I replaced pads and rotors all the way around on my 03 CLK500 with 69,000 miles but after bedding them in the brake pedal became "spongy". I already put around 1000 miles on the car but no change in brake feel, it goes about 2" with minimal braking and then grabs. I put cross-drilled rotors and ceramic Posi-quiet pads from R1 performance. When working on brakes I did not bleed any of the calipers, I disconnected ABS plug, and did not add any brake fluid. What possibly may be causing the "spongy/soft feel"? Prior to replacing rotors and pads brake felt like it supposed... is there something that maybe I missed? Any help is really apprieciated...
