I replaced the front pads on my girl's 2013 3i yesterday, and didn't have any issues. On each side, I jacked it up, removed the tire, removed the caliper, removed the old pads, pushed the piston in with a big C clamp, put the new pads on and reattached the caliper.

After taking it for a test run, it was obvious that the brake pedal was very soft. I had to push it almost to the floor before it would begin to stop. If I pumped the brakes a few times while stopping (to build pressure) it felt normal. I figured I had to bleed the brakes.

I bled the front, one at a time, the way I always have in the past (on other cars .. this is the first brake job on the 3). She sat in the drivers seat, pumped the pedal a few times then held it down, I loosened the bleeder screw, pedal went to the floor, tighten the bleeder screw, and then release pedal. We did this 4x on each side. I added a bit of brake fluid to the reservoir after each side was done. The brake pedal is still soft.

Question: Do I need to bleed the rear brakes as well? I read somewhere that the front & rear brakes share the same fluid "circuit" (not sure what the term is).

 

Have you driven the car to bed in the new pads? You wont get a good pedal until the pads have bedded in.
