The Brakes on my DD just aren't what they should be. The car has new pads and rotors front and back and rubber lines up front. I just replaced the lines a month ago and had a heck of a time getting them bled. I could get the master cylinder to bench bleed fine but once I hooked the lines back up the pedal would go soft. I ended up using a pump to push fluid through the lines to get most of the air out and then was able to get them to bleed. Under normal braking they feel ok, the pedal is a bit stiff compared to my TD's, and when you step on them hard they seem to go down almost to the floor and I can't lock up the tires or get the ABS to kick in. I'm leaning toward the MC being bad but thought I'd ask before I go replacing it.
