Quick question for ya Zeph:

My car's been having problems with the brakes.
They were sticking, like whenever I go to stop and press the pedal down they act like I'm pressing it down all the way. Then when I let go of the pedal the brakes are still engaging and slowing me down like I never took my foot off the pedal at all. They stayed engaged even as I accelerated, and wouldn't release until I hit 20mph.
Just recently I replaced the pads and rotors with all new parts and the problem seems to be resolved for the most part. My only problem now is that it seems that the brakes are still sticking some when I accelerate. The way I can tell is that when I start off from a red light or stop sign, the car does a kind of chugging...almost like a train or something.
I'm hoping the chug is just from the new parts settling in, or in need of slight adjustment. However, do you think it could be something else besides the pads and rotors? Could it be the master cylinder causing the problem?

Jam it back in, in the dark.
