My brakes still don't work like they should
I've got a 2008 Chrysler Town and Country Touring Edition with 3.8L V6. I changed the back brakes today, pads, rotors. I had to open the bleeder screws to turn in the caliper pistons with the tool I rented from the parts store. I bled the brakes at all 4 wheels when done, and refilled the brake master cylinder as needed. However, when I start the van I have to pump the brakes in order to stop, rather then just lightly tapping the pedal to get braking. Have I missed a step, or could there be something else wrong with my brake system to cause this weak brake pedal? Also, how do I know whether I need to change the rubber brake hose at the wheel connected to the caliper?
