I put new calipers at all 4 corners of the burb. I've just driven it on two short runs (1/4 mile or less).......I made it stop alot. The front rotors are getting dang hot, the rears are maybe getting barely warm.. It feels like I can kinda lock up only the front, the pedal is a bit spongey. It also kinda maybe feels like the front calipers are sticking closed after I let off?? Who's got their money on it being a bad master cylinder? Who thinks I just need to bleed the piss out of the brakes AGAIN..? I'm stumped... EDIT: my brake light is also on.
