Re: [Chrysler300] 300g brake system

[Marshall R Larson <yelof@xxxx>]

Sounds like the brake shoes are not adjusted almost to the drums when the
brakes are at rest. The brake return springs will always try to collapse
the wheel cylinders if the adjusters don't limit the travel of the shoes
hold them near the drum. 
The number of pumps it takes to move enough fluid to push the shoes to
the drums depends only on how far they have to move. When the shoes
reach the drums, the pedal becomes firm and stays firm. When the pedal
is released the springs return the shoes to their rest position and the
cycle is repeated the next time braking is required. If there were also
air in the system, the cycle explained above would be the same but the
pedal would always feel spongy. 
If it were only air in the system, one pump of the pedal would probably
be enough but the pedal would always feel spongy
