so yesterday i heard brake noise from the left rear...i figured time to change pads. well when i got in there, the outside pad on that side was almost new, while the inside was grinding into my rotor. i am replacing all 4 rotors this spring and it is not warped so i did not have it turned. i got the pistons screwed back in, and finished the brake job with the exception of bleeding the brakes, i did not have another person there nor did i have time. well now my brakes are really spongy. and take FOREVER to stop. when i got to work...about a 20 minute drive, that wheel was unreasonalbly hot and smelled of brakes....bad. any ideas, aside from a ful brake bleed.
