2012 Mazda 5 Spongy Brake Pedal
This car has had a "Spongy" Brake Pedal for some time now. I've bled the
brakes several times and the issue has not improved. Recently I replaced the
master cylinder and bleed all the calipers still with no help. With the car not
running the pedal feels good but once it's started the sponginess returns.
During by last bleeding process, I noticed that the calipers were slow to react
to pedal pressure. When my helper told me that the pedal was stiff the
calipers still had not grabbed the rotor until about 10-15 seconds after. This
occurred at all 4 locations. Can this be an issue with the ABS module, or do I
have another component that is causing this restriction in the system?
