it......
