2008 Mustang GT. So, installed new OEM style calipers/hawk pads/rotors on the back. New 14" rotors, hawk pads, and 4 piston (Brembo style) calipers on front. When I started by removing the old right/rear caliper, a bunch of fluid dripped out before it dawned on me to keep the master cylinder topped off. I topped it off, and it took about 1/3 quart, but I didn't think to look to see if MC had run dry. Besides, I didn't pump the brakes or do anything to suck air in. So, I went along with the install, topping off the MC occasionally going forward. Anyway, got everything installed, bled, and pads properly bedded per Hawk instructions. The brakes stop the car fine, but the pedal goes further down than I *THINK* it is supposed to before engaging. Once engaged, the car stops fine and the pedal never goes to the floor. But, it feels like it goes an inch or two before any engagement. In contrast, my 2017 Fiesta ST will jerk you forward when you press the pedal 1/2". I used a Motive bleeder and bled until nothing but nice clear, new fluid was coming out. I went in the right order for the 4 corners (RR, LR, RF, LF). But, I apparently did the wrong order on the 4-piston calipers, cause I bled the outside bleeder first. I don't think that would have mattered. All the pads appear to be lightly resting on the rotors as they should, and the handbrake works fine. Now, I'm starting to wonder if I'm going to have to pay someone to bleed out the ABS . . . and perhaps the master cylinder?
